The [[International Hydrographic Organization]] defines the Persian Gulf's southern limit as "The Northwestern limit of Gulf of Oman". This limit is defined as "A line joining Ràs Limah (25°57'N) on the coast of [[Arabian Peninsula|Arabia]] and Ràs al Kuh (25°48'N) on the coast of Iran (Persia)".<ref name="IHO">{{cite web|year=1953|title=Limits of Oceans and Seas, 3rd edition|url=https://iho.int/uploads/user/pubs/standards/s-23/S-23_Ed3_1953_EN.pdf|archive-url=https://web.archive.org/web/20111008191433/http://www.iho-ohi.net/iho_pubs/standard/S-23/S23_1953.pdf|archive-date=8 October 2011|access-date=28 December 2020|publisher=International Hydrographic Organization}}</ref>
This inland sea of some 233,000&nbsp;km² is connected to the [[Gulf of Oman]] in the east by the [[Strait of Hormuz]]; and its western end is marked by the major [[river delta]] of [[Arvandrud]], which carries the waters of the [[Euphrates]] and the [[Tigris]]. Its length is 989 kilometres, separating mainly [[Iran]] from [[Saudi Arabia]] with the shortest divide of about 56 kilometres in the Strait of Hormuz. The waters are overall very shallow and have a maximum depth of 90 metres and an average depth of 50 metres.

In [[Iran]], this is called "Arvand Rud" ({{lit|Swift River}}). Its length is {{convert|989|km|0|abbr=off}}, with Iran covering most of the northern coast and [[Saudi Arabia]] most of the southern coast. The Persian Gulf is about {{convert|56|km|0|abbr=on}} wide at its narrowest, in the Strait of Hormuz.

[[List of islands in the Persian Gulf|Various small islands]] also lie within the Persian Gulf, some of which are the subject of [[Territorial disputes in the Persian Gulf|territorial disputes]] between the states in the region.
==Oil and gas==
The Persian Gulf and its coastal areas are the world's largest single source of crude oil and related industries dominate the region. [[Al-Safaniya]], the world's largest offshore [[oilfield]], is located in the Persian gulf. Large gas finds have also been made with Qatar and Iran sharing a giant field across the territorial median line (North Field in the Qatari sector; South Pars Field in the Iranian sector). Using this gas, Qatar has built up a substantial [[liquified natural gas]] (LNG) and petrochemical industry.
 
===Exclusive economic zone===
The oil-rich countries (excluding Iraq) that have a coastline on the Persian Gulf are referred to as the ''[[Persian Gulf States]]''. Iraq's egress to the gulf is narrow and easily blockaded consisting of the marshy river delta of [[Arvandrud/Shatt al-Arab]], which carries the waters of the [[Euphrates River|Euphrates]] and the [[Tigris River]]s, where the left (East) bank is held by Iran.

==Etymology==
|-
The experts, who have worked on the name of Persian Gulf, became unanimous considering the name of Persian Gulf as the correct term. For at least during the past 2500 years, i.e. from the rise of the [[Achaemenids|Achaemenid dynasty]] (550-330 B.C.) there has never been seen such a consensus in the [[Middle East]] among writers and historians on one name during the past twenty-five centuries. The rise of the Achaemenid dynasty, and center of power which was from the province of Pars (Persis, or modern Fars) in the southwestern region of the Iranian plateau. Consequently in the Greek sources, the body of water that bordered this province came to be known as the Persian Gulf.<ref>Touraj Daryaee, ''The Persian Gulf Trade in Late Antiquity'', Journal of World History, Vol. 14, No. 1., March 2003, ([http://www.historycooperative.org/journals/jwh/14.1/daryaee.html ''LINK'']); accessed Fenruary 09, 2007</ref>

During the years: 550 to 330 B.C. coinciding with sovereignty of the first [[Persian Empire]] on the Middle East area, especially the whole part of Persian Gulf and some parts of the [[Arabian Peninsula]], the name of "Pars Sea" has been widely written in the compiled texts.<ref>Working Paper No. 61, ''UNITED NATIONS GROUP OF EXPERTS ON GEOGRAPHICAL NAMES'', dated March 28, April 4, 2006 ([http://unstats.un.org/unsd/geoinfo/gegn23wp61.pdf]); accessed February 09, 2007</ref>
 
=== Islands ===
In the travel account of Pythagoras, several chapters are related to description of his travels accompanied by [[Darius the Great]], to [[Susa]] and [[Persepolis]], and the area is described. From among the writings of others in the same period, there is the inscription and engraving of Darius the great, installed at junction of waters of Arabian Gulf (Ahmar Sea = Red sea) and Nile river and Rome river (current [[Mediterranean]]) which belongs to the 5th century BC where, Darius, the king of Achaemenid Empire has named the Persian Gulf Water Channel: '''Pars Sea'''.<ref>Working Paper No. 61, ''UNITED NATIONS GROUP OF EXPERTS ON GEOGRAPHICAL NAMES'', dated March 28, April 4, 2006 ([http://unstats.un.org/unsd/geoinfo/gegn23wp61.pdf]); accessed February 09, 2007</ref>

The Persian Gulf is home to many islands such as Bahrain, an Arab state. Geographically, the biggest island in the Persian Gulf is [[Qeshm island]], belonging to Iran and located in the [[Strait of Hormuz]]. Other significant islands in the Persian Gulf include [[Greater Tunb]], [[Lesser Tunb]] and [[Kish Island|Kish]] administered by Iran, [[Bubiyan Island|Bubiyan]] administered by Kuwait, [[Tarout]] administered by Saudi Arabia, and [[Dalma (island)|Dalma]] administered by UAE. In recent years, there has also been the addition of [[artificial island]]s for [[tourist attraction]]s, such as [[The World Islands]] in [[Dubai]] and [[The Pearl Island]] in [[Doha]]. Persian Gulf islands are often also historically significant, having been used in the past by colonial powers such as the [[Portuguese Empire|Portuguese]] and the [[British Empire|British]] in their trade or as acquisitions for their empires.<ref>{{Cite web|last=Ramerini|first=Marco|title=Portuguese in the Arabia and the Persian Gulf|url=http://www.colonialvoyage.com/eng/asia/persian_gulf/index.html|archive-url=https://web.archive.org/web/20150911015234/http://www.colonialvoyage.com/portuguese-persian-gulf-arabian-peninsula/|archive-date=2015-09-11|access-date=2010-11-27}}</ref>

{{Mainarticle|Persian Gulf naming dispute}}
Since the 1960s with the rise of Arab nationalism ([[Pan-Arabism]]), starting with [[Gamal Abdel Nasser]]'s [[Arab Republic of Egypt]], some Arab countries, including the ones bordering the Persian Gulf, have adopted the term "Arabian Gulf" (in [[Arabic language|Arabic]]: الخلیج العربي ''al-khalīj al-ʿarabī'') to refer to the waterway.<ref>Niusha Boghrati, ''Omission of 'Persian Gulf' Name Angers Iran'', World Press.com, dated December 28, 2006 ([http://www.worldpress.org/Mideast/2616.cfm ''LINK''])</ref> This is controversial and not commonly used outside of the Arab world, nor is it recognized by the [[United Nations]]<ref>UN Map ([http://www.un.org/depts/dhl/maplib/docs/escwa.pdf ''LINK''])</ref><ref>UN Map of Iran([http://www.un.org/Depts/Cartographic/map/profile/iran.pdf])</ref><ref>UN Map Map of Western Asia, ([http://www.un.org/Depts/Cartographic/map/profile/westasia.pdf])</ref> and other international organizations. The United Nations on many occasions has requested that only "Persian Gulf" be used as the official and standard geographical designation for the body of water.<ref>([http://www.worldpress.org/Mideast/2616.cfm])</ref> "Arabian Gulf" is also an ancient name for the [[Red Sea]].<ref>Working Paper No. 61, ''UNITED NATIONS GROUP OF EXPERTS ON GEOGRAPHICAL NAMES'', dated March 28, April 4, 2006, p.2 ([http://unstats.un.org/unsd/geoinfo/gegn23wp61.pdf])</ref> [[Hecataeus]] (472 to 509 B.C.) can be stated where Persian Gulf and [[Red Sea|Arabian Gulf]] (Red Sea) have been clearly shown.

== Oceanography ==
In the world map of Diseark (285-347 B.C.) too, Persian Gulf and Arabian Gulf have been clearly distinct. At the same time, many maps and deeds prepared up to the 8th century by the historians such as [[Arrian]]<ref>Arriann, "Alexander Fleet in the Persian Gulf", in ''Anabasis Alexandri'': Book VIII (INDICA)</ref> [[Hecataeus]], [[Herodotus]], Hiparek, Claudius Batlamious, Krats Malous,…… and in the Islamic period, [[Muhammad ibn Mūsā al-Khwārizmī|Khwārizmī]], Abou Yousef Eshagh Kandi, [[Ibn Khordadbeh]], [[Al-Battani|Batani (Harrani)]], [[Ali al-Masudi|Mas'udi]], [[Ahmed ibn Sahl al-Balkhi|Balkhi]], [[Istakhri|Estakhri]], Ibn Houghal, [[al-Biruni|Aboureyhan Birouni]] and others, mention that there is a wide sea at south of Iran named “Pars Sea”, “Pars Gulf”, “Fars Sea”, “Fars Gulf”, “Bahre Fars”, “Sinus Persicus” and “Mare Persicum” and so on. In a book, named “Persilus Aryateria”, the Greek traveller of the 1st century A.D. has called the Red Sea as Arabian gulf; the Indian ocean has been named Aryateria Sea; the waters at Oman Coast is called Pars Sea; Barbarus region (between Oman and Yemen coast are called belonging to Pars, and the Gulf located at south side of Iran is named: Persian Gulf. By describing the water body, the life of Persians living at both sides have also been confirmed.<ref>Working Paper No. 61, ''UNITED NATIONS GROUP OF EXPERTS ON GEOGRAPHICAL NAMES'', dated March 28, April 4, 2006 ([http://unstats.un.org/unsd/geoinfo/gegn23wp61.pdf]); accessed February 09, 2007</ref>
The Persian Gulf is connected to the Indian Ocean through the Strait of Hormuz. Writing the water balance budget for the Persian Gulf, the inputs are river discharges from Iran and Iraq (estimated to be {{convert|2000|m3}} per second), as well as precipitation over the sea which is around {{convert|180|mm|in|abbr=on}}/year in [[Qeshm Island]]. The evaporation of the sea is high, so that after considering river discharge and rain contributions, there is still a deficit of {{convert|416|km3}} per year.<ref>{{Cite journal|last1=Pous|first1=Stéphane|last2=Lazure|first2=Pascal|last3=Carton|first3=Xavier|title=A model of the general circulation in the Persian Gulf and in the Strait of Hormuz: Intraseasonal to interannual variability|journal=Continental Shelf Research|volume=94|pages=55–70|doi=10.1016/j.csr.2014.12.008|year=2015|url=https://archimer.ifremer.fr/doc/00244/35563/|bibcode=2015CSR....94...55P}}</ref> This difference is supplied by currents at the [[Strait of Hormuz]]. The water from the Persian Gulf has a higher salinity, and therefore exits from the bottom of the Strait, while ocean water with less salinity flows in through the top. Another study revealed the following numbers for water exchanges for the Persian Gulf: evaporation = –{{convert|1.84|m|ft|abbr=on}}/year, precipitation = {{convert|0.08|m|ft|abbr=on}}/year, inflow from the Strait = {{convert|33.66|m|ft|abbr=on}}/year, outflow from the Strait = -{{convert|32.11|m|ft|abbr=on}}/year, and the balance is 0&nbsp;m (0&nbsp;ft)/year.<ref>{{Cite journal|last1=Xue|first1=Pengfei|last2=Eltahir|first2=Elfatih A.

Most recently, at the Twenty-third session of United Nation in March-April 2006, the name 'Persian Gulf' was confirmed again as the legitimate and the official term to be used by members of United Nation.<ref>Working Paper No. 61, ''UNITED NATIONS GROUP OF EXPERTS ON GEOGRAPHICAL NAMES'', dated March 28, April 4, 2006, p.2 ([http://unstats.un.org/unsd/geoinfo/gegn23wp61.pdf])</ref>

During the years 550 to 330 BC, coinciding with the sovereignty of the Achaemenid Persian Empire over the Middle East area, especially the whole part of the Persian Gulf and some parts of the [[Arabian Peninsula]], the name of "Persian (''Pars'') Sea" is widely found in the compiled written texts.<ref name="unstats.un.org"/>
== British residency==
{{Mainarticle| British Residency of the Persian Gulf}}
From 1763 until 1971, the [[United Kingdom]] maintained varying degrees of political control over some Persian Gulf states, including the United Arab Emirates (originally called the "Trucial Coast States") and at various times Bahrain, Kuwait, Oman, and Qatar.
 
At the same period, there is the inscription and engraving of Darius the Great, which belongs to the fifth century BC:<ref name="unstats.un.org"/> King Darius says:<ref>{{Cite web|url=https://www.livius.org/sources/content/achaemenid-royal-inscriptions/dz/|title=DZ – Livius|website=www.livius.org|access-date=2019-03-28}}</ref>

==History==
===Ancient history===
The region of the Persian Gulf has been inhabited since the [[Paleolithic]].<ref name="Rose2010" /> During most of the [[Last Glacial Period]] (115,000–11,700 years [[Before Present]]), due to lowered sea levels (reaching around {{convert|125|metres|ft}} metres below present values during the [[Last Glacial Maximum]]) combined with the shallow depth of the Gulf (on average around {{convert|35|metres|ft}} and at max around {{convert|100|metres|ft}} metres depth) most of the Persian Gulf was exposed as dry land,<ref>{{Cite journal |last=Lambeck |first=Kurt |date=July 1996 |title=Shoreline reconstructions for the Persian Gulf since the last glacial maximum |url=https://linkinghub.elsevier.com/retrieve/pii/0012821X96000696 |journal=Earth and Planetary Science Letters |language=en |volume=142 |issue=1–2 |pages=43–57 |doi=10.1016/0012-821X(96)00069-6|bibcode=1996E&PSL.142...43L |url-access=subscription }}</ref> forming a flat [[floodplain]] where a number of rivers converged. This region may have served as an environmental refuge for early humans during periodic hyperarid climate oscillations. The modern marine Gulf was formed when sea level rose during the early [[Holocene]], from around 12,000 to 6,000 years ago. The flooding of the Gulf may have stimulated the development of [[Neolithic]] farming cultures in regions of the Middle East adjacent to the Gulf.<ref name="Rose2010">{{Cite journal |last=Rose |first=Jeffrey I. |date=December 2010 |title=New Light on Human Prehistory in the Arabo-Persian Gulf Oasis |url=https://www.journals.uchicago.edu/doi/10.1086/657397 |journal=Current Anthropology |language=en |volume=51 |issue=6 |pages=849–883 |doi=10.1086/657397 |s2cid=144935980 |issn=0011-3204|url-access=subscription }}</ref>[[File:NE 565ad.jpg|upright=1.25|thumb|Map depicting extent of early civilizations around the Persian Gulf, including Lackhmids and Sassanids.]]

For most of the early history of the settlements in the Persian Gulf, the southern shores were ruled by a series of nomadic tribes. During the end of the [[fourth millennium BC]], the southern part of the Persian Gulf was dominated by the [[Dilmun]] civilization. For a long time, the most important settlement on the southern coast of the Persian Gulf was [[Gerrha]]. In the second century [[Lakhmids|the Lakhum tribe]], who lived in what is now Yemen, migrated north and founded the [[Lakhmid|Lakhmid Kingdom]] along the southern coast. Occasional ancient battles took place along the Persian Gulf coastlines, between the Sassanid Persian empire and the Lakhmid Kingdom, the most prominent of which was the invasion led by [[Shapur II]] against the Lakhmids, leading to Lakhmids' defeat, and advancement into Arabia, along the southern shorelines.<ref>{{cite book|url=https://books.google.com/books?id=sP_hVmik-QYC&pg=PA179|title=E.J.

The Achaemenid high naval command had established major naval bases located along Shatt al-Arab river, Bahrain, Oman, and Yemen.

Following the fall of Achaemenid Empire, and after the fall of the [[Parthian Empire]], the [[Sassanid Empire]] ruled the northern half and at times the southern half of the Persian Gulf. The Persian Gulf, along with the [[Silk Road]], were important trade routes in the Sassanid Empire. Many of the trading ports of the Persian empires were located in or around Persian Gulf. [[Siraf]], an ancient Sassanid port that was located on the northern shore of the Persian Gulf, located in what is now the Iranian province of [[Bushehr]], is an example of such commercial port. Siraf, was also significant in that it had a flourishing commercial trade with China by the fourth century, having first established connection with the far east in 185 AD.<ref>{{cite web|url=http://www.bips.ac.uk/sites/siraf|title=Siraf|author=British Institute of Persian Studies|access-date=2010-11-24|archive-url=https://web.archive.org/web/20110716111330/http://www.bips.ac.uk/sites/siraf|archive-date=2011-07-16|url-status=live}}</ref>

==Wildlife==
{{see also|Gulf of Oman desert and semi-desert}}
The wildlife of the Persian Gulf is diverse, and entirely unique because of the Persian Gulf's geographic distribution and its isolation from the international waters only breached by the narrow [[Strait of Hormuz]]. The Persian Gulf has hosted some of the most magnificent marine fauna and flora, some of which are near [[Local extinction|extirpation]] or at serious environmental risk. From corals, to [[dugong]]s, Persian Gulf is a diverse cradle for many species who depend on each other for survival. However, the Persian Gulf is not as biologically diverse as the [[Red Sea]].<ref>Pernetta, John. (2004). Guide to the Oceans. Buffalo, NY: Firefly Books, Inc. p. 205. {{ISBN|978-1-55297-942-6}}.</ref>
 
Overall, the wildlife of the Persian Gulf is endangered from both global factors, and regional, local negligence. Most pollution is from ships; land generated pollution counts as the second most common source of pollution.<ref>{{cite web|url=http://www.parstimes.com/environment/pg_pollution.html|title=Pollution in Persian Gulf|author=Morteza Aminmansour/Pars Times|access-date=2010-11-24|archive-url=https://web.archive.org/web/20101126155602/http://parstimes.com/environment/pg_pollution.html|archive-date=2010-11-26|url-status=live}}</ref>

One of the more unusual marine mammals living in the Persian Gulf is the [[dugong]] (''Dugong dugon''). Also called "sea cows", for their grazing habits and mild manner resembling livestock, dugongs have a life expectancy similar to that of humans and they can grow up to {{convert|3|m|abbr=off}} in length. These gentle mammals feed on sea grass and are closer relatives of certain land mammals than are [[dolphins]] and [[whales]].<ref name=dugong>{{cite web|url=http://www.american.edu/TED/persian.htm |title=Case Study |publisher=American.edu |access-date=2009-07-10 |archive-url=https://web.archive.org/web/20090624134459/http://www1.american.edu/TED/persian.htm |archive-date=24 June 2009}}</ref> Their simple grass diet is negatively affected by new developments along the Persian Gulf coastline, particularly the construction of artificial islands by Arab states and pollution from [[Gulf War oil spill|oil spills caused during the "Persian Gulf war"]] and various other natural and artificial causes. Uncontrolled hunting has also had a negative impact on the survival of dugongs.<ref name=dugong/> After Australian waters, which are estimated to contain some 80,000 dugong inhabitants, the waters off Qatar, Bahrain, UAE, and Saudi Arabia make the Persian Gulf the second most important habitat for the species, hosting some 7,500 remaining dugongs. However, the current number of dugongs is dwindling, and it is not clear how many are currently alive or what their reproductive trend is.<ref name=dugong/><ref>{{cite web |url=http://www.greenprophet.com/2010/03/dugong-mermaid-persian-gulf/ |title=Persian Gulf Mermaids Face Environmental Threats |publisher=Maurice Picow |date=2010-03-04 |access-date=2010-11-19 |archive-url=https://web.archive.org/web/20110114092625/http://www.greenprophet.com/2010/03/dugong-mermaid-persian-gulf/ |archive-date=2011-01-14 |url-status=live }}</ref> Ambitious and uncalculated construction schemes, political unrest, ever-present international conflict, the most lucrative world supply of oil, and the lack of cooperation between Arab states and Iran, have had a negative impact on the survival of many marine species, including dugongs.
 
===Birds===
[[File:Persian Gulf Near Hormuz Island.jpg|thumb|Birds in Persian Gulf Near Hormuz Island]]
The Persian Gulf is also home to many migratory and local birds. There is great variation in color, size, and type of the bird species that call the Persian Gulf home. Concerns regarding the endangerment of the ''kalbaensis'' subspecies of the [[collared kingfisher]]s were raised by conservationists over real estate development by the United Arab Emirates and Oman.<ref name=d/> Estimates from 2006 showed that only three viable nesting sites were available for this ancient bird, one located {{convert|80|mi|0|abbr=out}} from Dubai, and two smaller sites in Oman.<ref name=d/> Such real estate expansion could prove devastating to this subspecies. A UN plan to protect the mangroves as a biological reserve was ignored by the emirate of Sharjah, which allowed the dredging of a channel that bisects the wetland and construction of an adjacent concrete walkway.<ref name=d/> Environmental watchdogs in Arabia are few, and those that do advocate the wildlife are often silenced or ignored by developers of real estate many of whom have governmental connections.<ref name=d/>
 
Real estate development in the Persian Gulf by the United Arab Emirates and Oman also raised concerns that habitats of species such as the [[hawksbill turtle]], [[greater flamingo]], and [[booted warbler]] may be destroyed.<ref name=d/><ref>{{cite web|url=http://www.seaturtle.org/mtn/archives/mtn55/mtn55p26.shtml|title=Turtles Rehabilitated After Persian Gulf Oil Spills|author1=Tim Thomas|author2=Ian Robinson|name-list-style=amp|year=2001|access-date=2010-11-23|archive-url=https://archive.today/20120910183528/http://www.seaturtle.org/mtn/archives/mtn55/mtn55p26.shtml|archive-date=2012-09-10|url-status=live}}</ref> The dolphins that frequent the Persian Gulf in northern waters around Iran are also at risk. Recent statistics and observations show that dolphins are at danger of entrapment in purse [[seine fishing]] nets and exposure to chemical pollutants; perhaps the most alarming sign is the "mass suicides" committed by dolphins off Iran's [[Hormozgan]] province, which are not well understood, but are suspected to be linked with a deteriorating marine environment from water pollution from oil, sewage, and industrial run offs.<ref>{{cite web|title=Dolphins of Persian Gulf are in danger|author=Mandana Javidinejad|publisher=Payvand News Agency|year=2007|access-date=25 December 2010|url=http://www.payvand.com/news/07/sep/1339.html|archive-url=https://web.archive.org/web/20110629095910/http://www.payvand.com/news/07/sep/1339.html|archive-date=2011-06-29|url-status=live}}</ref><ref>{{cite web|title=Iran: Spill, Dolphin Deaths Spark Alarm At Persian Gulf Pollution|author=Vahid Sepehri|publisher=Radio Free Europe, Radio Liberty|date=3 October 2007|access-date=25 December 2010|url=http://www.rferl.org/content/article/1078857.html|archive-url=https://web.archive.org/web/20110114055950/http://www.rferl.org/content/article/1078857.html|archive-date=2011-01-14|url-status=live}}</ref>
 
A 2009 study of ten Iranian islands in the Persian Gulf recorded more than 100,000 breeding pairs of waterbirds from 11 species, including the Bridled Tern (Sterna anaethetus), Lesser Crested Tern (Thalasseus bengalensis), and Crab Plover (Dromas ardeola). These islands provide critical nesting habitat, and fluctuations in seabird populations have been proposed as biological indicators of regional ecological health.<ref name="Behrouzi2013">Behrouzi-Rad, B.

===Flora===
A great example of this [[symbiosis]] are the [[mangroves]] in the Persian Gulf, which require tidal flow and a combination of fresh and salt water for growth, and act as nurseries for many crabs, small fish, and insects; these fish and insects are the source of food for many of the marine birds that feed on them.<ref name=d>{{cite web|url=http://dsc.discovery.com/news/2006/07/03/gulfwildlife_pla.html?category=earth&guid=20060703160030 |title=Development in Persian Gulf Threatens Wildlife |access-date=2008-06-30 |author=Jim Krane |date=3 July 2006 |publisher=Discovery Channel |archive-url=https://web.archive.org/web/20060923035904/http://dsc.discovery.com/news/2006/07/03/gulfwildlife_pla.html?category=earth&guid=20060703160030 |archive-date=2006-09-23}}</ref> Mangroves are a diverse group of shrubs and trees belonging to the genus ''[[Avicennia]]'' or ''[[Rhizophora]]'' that flourish in the salt water shallows of the Persian Gulf, and are the most important habitats for small crustaceans that dwell in them. They are as crucial an indicator of biological health on the surface of the water, as the corals are to biological health of the Persian Gulf in deeper waters. Mangroves' ability to survive the salt water through intricate molecular mechanisms, their unique reproductive cycle, and their ability to grow in the most oxygen-deprived waters have allowed them extensive growth in hostile areas of the Persian Gulf.<ref>{{cite web|url=http://life.bio.sunysb.edu/marinebio/mangal.html|title=Mangals|author=SunySB|access-date=2010-11-23|archive-url=https://web.archive.org/web/20101206074225/http://life.bio.sunysb.edu/marinebio/mangal.html|archive-date=2010-12-06|url-status=live}}</ref><ref>{{cite journal |title=Expression of mangrove allene oxide cyclase enhances salt tolerance in Escherichia coli, yeast, and tobacco cells |journal=[[Plant and Cell Physiology]] |date=Fall 1980 |last1=Yamada |first1=Akiyo |last2=Saitoh |first2=Takeo |last3=Mimura |first3=Tetsuro |last4=Ozeki |first4=Yoshihiro |volume=43 |issue=8 |pages=903–910 |doi=10.1093/pcp/pcf108 |pmid=12198193 |doi-access=free }}</ref> However, with the advent of artificial island development, most of their habitat is destroyed, or occupied by man-made structures.

Large gas finds have also been made, with Qatar and Iran sharing a giant field across the territorial median line (North Field in the Qatari sector; South Pars Field in the Iranian sector). Using this gas, Qatar has built up a substantial [[liquefied natural gas]] (LNG) and petrochemical industry.
 
In 2002, the Persian Gulf nations of Bahrain, Iran, Iraq, Kuwait, Qatar, Saudi Arabia, and the UAE produced about 25% of the world's oil, held nearly two-thirds of the world's crude [[Oil and gas reserves and resource quantification|oil reserves]], and about 35% of the world's [[natural gas]] reserves.<ref>{{cite web|author=Persian Gulf Online|title=Persian Gulf Oil and Gas Exports Fact Sheet (U.S. Department of Energy)|url=http://www.persiangulfonline.org/interestgroups/oilfacts.htm|archive-url=https://web.archive.org/web/20090714233158/http://www.persiangulfonline.org/interestgroups/oilfacts.htm|archive-date=14 July 2009|access-date=4 March 2011}}</ref><ref>{{cite web|author=U.S. Energy Information Administration (EIA)|title=Persian Gulf Oil and Gas Export Fact Sheet|url=http://www.eia.doe.gov/cabs/pgulf2.html|archive-url=https://web.archive.org/web/20110102032341/http://www.eia.doe.gov/cabs/pgulf2.html|archive-date=2 January 2011|publisher=EIA/DOE (Energy Information Administration/Department of Energy)}}</ref> The oil-rich countries (excluding [[Iraq]]) that have a coastline on the Persian Gulf are referred to as the ''[[Arab states of the Persian Gulf|Persian Gulf States]]''. Iraq's egress to the Persian Gulf is narrow and easily blockaded, consisting of the marshy river delta of the [[Shatt al-Arab]], which carries the waters of the [[Euphrates]] and the [[Tigris]] rivers, where the east bank is held by Iran.
