Unidentified shell

Does anyone have any ideas as to what the very spiky limpet or other mollusc in the bottom right of this picture is?

Probably Lottia scabra, the rough limpet. But it would be best to ask at iNaturalist, where that photo came from. Abductive (reasoning) 20:41, 13 April 2025 (UTC)[reply]
According to the linked source: Morro Bay, CA, USA, which falls within the species' range according to its article. {The poster formerly known as 87.81.230.195} 94.194.109.80 (talk) 07:26, 14 April 2025 (UTC)[reply]
