(Baughman 1955, Garrick 1964, Bass et al. 1975). However, the rarity of 'free-living' whale shark eggs, the extreme thinness and lack of tendrils on the only known case, the considerable yolk and partially developed gill sieve in the only known embryo, and the presence of umbilcal scars on larger free living specimens 55 cm long suggest the whale shark is ovoviviparous."}} Trovata la fonte (Sharks of the world
