Ecology Summary - Hexanchus vitulus

言語:

主な参照	Ebert, D.A., S. Fowler and M. Dando, 2021
意見	Found on continental and insular slopes. Feeds mainly on bony fishes and cephalopods, sometimes on crustaceans. It was reported that there is likely some stratification of the distribution by size, presumably with larger individuals present in deeper waters (mostly adult captured in the Bahamas at an average depth of 639.5 m) than the juveniles (< 350 m in Belize and northern Gulf of Mexico). Resource and habitat partitioning between juvenile and much larger adult bluntnose sixgill sharks has been suggested as predation avoidance (Ref. 117400).
