Description:
In the biological samples taken by the 5'x 5' Net micronekton tow undertaken for the EASTROPAC Expeditions (1967-1968), 28 “species” of Oegopsida cephalopods were identified. They are, Abralia andamaniea, Abraliopsis falco, A. ffinis, Pterygioteuthis giardi, Enoploteuthis n. spp. (2 spp.), Thelidioteuth/is alessandrini, Taningia danae, Onychoteutkis banksii, Onykia carribaea, Ctenopteryx siculus, Brachioteuthis riisei, Histioteuthis dofleini, H. meleagroteuthds, Bathyteuihis abyssicola, Neoteuthis sp., Ommastrephidae including Symplectoteuthis oualaniensis, Chiroteuthis veranyi, C. picteti, Mästigoteuthis sp., Cranchia scabra, Liocranchia reinhardti, Leachia schneehagenvi, Taonidium chuni, Phasmatopsis fisheri,
Helicocranchia pfefferi, Teuthowenia sp. and a Taoniinae gen. et sp. Among them, Liocranchia reinhardti was the most abundant occupying nearly one third (2,188 specimens of total 6,168 specimens) of all. Abraliopsis affinis stood the next (1,122 specimens). On the family base, Cranchiidae occupied more than half (53.82%) and Enoploteuthidae did about one third (33.95%) of all squids. More 22 species of Oegopsida have been known from the Eastern Tropical Pacific in the literature. Together with the EASTROPAC material, some 21% of Oegopsida known from the world oceans seems to be distributed in the Eastern Tropical Pacific.
