cuttlefish

noun

Etymology: From cuttle + fish.

1. Any squid-like cephalopods (marine mollusks) of the order Sepiida that have eight arms, two retractable tentacles, and a calcareous internal shell, and can eject a dark ink when threatened.

   “Cuttle-fish, spiced oysters, sea hedge-hogs, and lobsters were among the ingredients of love-potions that reputed thaumaturgist Apuleius [...] was accused of have prepared in order to win the love of a widow.”

   “Fossilised ink sacs are more conclusively known from the extinct “soft-bodied” Coleoidea cephalopods in groups Belemitida (including belemnites with bullet-like internal skeletons commonly found as fossils) and Phragmoteuthida as well as from squid, octopus and cuttlefish fossils.”
