What type of animal eats a squid?

Squid are marine cephalopods of the order Teuthida, which comprises around 300 species. Like all other cephalopods, squid have a distinct head, bilateral symmetry, a mantle, and arms. Squid, like cuttlefish, have eight arms arranged in pairs and two longer tentacles. (The only known exception is the bigfin squidgroup, which have ten very long, thin arms of equal length.)
