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 squid group, which have ten very long, thin arms of equal length.) Millions of years ago, prehistoric sea creatures swam Earth’s waters. Remains of these animals have been found near Australia, Germany, and in the Western Interior Seaway, a vast sea that once bisected North America.
