![]() They have 10 arms (two of which are much longer than the others for grasping prey), which are lined with rows of suckers. Most squid have a long, tube-shaped body with a small head. They can range from an inch to more than 65 feet in length. Squid come in a wide variety of sizes and appearances. Squid today are versatile creatures - they can make their homes in a variety of marine environments, from the deep sea to coastal surface waters. The earliest squid were most likely slow-moving creatures that lived in shallow waters. Today, only four remain - squid, cuttlefish, octopuses and nautiluses. So many different animal groups emerged during this period that scientists have termed it the "Cambrian explosion." Originally, thousands of species of cephalopods existed. The squid emerged during a particularly bountiful stage in the ecological timeline - 500 million years ago during the Cambrian period. Image used under GNU Free Documentation License Although countries around the world eat squid, they are especially popular in regions bordering the Mediterranean Sea, as well as in Japan. We most commonly enjoy them breaded and deep fried as calamari, or boiled and stewed as part of various seafood dishes. Because several types of fish have such a predilection for squid, they make excellent bait. Several animals and birds like to feast on squid, including the sperm whale, the grey-headed albatross, tuna, marlin, shark, seals and penguins. Cephalopods are divided even further into the eight-armed octopods (octopuses) and the 10-armed decapods (cuttlefish and squid).Ī variety of cephalopods in the subclass coleoida, which includes squid, octopuses, and cuttlefish, from Ernst Haeckel's "Art Forms of Nature" Eating Squid Squid are part of the class Cephalopoda (meaning "head-footed"), a group that also includes the octopus, cuttlefish and nautilus. ![]() Unlike other mollusks, which have a hard outer shell, squid have a soft outer body and an inner shell. Squid are actually mollusks, although they look much different from their relatives the gastropods ( snails), and bivalves ( clams). In this article, you'll get to know the often misunderstood squid, meet some of the unusual animals that are part of this species, and find out what happened when scientists finally came face-to-face with the mysterious giant squid. Squid are swift, agile and surprisingly intelligent creatures with brains closer in proportion to those of mammals than those of fish or reptiles. The giant squid's smaller cousins are better known, though no less fascinating. Few animals have inspired as much wonder and fear as the giant squid. One squeeze of this monstrous creature's enormous arms "could entangle a ship of five hundred tons and hurry it into the abyss of the ocean," Jules Verne wrote in his classic science-fiction novel, "20,000 Leagues under the Sea."Īlthough no such creature actually exists, the legends are likely based on sightings of giant squid, real but elusive creatures that can reach lengths of 60 feet with tentacles up to 30 feet long. More than 300 years ago, stories began circulating about a many-armed beast with tentacles as tall as a ship's mast living in the ocean depths.
