Squid

Squids are a large, diverse group of marine cephalopods. Like all cephalopods, squids are distinguished by having a distinct head, bilateral symmetry, a mantle, and tentacles with suckers; squid, like cuttlefish, have eight arms and two tentacles arranged in pairs. These are a type of muscular hydrostat. If cut off, the tentacles do not grow back[1]. Squids can blend in with their surroundings to avoid predators.

Squid are exclusively carnivorous, feeding on fish and other invertebrates. Squid usually have two elongated tentacles especially for the capture of food. They are voracious, fast-moving and fast-growing predators, and can be hugely abundant in productive seas. Most live for one year, dying after spawning, although some of the giant species may live for two years or more.
