What are Cephalopods?

Octopuses, squid, cuttlefishes and nautiluses are marine molluscs, related to snails and slugs. They're found in the world's ocean and at all depths. They can be colorful or transparent and range in size from less than an inch to more than 50 feet. More than 800 species of cephalopods have been identified. These animals share a similar body plan that includes a head and eyes, a mantle and siphon, arms and tentacles, a beak and a file-like radula.
