Slugs and snails are mollusks, a similar group of animals guaranteeing shellfish, octopus, squid, and shellfishes. Many marine populations have plummeted over the past sixty years as oceans have become more polluted and less hospitable. The various taxa of land and sea gastropods with slug morphology occur within numerous higher taxonomic groups of shelled species; such independent slug taxa are not in general closely related to one another. But there is more than meets the eye. Male octopuses have a specialized arm (the hectocotylus) which transfers sperm to a female, whereas squid mate in large groups.

Octopus eyes protrude from the top of the head, bulging near the tentacles. The decollate snail (Rumina decollata) will capture and eat garden snails, and because of this it has sometimes been introduced as a biological pest control agent. Cephalopod means "head-feet."
