What is the name of a terrestrial mollusc without shell?

Answer 1

Of the 100,000 different species of mollusk, a good many of them do, but some don't. Mollusca also includes the squid, the octopus and the slug. The first two have an internal structure that might be called an "internal shell" or the like. It should be noted that they completely decompose leaving only their beak. Slugs don't have shells or "hard" internal structures of any kind. A link can be found below to review the different creatures that are members of this phylum.

Answer 2

One kind of mollusc without a shell is called a slug. Some are the garden variety of slug, while certain species of slugs are aquatic and live in the sea.

The other well-known shell-less mollusc family is that of the squid and octopus, also known as Cephalopods.
