A squid's tentacles are homologous to the snail's foot.
The pen.
Their Dick
Snails have a shell, live on land. Squid live in the water, have tentacles, swim really well.
Squids are invertebrates, therefore they do not have spines. An earlier form of the squid had a shell, but this is obviously no longer present. However, a structure called the pen remains, part of the old shell. This is what helps the squid to maintain its structure.
Every mollusk except slugs, which have evolved to not need a shell, has a shell. Snails, clams and other bivalves have an external shell. Octopi, squid and cuttlefish have an internal shell.
The pen is a feather-shaped internal structure that supports the squid's mantle and serves as a site for muscle attachment. It is made of a chitin-like substance. It is the remnant of the squid's shell, so it is a vestigial structure.

No, a squid does not have a 'shell'. FALSE Squid actually are shellfish, they are cephalopods under the Mollusca Phylum also known as shellfish. Even though the squids shell is not visible, it has an external shell located in its mantle.
