What is a shellfish with ten legs called?

There's no shellfish with ten legs. Here's why:

* Shellfish are a broad category that includes animals with shells, like clams, oysters, mussels, crabs, and lobsters.

* Legs are primarily associated with land-dwelling animals. Shellfish have appendages like claws, pincers, or legs for movement, but they are adapted to life underwater.

Here are some examples of common shellfish and their number of legs:

* Crabs: Have 10 legs (including their claws).

* Lobsters: Have 10 legs (including their claws).

* Shrimp: Have 10 legs (but they're very small and may be hard to see).

* Clams, Oysters, Mussels: These are bivalves and have no legs at all. They use their muscular foot to move.
