SCALLOP
A mollusk is a sea creature that lives within a shell. A cobra does not live in a shell.
An edible bivalve mollusk (family Pectinidae) with a ribbed fan-shaped shell. Scallops swim by rapidly opening and closing the shell valves.
The mollusk that moves by clapping its shell is the scallop. Scallops have a unique ability to swim short distances by rapidly opening and closing their shells, which expels water and propels them forward. This method of movement helps them escape predators and navigate their environment.
the function of the its shell is to protect the mollusk's very vulnerable and sensitive organs.
THey use a shell
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.

A shell
A cat's eye shell has a smooth, rounded shape with a spiral structure that helps protect the soft body of the mollusk inside. The shell also features a wide opening to allow the head and foot of the mollusk to extend out for feeding and movement. Additionally, the glossy appearance and unique patterns on the shell may provide camouflage and protection from predators.
