Morphology

tusk + shell

The compound is directly compositional: a 'tusk shell' is a shell that resembles a tusk (long, tapered, tubular), so a learner who knows 'tusk' and 'shell' can infer the shape and likely referent. Although it's a specialized zoological name, the noun+noun formation follows normal English patterns and is predictable from the parts.

Etymology

Tusk shell gets its name from the long, thin shell that looks like a tusk, a big animal 'tooth'. So the name simply describes the small sea animal with a tooth-like shell.
