What term describes a juvenile oyster that has recently settled on a substrate?

Explanation:
Spat refers to the juvenile oyster that has recently settled on a substrate. After the oyster completes the free-swimming larval stages, it attaches to a surface and becomes spat, the early attached juvenile that will grow into an adult. This term is specifically used for the settled, post-larval stage. The other terms describe different things: a clutch is a batch of eggs laid by a female, a larva is the planktonic stage before settlement, and byssus refers to the thread-like structures some bivalves use to attach to surfaces.
