Hexokelupha


 * Hexokelupha** (from Ancient Greek ἕξ (héx) 'six', and κέλυφος (kéluphos) 'shell') are invertebrate animals with a calcified shell that have 6-fold radial symmetry. There are a few classes that have forgone shells, but the vast majority grow a shell during or after their larval stage.


 * 1) Description

All hexokelupha exhibit 6-fold radial symmetry at some point during their lifespan, if only in the larval stage.
