- Echinoderms possess an unusual suite of appendages on their skeletons, which are used for movement, interaction, and defense. In addition to spines, urchins and sea stars both possess pedicellariae (singular pedicellaria) which are jaw-like structures often at the end of stalks.ocean.si.edu/ocean-life/invertebrates/echinoderms

Echinoderm - Wikipedia
Echinoderms evolved from animals with bilateral symmetry. Although adult echinoderms possess pentaradial symmetry, their larvae are ciliated, free-swimming organisms with bilateral symmetry. Later, during metamorphosis, the left side of the body grows at the expense of the right side, which is eventually absorbed. The left side then grows in a pentaradially symmetric fashion, in whi…
