Aquilonastra chantalae

Aquilonastra chantalae is a species of starfish from the family Asterinidae. Asterinid sea stars are typically quite small with an often pentagonal-shaped body, though there are exceptions. They are dorsally flattened and have short arms. The body's thin periphery is built up by very small marginal plates. One distinct characteristic of those in this family is the presence of an aboral face shaped by crescent-like plates.
