Axoniderma corona

Axoniderma corona is a species of demosponge in the family Cladorhizidae. It is known from type specimens found near the Aleutian Islands.

Etymology
The generic name is derived from the Ancient Greek ἄξων (áxōn), "wheel", and δέρμα (dérma), "skin". The specific epithet comes from the Latin corona, meaning "crown", in reference to the fact that the species' distal appendages resemble a crown.
