Seastars
Two unknown species of seastars (Phylum Echinodermata, Class Asteroidea) have been photographed at Axial.
Unknown Seastar 1 (Mediaster sp.?)
This bat-star (shown to the left of a brittle star) has been observed on several occassions, living on the lava rocks on Axial's caldera. It has characteristics similar to members of the Genus Mediaster, which are common in the Pacific.
Unknown Seastar 2 (Zoroaster sp.?)
This species is also fairly common, seen lounging on the basaltic lavas of Axial. Its long, spiny arms are similar to those seastars in the Zoroaster Genus.
