Info

Gymnanthenea laevis H.L. Clark, 1938

Gymnanthenea laevis is a starfish that varies in color.The colors are usually brown or gray speckled, sometimes with orange arm tips, and sometimes bright orange specimens can also be found

This starfish usually has five long arms with rounded tips, but exceptions prove the rule. The starfish has large, block-like, wavy plates with large pedicellaria and many spiny bumps along the arms.The upper side has many spiny protuberances, sometimes with very large, flat, plate-like spines.

The underside of Gymnanthenea laevis is pale and usually without pattern.Each plate on the underside has a two-shelled pedicellaria, and the tube feet with suction cups are pale.

Large specimens can pinch your fingers when they hold on, as they have large pinching structures.

Etymology: The species name “laevis” means smooth, even, hairless or bristle-free, which does not correspond to the description.
We were unable to determine the reason for the choice of the species name.
