Heliaster microbrachius is a species of Asteroidea (sea stars) in the family Heliasteridae.[1][2][3]

Description[]

Heliaster microbrachius can reach a diameter of 60–125 millimetres (2.4–4.9 in). The body consists of a disc with several rays. At the bottom of the body there is a mouth opening. These sea stars have a very large disc, somewhat elevated, with more or less flattened rays. Abactinal spines are very numerous, small, more or less cylindrical. Color of abactinal surface may be purplish or grayish-black, with deep yellow or whitish spines. The actinal surface is whitish, yellowish, or brownish, with pedicels much darker than spines.[4] These sea stars can regenerate lost or damaged parts of their body.
