Ophiocoma erinaceus is an echinoderm, more specifically a brittle star of the Ophiocomidae family. [1]

Description

Ophiocoma erinaceus is black with red tube feet. [1] [2] On the arm segments, there are three arm spines on one segment while the other has four. The next segment occurs in reverse order. [3] In Hawaii, it is the largest brittle star, with sizes of the arms going up to 5 ½ inches, and the disk can be about 1 inch in diameter. [1]

Distribution and habitat

Ophiocoma erinaceus is distributed within the Indo-Pacific oceans and can be found under rocks and stones. [1]

Human uses

The saponin and antioxidants Ophiocoma erinaceus produces is the subject of interest to researchers as it has been studied for medical research. [4] It has been observed that the saponin extracted from Ophiocoma erinaceus can decrease and inhibit the growth of HeLa human cervix cancer cells. [4]
