Common Sea Star

Expert notes

Archaster typicus is a five-armed sea star commonly found resting on or half-buried in the sandy and muddy substrates of shallow Indo-Pacific coastal waters. — The image shows the oral (ventral) surface of a sea star with five tapering arms, distinct ambulacral grooves, and wide, granular marginal plates lacking the prominent fringe spines seen in similar genera like Astropecten, identifying it as the locally abundant Archaster typicus.
