Bat Sea Star

Asterina miniata

ON EXHIBIT:  Boneless Beauties at Ocean Journey.

Bat Sea Star

This species is very common throughout its range and can vary greatly in color.  They typically have five arms, but specimens with four to nine arms are occasionally found as well. Sea stars eat by expelling their stomach and wrapping it around their food. Enzymes from the stomach tissue dissolve the food so it can be absorbed. Once finished, the stomach is taken back into the body.
