One of the frames from the video on predation on the Psolus chitinoides
Predation of a Psolus chitinoides by a sea star is examined and discussed by Laura and Nadege. The stomach of the sea star surrounds the sea cucumber and the soft neck and mouth of Psolus is well inside the cavity of the sea
We see these occasionally at Race Rocks in the subtidal areas.Their favorite prey are various species of sea cucumber. Their puffy arms distinguish them from other orange stars. They can grow to 40 cm. across.

 The Race Rocks taxonomy is a collaborative venture originally started with the Biology and Environmental Systems students of Lester Pearson College UWC. It now also has contributions added by Faculty, Staff, Volunteers and Observers on the remote control webcams.
