Overview

Comprehensive Description

Biology/Natural History: This species is said to feed on compound ascidians and on bryozoans such as Alcyonidium spp. It lays its egs in whorled ribbons of capsules which stand on edge on the rocks they are laid on. The eggs are white to cream colored.

Kozloff's key states that there is no yellow band around the margin of this distinctive species. This individual seems to have at least a partial yellow band around the margin so it may be another color phase of this variable species or it could possibly be a hybrid with a related species such as A. hudsoni, which does have such a band.
