This northeast Pacific species is often found wedged in between rocks or crevices at the coast or on docks and can generally be identified by its orange bushy tentacles protruding above the substrate.
Their mouth and anus are at separate ends of the body resulting in a full digestive tract.
They live in rocky areas from the intertidal zone to a depth of 100 m, and are generally found wedged in crevices on docks or between rocks.
Since they have the ability to stay attached to a substrate, they tend to frequent areas with higher currents in order to avoid predation.
The fertilized eggs develop into non-feeding larvae that move slowly and settle near adults.
