Project Description

The gray brittle star (Ophiura luetkenii) can move quickly out of the way towards safety if a predator sea star is sensed.  This species of brittle star is often found on sandy or silty substrates, and this particular one was noticed resting on a piece of kelp on the ocean floor.  The gray brittle star is medium sized with a brown or gray body that often has white spots, as well as banding on the arms.  This brittle star can grow to around 7 inches (18 cm) across, with a range from northern Alaska to northern Mexico.
