Project Description

This giant nudibranch (Dendronotus iris) was on the hunt for tube-dwelling anemones.  When an anemone is sensed just ahead of a giant nudibranch, the hunter raises the front of its body up high and does a cobra strike downward snipping off a mouthful of tentacles as the anemone retreats into its home.  There is a great variance in colour between individuals of this species with some almost white, and others different shades of orange.  There is also a white line around the edge of the foot.  The giant nudibranch can grow to 12 inches (30 cm) long, with a range from northern Alaska to northern Mexico.
