So far we have seen at least 13 specimens, all but one at Enewetak Atoll, ranging in size from 7 to 32mm. All were white to pale pink, the larger ones with a tinge of purple around the anterior margin and on the tip of the tail. Rhinophores are orange and white; the first picture below is a large specimen that shows the colors well. On most, they were less distinct. All of the Enewetak specimens were found on lagoon pinnacles at depths of 10 to 15 meters, and most of the animals were on their prey species of sponge, shown in the second and third photos below.
This animal pulled away from its feeding position when disturbed. A moment before, it had its head in the hole right below it.
Surrounded by food!
The next four shots show the single animal so far found at Kwajalein Atoll. It was on a lagoon reef under a rock on its prey sponge at a depth of about 6m on 26 January 2009, and it measured about 15mm.
