We found these only on the shallow reefs at Kewalo Basin and Hauula, Oahu, but in both places they were plentiful. At Kewalo, it was the most common species encountered, with 239 specimens counted in approximately 23 hours of snorkeling on this .5 to 1.5m deep reef. On a recent trip there (30 March 2009), I found the area had changed after a new sea wall was built, and I saw no Melibe.
Egg masses can be seen to the right of the specimen below.
