Thuridilla carlsoni is relatively common in the Marshalls with more than 60 specimens observed at Enewetak and Kwajalein Atolls, and at least one more at Wotje Atoll. We have also seen the species in Hawaii. In the Marshalls, they live on shallow lagoon reefs, pinnacles, and the seaward reef and are usually found crawling about in the open on dead coral or algae. Lengths of 16 specimens ranged from 11 to 30mm.
