These little 3mm long animals appear to be Gastropteron minutum, but the ID is not certain. This pair in the first two rather fuzzy photos below was found on a lagoon reef at Enewetak Atoll, under dead coral at a depth of 5 meters.
The individual in the two photos below was found by Christina Sylvester in a Kwajalein reef quarry on 18 January 2015.
