Trapania euryeia is known from the Marshalls by about 14 specimens observed at Enewetak and Kwajalein Atolls. All but one were found on under rocks on lagoon pinnacles or on the seaward reef at depths of 6 to 18 meters. The exception came from a depth of 1 meter from a man-made quarry on the Enewetak Island reef flat. Sizes ranged from 3 to 10mm. The specimen in the two photos below came from a Kwajalein Atoll lagoon pinnacle under a dead, sponge-encrusted fungiid coral at a depth of about 7m on 6 June 2010.
The remaining animals were all photographed at Enewetak Atoll between 1981 and 1983.
The specimen below was unusual in that it had slightly orange colored oral tentacles.
The individual in the photo below had more brown pigment that most of the others.
This photo contains two different species of Trapania found under adjacent rocks. The larger is a T. euryeia with mostly white pigment. The smaller is Trapania squama.
