Gymnothorax enigmaticus has been found at Kwajalein under rocks on lagoon pinnacles. The first shot matches an individual in Myers (1999).
The two photos by Stan Jazwinski match the adult Gymnothorax enigmaticus in Michael (1998).
The remaining ones look like younger specimens.
The very small one below is apparently a juvenile.
