Aluterus monoceros (Linnaeus, 1758)
Unicorn filefish, 76.2cm

We saw only about five of these at Kwajalein, and only one full adult, which we did not photograph. The adult we saw was in the superstructure of a lagoon bottom shipwreck in about 35m of water. Four additional adults were observed near the marker buoy line on a lagoon shipwreck by Jay Lord, who took the first photo below. Three small to medium sized individuals that we saw were also at different times hanging around buoy lines marking lagoon shipwrecks. One more juvenile was spotted amid drifting debris near the surface of the water.

The next two photos show a medium sized individual. These and the juvenile photos are low resolution captures from old analog video, and hence are not very sharp.

The next two show one of the smaller juveniles.
