Marshall IslandsTriplefins (Trypterygiidae)

The triplefins are small, goby-like bottom dwellers characterized by having three separate dorsal fins. We suspect there are many more species in the Marshall Islands than this page covers. Unless otherwise noted, sizes given are maximum sizes for the species listed in Fishbase, not necessarily the size of the figured specimen.
