Marshall Islands Emperors (Lethrinidae)

Emperors, although in a different family, appear similar to some of the snappers. A few species are very common to abundant, while others are less common to rare. All are predators on either invertebrates or fish, and some of the larger species may be ciguatoxic. Unless otherwise noted, sizes given are maximum sizes for the species listed in Fishbase, not necessarily the size of the figured specimen.
