Image Gallery: Whalefishes

Whalefishes are deepsea fishes with a remarkable developmental story. What were previously recognized as three distinct families of deepsea fishes are in fact only one. The whalefishes (family Cetomimidae) are all female, the smaller bignose fishes (family Megalomycteridae) are all male and the bizarre tapetails (family Mirapinnidae) are larvae.  Interestingly, the males and females live in the deepsea but the juveniles inhabit shallow waters.
