Family of ray-finned fishes
Caristiidae, the manefishes, are a family of scombriform ray-finned fishes which today includes 19 extant species distributed in four genera. Chalcidichthys malacapterygius and Absalomichthys velifer are extinct species in this family from the Upper Miocene of Southern California.
Biology
They are deep-sea marine fishes found in the mesopelagic zone [3] that eat siphonophores. An adult manefish is less than 25 cm in length and most of them are entirely black, which helps camouflage them from predators.[4]
