Chascanopsetta prorigera is a species of pleuronectiformes in the of family Bothidae.[1] It was discovered by American ichthyologist Charles Henry Gilbert[2] in 1905 off the coast of Maui, Hawaii. They live in deep-sea, bathydemersal habitats, typically found at depths ranging from 267 to 400 meters.[3] They are 18–25 mm long on average but can get to be longer than 30 mm.[4]

Like most of this kind of fish, they are oviparous and start their life as a pelagic egg. After they hatch as larvae and grow to 10-25 mm they will undergo metamorphosis to become benthic juveniles and adults.[5] During metamorphosis the right eye migrates to the left side, the body flattens, and the fish transitions to a benthic lifestyle. They have an average life span of about 3-4 years and reach sexual maturity at about 1.44-1.5 years.[6][7] This fish has similar diets and habits to other flatfish when it comes to eating and hunting.[8][9][6]
