Fin's Fish Guide
The Opah (Lampris guttatus) is a saltwater fish of the family Lampridae that grows up to 200 cm.
Description
The opah is a large, disc-shaped ocean fish (Lampridae). The species has a deep, strongly laterally compressed, blue-silvery body densely studded with white spots and bright-red fins and lips. Notably it is partly warm-blooded: by retaining heat from its muscles via the gills it keeps its body warmer than the surrounding water, making it an active hunter in cold deep water. It lives solitarily, epi- to mesopelagically in the open ocean, and feeds on midwater fishes and squid. The species is harmless to humans.
