Mahi-mahi

Mahi-mahi (Coryphaena hippurus), or common dolphinfish, is a large, fast-swimming marine fish found in warm ocean waters. Its firm flesh is widely eaten.

Coryphaenidae: Coryphaenidae is a family of fast-swimming marine fishes containing the genus Coryphaena. Mahi-mahi belongs to this small family, whose other living species is the pompano dolphinfish.
Ectothermy: Ectothermy is a mode of temperature regulation in which body temperature depends largely on external conditions. Mahi-mahi’s activity and distribution are tied to the warm temperatures of surface waters.
Commercial fishing: Commercial fishing is the capture of wild aquatic animals for sale and profit. Mahi-mahi supports commercial fisheries across tropical and subtropical oceans.
Dolphin: Dolphins are aquatic mammals in the infraorder Cetacea, distinct from fishes. Despite its English name dolphinfish, mahi-mahi is a fish, not a dolphin.
Pompano dolphinfish: Pompano dolphinfish (Coryphaena equiselis) is a smaller species in the same genus as mahi-mahi. It is mahi-mahi’s closest living relative and is distinguished by its smaller size.
Ram ventilation: Ram ventilation is the flow of water over fish gills created by swimming with the mouth open. As a fast swimmer, mahi-mahi can move water across its gills while moving forward.
Longline fishing: Longline fishing uses a main line bearing many baited hooks to catch fish. Longlines are one method used to catch mahi-mahi, often alongside tuna and other pelagic species.
Dolphinfish: Dolphinfish is a common name for fishes of the genus Coryphaena. The name is often used for mahi-mahi but can be confused with the marine mammal dolphin.
Pelagic zone: The pelagic zone is the open-water region of the ocean, away from the seafloor and shore. Mahi-mahi spends its life in open water rather than on the seabed.
Predation: Predation is an interaction in which one organism captures and consumes another. Mahi-mahi’s rapid pursuit of smaller animals makes predation central to its feeding ecology.
