Mahi-mahi

Coryphaena hippurus

Also calledCommon dolphinfish · Dorado (Spanish) · Lampuka (Maltese) · Shiira (Japanese) · Ikan lemadang (Malay)

A blazing gold, green and blue surface hunter that grows astonishingly fast, reaching adulthood in months. Bulls develop a tall, square forehead; the colours fade to grey within minutes of death.

The mahi-mahi, common dolphinfish, dolphinfish, dolphin or dorado is a surface-dwelling ray-finned fish found in off-shore temperate, tropical, and subtropical waters worldwide. It is one of two members of the family Coryphaenidae, the other being the pompano dolphinfish. These fish are most commonly found in the waters around the Gulf of Mexico, Costa Rica, Hawaii, and the Indian Ocean. In Italy it is called corifena, lampuga or pesce capone, and has even given its name to the caponata though eggplant has now taken the place of the fish. Wikipedia

§1

What it can do

  1. iOne of the fastest-growing fishes, maturing at 4–5 months
  2. iiChanges colour rapidly, flashing bars and spots while hunting
  3. iiiGathers under floating sargassum, logs and debris to hunt
  4. ivLeaps clear of the water chasing flying fish

In the field

Field marks

  • aLong dorsal fin running from the head almost to the tail
  • bBrilliant golden sides, blue-green back and scattered blue spots
  • cMales with a steep, blunt forehead; females rounded
  • dDeeply forked tail
Not to be confused with
Pompano dolphinfish (C. equiselis) is smaller with a squarer tooth patch on the tongue and fewer dorsal rays (48–55 vs 58–66). Not related to dolphins (mammals).
Where to see it
Sargassum lines off Florida and the Bahamas, Costa Rica, Hawaii, Malta (autumn lampuka fishery)
When
Year-round in tropics; Malta Aug–Dec
§3

Life & habits

Diet
Flying fish, juvenile tunas, squid, crustaceans
Habitat
Warm surface waters, often near floating objects and sargassum
Size
Commonly 1 m; up to ~2 m and 40 kg
Lifespan
Usually under 4–5 years

Travels in small schools that follow drifting objects across the open ocean; pairs often stay together and a hooked fish is often followed by its mate.

In the old herbals & bestiaries

Woodcuts and engravings matched from the Source Library’s scanned books by name. Plates marked “relative” show a close kin rather than this exact species. Click a plate to read the page it came from, with translation.

§7

Marginalia

Maltese fishers have caught lampuki under floating palm-frond rafts (kannizzati) for centuries, a technique that predates modern fish aggregating devices; 'mahi-mahi' is Hawaiian for 'very strong'.

Curiosity

Its brilliant colours are produced by chromatophores and iridophores that collapse at death, turning the fish dull grey within minutes.
