What Is a Dolphin Fish? 11 Fun Fish Facts

What is a dolphin fish look like

A dolphin fish, also known as mahi-mahi, is a constant in tropical waters and, dare we say it, on seafood menus. While the dolphin fish is not actually a dolphin, it is a large, strong, fish that has a dorsal fin, which may inspire some comparisons to dolphins. The dolphin fish, like dolphins, are predators, and mainly roam the seas in the Gulf of Mexico, the Caribbean, and Hawaii. The dolphin fish is a brightly colored, vibrant fish that is an important part of ocean ecosystems.

What Is a Dolphin Fish/Mahi-Mahi?

There are actually two species of dolphin fish: the common dolphin fish, scientific name Coryphaena hippurus, and the pompano dolphin fish, Coryphaena equiselis. The two species are very similar, but the pompano dolphin fish is a bit smaller. Both are referred to as mahi-mahi. For the sake of this article, we’ll be focusing on the common dolphin fish.

Physical Description

Dolphin fish are a large species of fish that have a single dorsal fin that extends from the head to the tail. Males’ heads are rounded to the point where they protrude out. Females’ heads are rounded and smooth. The dolphin fish is also a vibrant, brightly colored fish that is golden on the sides and brightly colored blue and green on its sides and back. Mahi mahi fish grow to be 2.5-4.5 feet long, and catches have been recorded from 15 pounds to over 40 pounds.

Habitat

Dolphin fish are found in the Indian, Pacific, and Atlantic Oceans in tropical and subtropical waters. They dwell in temperatures that are at least 90 degrees, usually on or near the equator. While mahi mahi fish are most common in and prefer tropical waters, they can also be found in cooler waters as far north as Massachusetts.

Dolphin fish stay near the surface of the water, and close to the shore. They can usually be found in depths up to 250 feet. Dolphin fish are especially prominent in the Caribbean and the Gulf of Mexico, where a majority of fishing takes place. The dolphin fish is also found in large numbers off the coast of Hawaii.

Life Cycle

Dolphin fish reproduce at a rapid rate. They are sometimes jokingly referred to as “the rabbits of the ocean” Dolphin fish reach maturity at 4-5 months old, and should definitely be fully mature by the time they’re a year old.

Female dolphin fish can lay 100,000-1,000,000 eggs at a time and can lay eggs 2-3 times per year. Dolphin fish don’t have strict migratory patterns. They usually swim north as waters warm, and populations in those northern areas peak around July.

The fish can live up to five years, but it’s rare for them to exceed four, and the average lifespan is estimated to be 2-3 years. They’re usually caught by fishermen or predators.

How Is a Dolphin Fish Different From a Dolphin?

Despite the name, dolphin fish and dolphins have virtually nothing in common, other than that they both swim. Is a dolphin a fish? No! The dolphin is a mammal, which is warm blooded, and has live births. The dolphin fish is a fish. Both animals do have a dorsal fin; the dolphin fish’s dorsal fin runs along most of its body, while the dolphin’s dorsal fin is in the center of its back.

It’s likely that the misnomer for the dolphin fish came from the old scientific naming and classification system. Previously, the dolphin fish was categorized in the “Dolfyn” family, instead of the Coryphaena family. The bottlenose dolphin is in the family Delphinidae. As you can see, the dolphin fish and dolphin are not in the same scientific family, or genus, which demonstrates their lack of relationship with one another.

Fishing and Conservation

The dolphin fish is sometimes called “a gift for fisherman” because they are near the coast, close to the surface, and the fish usually yields a lot of meat. The mahi mahi fish is not considered endangered, and is cited as an environmentally-friendly fish for consumption. Due to their rapid reproduction rate, the dolphin fish replaces its population quickly,

Though the dolphin fish is not in immediate danger of extinction or significant population decrease, like all ocean dwelling creatures, issues associated with climate change could impact the fish.

11 Dolphin Fish Fun Facts

The dolphin fish is a very fast swimmer, reaching speeds of up to 60 mph.

The name “mahi-mahi” literally means “strong strong” in Polynesian. The name originates from Hawaii, where the fish are prevalent

The fish is also called “dorado” in Spanish, a name that stems from its golden color.

Dolphin fish lose their golden hues once they leave the water, and eventually turn a silvery color

Dolphin fish eat crab, squid and other crustaceans, as well as on other fish, like mackerel.

Outside of the Caribbean, the United States is the largest consumer of dolphin fish

Dolphin fish do not raise their young. Once the eggs hatch, the young dolphinfish quickly band together in schools to help ensure survival.

The young fish, and smaller dolphin fish, travel in schools of anywhere from a handful of fish to up to fifty fish. Larger fish travel alone, or sometimes in pairs.

The main predators of dolphin fish are sharks, swordfish, marlins, birds, and of course, humans.

Dolphin fish are very strong, and are known for being difficult to catch on fishing lines.

The largest dolphin fish ever recorded was found on September 25th, 1976, weighing about 87 pounds.

E ven though they live in the ocean all of the time, dolphins are mammals, not fish. Also, dolphins are different than “dolphinfish,” which are also known as mahi-mahi.

Like every mammal, dolphins are warm blooded. Unlike fish, who breathe through gills, dolphins breathe air using lungs. Dolphins must make frequent trips to the surface of the water to catch a breath. The blowhole on top of a dolphin’s head acts as a “nose,” making it easy for the dolphin to surface for air.

Other characteristics of dolphins that make them mammals rather than fish are that they give birth to live young rather than laying eggs and they feed their young with milk. Also, like all mammals, dolphins even have a tiny amount of hair, right around the blowhole.

Whales and porpoises are also mammals. There are 75 species of dolphins, whales, and porpoises living in the ocean. They are the only mammals, other than manatees, that spend their entire lives in the water.

An area of Florida Keys National Marine Sanctuary is home to a resident group of bottlenose dolphins. Many businesses conduct dolphin tours in this area, which can stress the dolphins. To help reduce disruption to dolphins in the sanctuary, the Office of National Marine Sanctuaries, National Marine Fisheries Service, the Dolphin Ecology Project, and the Whale and Dolphin Conservation Society created the Dolphin SMART program. This program recognizes businesses that promote responsible viewing of wild dolphins.

The dolphin fish is not a dolphin. Unlike dolphins, which are mammals, dolphin fish are a type of ray-finned fish. The dolphin fish most likely got its confusing common name because it was previously classified in the genus Dolfyn. It also has a melon-shaped head, much like that of a true dolphin. In the modern classification system, the fish belongs to the genus Coryphaena.

If a restaurant menu includes “dolphin,” it’s referring to the dolphin fish, not the mammal. Some restaurants use the alternative names mahi-mahi and pompano to prevent confusion.

Description

There are two species of dolphin fish. The common dolphin fish (also known as mahi-mahi or dorado) is C. hippurus. The other species of dolphin fish is C. equiselis, which is also known as the pompano dolphin fish.

Both species in the genus Coryphaena have a compressed head and single dorsal fin running the full length of the body. Both the anal and caudal fins are sharply concave. A mature male (bull) has a prominent protruding forehead, while a female has a rounded head. Mature females are smaller than males. Their long, slender bodies are well-suited to fast swimming. Mahi-mahi swim up to 50 knots (92.6 kph or 57.5 mph).

Pompano dolphin fish are sometimes mistaken for juvenile common dolphin fish or mahi-mahi because they are small, reaching a maximum length of 127 centimeters (50 in). Pompano dolphin fish are bright blue-green with silver-gold sides. The fish fade in color to dull gray-green when they die.

A typical mahi-mahi reaches a length of one meter and a weight of 7 to 13 kg (15 to 29 lb), but fish over 18 kg (40 lb) have been caught. These fish are brilliantly colored in shades of blue, green, and gold. Pectoral fins are iridescent blue, the back is green and blue, while flanks are silvery-gold. Some individuals sport red spots. Out of water, the fish appears golden (giving rise to the name dorado). Upon death, color fades to yellowish-gray.

Distribution

Both species of dolphin fish are migratory. The common dolphin fish prefers coastal and open water from sea level to a depth of 85 meters in temperate, subtropical, and tropical oceans worldwide. The pompano dolphin fish range overlaps that of the common dolphin fish, but it usually lives in the open ocean and occurs as deep as 119 meters. The fish form schools and tend to congregate in seaweed and under floating objects, including buoys and boats.

Diet and Predators

Dolphin fish are carnivores that prey upon zooplankton, squid, crustaceans, and smaller fish. The fish is prey to other large oceanic predators, including billfish and sharks. Both species are important for commercial and sports fishing. The fish are generally considered safe to eat, but they are moderately contaminated with mercury and can serve as a vector for ciguatera poisoning.

Reproduction and Life Cycle

Dolphin fish grow and mature very quickly. Fish reach maturity between 4 and 5 months of age and start spawning when they reach a length of about 20 centimeters. Spawning occurs throughout the year when water currents are warm. Females spawn two to three times each year, producing 80,000 to a million eggs each time. Pompano dolphin fish have a life span of up to 3 to 4 years, but most live less than 2 years. Mahi-mahi live up to 5 years, but rarely exceed 4 years.

Conservation Status

Both the common dolphin fish and pompano dolphin fish are categorized as “least concern” on the IUCN Red List. Its population is stable. However, the fish face threats from declining habitat quality. The species has high commercial value and is extensively harvested. Many countries have imposed bag limits and size limits to support sustainable fishing.
