Where do Frogfish live?

Frogfish live mostly in reefs, though the Sargassum fish lives amongst the seaweed in the Sargasso Sea, a body of water in the North Atlantic Ocean. The fish completes its entire life cycle in this sea.

Are frogfish fossils still alive?

Few traces of frogfishes remain in the fossil record, though Antennarius monodi is known from the Miocene of Algeria and Eophryne barbuttii is known from the Eocene of Italy. Frogfishes live in the tropical and subtropical regions of the Atlantic and Pacific, as well as in the Indian Ocean and the Red Sea.

What is the habitat of a frogfish?

Frogfish are benthic inhabitants of shallow water (which means they live at the bottom in that shallow water). They live near the reef on debris and sandy areas covered with algae or remain hidden between corals and cracks. An exception is the pelagic frogfish of sargassum (Histrio histrio) that lives among the floating sargassum grass.

How big was the giant fish that once lived?

The most famous of these giants were the Jurassic Leedsichthys, which some reconstructions put at a whopping 70 feet long, and the Cretaceous Xiphactinus, which was “only” about 20 feet long but at least had a more robust diet (other fish, compared to Leedsichthys’ diet of plankton and krill).

What do frogfish eat in captivity?

When they are ready to strike, frogfish can strike very rapidly in under 6 milliseconds. These fish tend to feed on crustaceans and small fish, even other frogfish. In captivity you may need to use live feeder shrimp to entice these fish to eat and then transition them onto a diet of fresh and frozen meaty foods.

What has the frogfish evolved into?

When it comes to hunting, the frogfish has also evolved some neat tricks. Its forward dorsal fin has evolved from a fin into a fishing lure. The fin is now a long thin appendage that sticks out forward over the fish’s mouth.

What is the life cycle of a frogfish?

The frogfish’s life cycle and life span aren’t properly known yet. But since they’re fish they go through these stages. First they lay eggs then hatch as larval. Next they’ll become fries and after that juveniles. Finally they’ll become adults. When female frogfish becomes pregnant it’s abdomen will swell making her more buoyant.

Where do Frogfish live in the ocean?

Frogfish are tropical fish, they can be found in almost all tropical waters around the world. As a general rule, whenever you find a coral reef you will find some species of native frogfish. They are also considered like a prized species in some muck-diving, low visibility locations around the world.

Do living fossils have to be of the same species?

Living fossils commonly are of species-poor lineages, but they need not be. While the body plan of a living fossil remains superficially similar, it is never the same species as the remote ancestors it resembles, because genetic drift would inevitably change its chromosomal structure.

Are there any fossil remains of frogfish?

A cladogram of the evolution of tetrapods showing some of the best-known transitional fossils.

How does a frogfish attract its prey?

The most interesting aspect of the frogfish, apart from his prefect camouflage is the way he attracts his prey. Other fish lie in wait until the prey swims close to their mouth (lie-in-wait predation), but the frogfish (or anglerfish) lures the prey (fish, crustaceans) actively to where it can strike.

How does a frogfish kill its prey?

When the prey is within grasp the blitzkrieg attack takes place. The frogfish expands its oral cavity engulfing the prey with a reflex that instantly sucks it in by creating suction pressure inside the mouth. Taking no more than around 6/1,000 of a second, it is the fastest ‘gape and suck’ of any fish.

What is the function of a frogfish?

Frogfish have small, round gill openings behind their pectoral fins. With the exception of Butler’s frogfish and the rough anglerfish, frogfish use a gas bladder to control their buoyancy . The unusual appearance of the frogfish functions to conceal it from predators and sometimes to mimic a potential meal to its prey.

How does a frogfish move?

They also use jet propulsion, often used by younger frogfish. It is achieved by rhythmically gulping water and forcing it out through their gill openings, also called opercular openings, which lie behind their pectoral fins. The sargassum frogfish has adapted fins which can grab strands of sargassum, enabling it to “climb” through the seaweed.

What are the breeding habits of frogfishes?

There is not a great deal of research available regarding the breeding habits of frogfishes. Some species seem to be free spawners, with the female releasing eggs into the water column for the male to fertilize. Some species spawn over substrate and some of them actual guard their eggs until hatching, though most do not.

How do frogfish reproduce?

The reproductive behavior of the normally solitary frogfish is still not fully researched. Few observations in aquaria and even fewer from the wild have been made. Most species are free-spawning, with females laying the eggs in the water and males coming in behind to fertilize them.
