The Sargasso fish ( Histrio histrio ), Sargassum frogfish or Sargassum toad fish belong to the group of frogfish . The genus Histrio is monotypical and contains only this single species .
distribution
It lives in drifting brown algae of the genus Sargassum on the surface of the tropical and subtropical Atlantic and Indo-Pacific . Since it is dependent on the Tange, it can be driven far out of its range. Sargasso fish, for example, were found off the coast of northern Norway and drifted by the Gulf Stream .
Appearance
Sargasso fish, like other frogfish, have a plump body that is compressed at the sides. It is covered by numerous outgrowths that perfectly camouflage the fish between the rods. The color is mottled, light brown and ocher. The pectoral and ventral fins are similar to hands. With them the animal can hold on to the rods. Sargasso fish grow to be 15 centimeters long. Endangered Sargasso fish can pump themselves up like puffer fish by swallowing water.
The Antennariidae are known to reach the fastest snapping speed of all fish when they eat: opening their mouths to snap a suck takes only 12 milliseconds.
food
Crustaceans, small fish, cannibalism is said to occur occasionally.
Multiplication
Sargasso fish spawn at night. The couple leaves the protective seaweed and swims together to the surface of the water, where they release sperm and eggs. The eggs form a rolled-up ribbon that, once swollen, can be 6 to 8 inches wide and 75 inches long. The larvae hatch after four to five days and swim free after eleven days when the yolk sac is used up. Sargasso fish have also spawned in the aquarium.
