Anglerfish occur worldwide. Some are pelagic (dwelling away from the sea floor), while others are benthic (dwelling close to the sea floor). Some live in the deep sea (such as the Ceratiidae), while others live on the continental shelf, such as the frogfishes and the Lophiidae (monkfish or goosefish).
The deep sea anglerfish lives close to the seafloor and is notable for their lure, that produces its own light, to attract prey. Learn more about this deep sea dweller.
There are over 200 species of deep-sea anglerfish. From the recognizable toothy jaws of the black seadevil to the bottom-dwelling sea toads, deep-sea anglerfish come in all sorts of shapes and sizes.
All anglerfish are carnivorous, so their adaptations all help them catch prey. But there are differences detween the surface living and deep-sea species. Deep-sea anglerfish that live close to the sea floor are flattened dorso-ventrally, like a plate on a table, with the mouth facing upwards.
But no matter what it looks like, any deep-sea anglerfish is a small ocean-dwelling creature’s worst nightmare. Luring in the unlucky. Anglerfish are named for the glowing lure they...
Discover the incredible anglerfish, denizen of the ocean's deep, lightless realms. Learn how these predators attract their victims with bits of luminous flesh.
The deep-sea anglers comprise 11 families of the superfamily Ceratioidea. Unlike other anglers, they lack pelvic fins, and they swim about, though feebly, rather than live on the bottom. They may be up to 1.2 metres (4 feet) long, but most are much smaller. Only the females have a “fishing rod.”
Deep-sea anglerfish are strange and elusive creatures that are very rarely observed in their natural habitat. Fewer than half a dozen have ever been captured on film or video by deep diving...
In deep-sea anglerfish, the lure glows a faint blue light. Created by symbiotic glowing bacteria called Photobacterium take up residence in the anglerfish’s esca, and in exchange, the bacteria gains protection and nutrients as the fish swims along.
The anglerfish is one of the most famous deep-sea animals. This bulbous beast has a “fishing pole” projecting from its head. The first ray of its dorsal fin is modified into a filament (called an illicium) with a sac of glowing bacteria at the tip (called an esca).
