What is the animal Lasiognathus known for?

Lasiognathus is a genus of deep-sea anglerfish that are known for their unusual lure apparatus.
They have a fishing rod-like structure on their head, called an illicium, that has a bioluminescent tip, called an esca, and large hooks, called denticles.
They use this apparatus to attract and catch prey in the dark depths of the ocean.
Lasiognathus has six species, each with different characteristics of their illicium and esca.
Some of them have very long illicia that can exceed their body length, while others have shorter ones.
Some of them have esca that resemble worms, while others have esca that look like fish.
Lasiognathus is also distinctive for having a huge upper jaw that can fold down to enclose the lower jaw.

What does the Lasiognathus look like?

Lasiognathus is a genus of deep-sea anglerfish that has a large head and a slender body.

It has a lure apparatus on its forehead that consists of a fishing rod, a fishing line, a bait, and hooks.

The bait is a bioluminescent organ that attracts prey in the dark.

The fishing rod is a bone that projects from the head, the fishing line is a modified fin ray, and the hooks are large skin teeth.

The lure apparatus can vary in size and shape among different species of Lasiognathus.

Some have a short lure that reaches the middle of the body, while others have a long lure that exceeds the body length.

Lasiognathus also has a huge upper jaw that can fold down to enclose the lower jaw.

The upper jaw has hinged bones that allow it to open wide and swallow large prey.

Lasiognathus lives in the Atlantic and Pacific Oceans, at depths of up to 4,000 meters.
