Angler Fish - Glowing Deep Sea Monsters

Anglerfishes are paramount for their unusual predatory technique. Their first spine have been advanced into a fishing pole with a itsybitsy bate in the end. The fishing pole is as a matter of fact named "illicium" and the bate is named "esca". The esca is a fleshy increase found at the end of the illicium. When a predatory fish notices the esca, it thinks that it is a favorable prey. It swims close to the esca, and is rapidly overtaken by the Anglerfish before it gets a change to swallow the esca.

There are more than 200 known species of Anglerfish in the world, and more might be found in the hereafter since a lot of the Angler fish species inhabit great depths far down in the ocean where humans and their investigate equipment seldom venture. The Anglefish species are not contained in any special family or genera, they are instead spread out over several dissimilar families. They do however belong to the same order; Lophiiformes. (The order of the bony fishes.)

Angel fish species are paramount for their capability to kill and consume prey that is much larger than them selves. The ambush effect makes it possible for Angelfishes to kill large prey and their adaptable body makes it possible for them to swallow the catch. Their jaws can be distended to adapt huge prey and their thin and flexible bones make their stomach larger. The stomach of an Angler fish is very stretchy.

As mentioned above, a lot of the Anglerfish species dwell far down in the ocean. They inhabit aphotic zones to where the suns' light can not penetrate. A general esca is therefore invisible. The deep living Angler fish species have solved this by entering a symbiotic connection with a inescapable type of bacteria than produce light. The bacteria colonise the esca and make it glow in the dark, an example of so called bioluminescence. Bioluminescence is a tasteless feature in deep sea living organisms and other predatory fishes in the aphotic zone will therefore assume that the small esca is a favorable prey. The rest of the Angler fish is dark and can not be detected in the aphotic environment. The light from the esca is not strong enough to illuminate the body of the fish, nor is the light from other bioluminescent organisms. The Angler fish can therefore stay wholly private and ambush the unsuspecting predatory fish.

Deep sea Angler fish have advanced an unusual formula of reproduction. Once a male Anglerfish finds a female Anglerfish, he will never leave her. He attaches himself to her body using his sharp teeth and produces an enzyme that slowly allows him entrance to her blood stream. The two fishes will slowly melt together and the male will not hunt, he will get all the nourishment that he needs from the female Anglerfish. When she is ready to ovulate, the hormone levels in her blood will make the male produce sperm than can fertilize the eggs. In order for this formula to be successful, the female Anglerfishes are much larger than the male. When the males have attached themselves to a female, they will as a matter of fact deteriorate even further. One of the largest found female Anglerfishes was bigger than one yard (more than 90 centimeters). Some female Anglerfishes will allow several males to attach themselves to her.
