Top 5 strangest animals found in the depths of the sea

The coffin fish (Chaunax endeavouri) is a species of abyssal fish belonging to the Chaunacidae family. This fascinating creature is found in the depths of the ocean, specifically in the southwestern Pacific region, including the waters around Australia and New Zealand.

 The name 'coffin fish' is due to its unique and peculiar appearance. These fish have flattened bodies, with a large head and small eyes. One of the most notable features of the coffin fish is its elongated and extendable lower jaw, which allows it to catch prey in the dark depths where it lives.

 Their coloration varies, but they are generally in dark or brownish tones, which help them blend into their habitat. Additionally, their skin is covered in small rough scales, giving them a rough and rugged appearance.

 The coffin fish primarily feeds on small marine invertebrates, such as shrimps and crabs, which it captures using its extendable jaw. Due to its deep-sea lifestyle, where light is scarce, this fish has luminous organs on its skin that emit a soft bioluminescence, aiding in attracting its prey.

The viperfish, also known as the Pacific viperfish or Chauliodus sloani, is a species of abyssal fish that inhabits the depths of the Pacific Ocean. It is a member of the Stomiidae family, which includes numerous species adapted to life in the darkest and coldest zones of the ocean.

 The viperfish has a very peculiar and distinctive appearance. It possesses a slim and elongated body, with a long jaw filled with sharp and pointed teeth. These teeth are so large in relation to its body that they resemble fangs, which has earned it the name 'viper.'

 The coloration of the viperfish is generally black or dark brown, which helps it blend into the depths where it lives. Its skin is thin and translucent, allowing the bioluminescent light produced by its internal luminous organs to shine through. This bioluminescence enables the viperfish to attract prey and potential mates, as well as confuse predators.

 The viperfish is a fierce predator that feeds on other small to medium-sized fish and marine organisms. Its extendable jaw and sharp teeth allow it to capture and hold onto its prey, even when they are larger than itself. Additionally, its stomach is highly elastic, allowing it to swallow prey that has a considerable size in comparison to its own body.

The frilled shark (Chlamydoselachus anguineus), also known as the frill shark or quilted shark, is a species of primitive shark belonging to the Chlamydoselachidae family. It is considered one of the most unusual and primitive sharks that exist today.

The frilled shark has a unique and distinctive appearance. Its body is long and slender, with an elongated head that resembles that of an eel. It lacks dorsal fins, and its caudal fin is very long and narrow, giving it a whip-like appearance. Its coloration is generally dark gray or brown, which allows it to camouflage in its deep-sea habitat.

This shark inhabits the depths of the ocean, usually at depths ranging from 600 to 1,200 meters, although it has also been found at greater depths. It is distributed in the cold and temperate waters of the Atlantic and Pacific Oceans.

The frilled shark primarily feeds on fish, cephalopods, and other marine invertebrates. Its jaw is long and equipped with small, sharp teeth, ideal for capturing prey in its dark and low-light environment.

The pelican eel, also known as the pelican eel or common pelican eel (Eurypharynx pelecanoides), is a species of abyssal fish found in the depths of the ocean. Despite its name, the pelican eel is not related to pelican birds but gets its name from its long, extendable jaw, resembling a pelican's beak.

The pelican eel is known for its unique appearance and special adaptations for life in the deep sea. It has a long and slender body that can reach lengths of up to 60 centimeters. Its head is small in comparison to its body, and its jaw is extraordinarily long and extendable. When at rest, the jaw folds up in a spiral, but it can quickly extend to capture its prey.

The pelican eel's jaw is filled with small, sharp, and pointed teeth that help grip captured prey. It primarily feeds on other fish and small marine organisms, which it swallows whole due to its flexible and elastic jaw

Anglerfish, scientifically known as Ceratiidae, is a family of abyssal fish belonging to the order Ceratioidei. These fish are notable for their unique appearance and adaptations to survive in the dark and cold depths of the ocean.

Physical Appearance: Anglerfish are known for their unusual appearance. They have small, laterally compressed bodies and are often covered in highly modified scales that give them a spiky and rough appearance. One of the most distinctive features of anglerfish is their modified spine-like fin, which extends from the top of their heads in a long and slender structure. This fin resembles a fishing lure, which is the characteristic that gives the family its common name, 'anglerfish.'

Bioluminescence: Anglerfish are bioluminescent, meaning they can produce their own light. They have luminous organs that allow them to generate flashes of light to attract prey or communicate in the dark depths of the ocean.

Habitat: These fish inhabit deep waters, typically at depths ranging from a few hundred meters to several thousand meters. They are found in all the world's oceans and are often located in the deepest areas of water where sunlight doesn't reach.

Feeding: Anglerfish are predators that primarily feed on small fish, invertebrates, and other marine organisms they encounter in the abyssal depths. They use their bioluminescent spine-like fin to lure prey towards their mouths, which are filled with sharp teeth.
