The most terrible marine life in the world.

The ocean is a place full of infinite temptations and dangers, not only because of its rough waves, but also because of its dangerous creatures. Come with me to learn about the most horrible marine life in the world!

10, long-nosed silver shark (Lng rhinoceros)

Silver shark with long nose

Argyropoda

Cephalopods of cartilaginous fishes have 1 order, which has about 3 families, 6 genera and 30 species. The body length is 60 ~ 200 cm, and the female fish is bigger than the male fish. Stretch and flatten your body. The kiss is short and cone-shaped, or it protrudes from a sharp corner, or it protrudes flat and flat like a leaf hook, such as the black-line silver shark. A discoid beak with two jaws. The dorsal fin spine is active and vertical, and the second dorsal fin is low and slender, or short and triangular. The tail is curved, the lower lobe is larger than the upper lobe, and the axis of the tail vertebra is slightly upturned; Or round, the upper and lower leaves of caudal fin are about equal, and the axis of caudal vertebra is parallel; Or linear.

The body is smooth, and sometimes the larvae have shield scales on their heads and backs. In addition to flippers, the male body also has ventral flippers and frontal flippers. Eggs are large, cylindrical or oval. There are 3 ~ 3.5 spiral valves in the intestine. The annular vertebral artery of the heart has three rows of valves. The interval between gill filaments and gills is almost equal. There are 4 pairs of branchial cleft, which are covered by membranous branchial lid and have total branchial foramen on the back. Maxillary and skull healed. No vertebral body, no segmental contraction of spinal cord; The left and right halves of the belt are separated. No cloaca. In vivo fertilization. When breathing, the main stream of water mainly flows to the mouth through the nasolabial groove of the nostrils, and the mouth is generally closed. Swimming speed is slow, and it fluctuates by the back of the body, the second dorsal fin and the tail. The pectoral fin plays the role of propulsion and balance. Distributed in the Atlantic and Pacific oceans, inhabiting the deep sea above 2600 meters. Active at night, out of the water and die. Eat shellfish, crustaceans and small fish. Meat can be eaten and liver can be used as cod liver oil.

There are about 4 species of Vitidae, belonging to 1 genus, distributed in the coastal areas of South America, New Zealand, South Australia and South Africa.

There are 2 genera and more than 20 species of silver mackerel, which are distributed in the Pacific and Atlantic coasts. There are 2 genera and 4 species in China, distributed in East China Sea and South China Sea. There are 3 genera of Agkistrodon: about 2 species of Agkistrodon neoacutus, distributed in West Africa and south of Caribbean Sea; There are 6 species of Agkistrodon halys, and there are Pacific Agkistrodon halys in China.

9.vampire squid

Vampire squid

English name: vampire squid (vampire squid is a common name)

Latin scientific name: vampire

Size: about 6 inches (15.2 cm)

Habitat: tropical and temperate seas

Habitat depth:1800-3,500 feet (548.6-1066.8m).

This cephalopod, ghost octopus creature seems to have swam out of midnight science fiction movies. It has two big fins on its body, which look like two ears. It is shaped like jelly, more like jellyfish than squid or squid (originally not); Ghost octopus has big eyes. It is a small animal, only 6 inches long (15.2 cm), but its spherical eyes are as big as those of a big dog.

Ghost octopus is a luminous creature, and its body is covered with luminous organs, which makes it possible to light and extinguish itself at will. When it turns off the light emitter, it is completely invisible in the dark environment where it lives.

Unlike most squid, squid and octopus, ghost octopus has no ink sac. Their? Arm? There are fangs-shaped nails on the floor, which makes them named in English? Vampire squid. There is a couple? Arm? It can be stretched to twice the length of an animal's body. They use this pair of flexible tentacles to catch prey with other shorter tentacles. When in danger, the ghost octopus will turn all its tentacles up and cover them, forming a protective net with its nails.

As far as jelly-like creatures are concerned, ghost octopus can swim very fast, reaching two body lengths per second at the earliest, and this speed can be reached within 5 seconds after starting. If danger is imminent, it can make several sharp turns in succession to get rid of the enemy. Their fins can help swimming, just like penguins and turtles paddling.

The depth of 1000 meters is suitable for them to live in, but they can still be found at the depth of 13000 feet (4000 meters).

8.coffee fish

Coffin fish

Coffin fish has a soft body, a long tail and small spines all over. Coffin fish can grow to 10 cm long. This creature can be caught under the sea surface of the middle to east Indian Ocean1320-1760m.

7. Giant sea lice (giant isopod)

Giant deep-sea lice

English name: Giant Isopod (giant isopod)

Latin name: Bathynomus

Size: about 12- 16 inch (30.5-40.6 cm)

Habitat: all over the world

Habitat depth: over 2000 feet (6 10 m)

The giant deep-sea louse belongs to the crustacean isopod and is the largest member of the known isopod. People should be most familiar with its small isopod.

Although this big crustacean is not a vegetarian, it is not a fierce animal. It only cleans up animal carcasses on the bottom of the sea all its life.

Because of the lack of food in the deep ocean, deep-sea lice must adapt to the life of eating anything that falls from it. In addition to pies falling from the sky, they also eat small invertebrates living at the same depth as them.

The largest known giant deep-sea louse is over 40 cm in size and is one of the largest species in the crustacean family. This animal looks like a prehistoric creature, but when threatened, it behaves like a tidal bug, curling its body into a tight ball and making its back a hard armor to protect itself.

Compared with simple mouths like humans, their mouths are very complicated in structure, including many parts, which can cooperate with each other to pierce, tear and pull out internal organs. For them, the most suitable living temperature is 9 degrees Celsius. They lay the largest eggs of all known marine invertebrates.

The picture shows the newly hatched larva of the giant Arctic sea otter (Glyptonotus antarcticus), which lives in the islands around the Arctic Ocean and near the mainland, with the deepest habitat of about 790 meters. After hatching, the larvae will eat the unhatched eggs, while the female giant deep-sea lice in the Arctic Ocean generally die after laying eggs, and some can survive and reproduce.

6.king squid

Giant squid

English name: Giant Squid (giant squid)

Latin scientific name: Architeuthis dux

Size: 40-60ft (12.2-18.3m)

Habitat: all over the world

Habitat depth: as deep as 10000 feet (3048 meters).

This giant squid is one of the largest animals in the world and the largest invertebrate. It belongs to Cephalopods, Guniformes and giant squid families. Many Chinese articles also call it? King squid? . In fact, squid and squid are different. As far as ordinary squid and squid are concerned, their shapes are similar, but there are obvious differences: squid is long and narrow, which is a bit like the spear head of javelin, so it is also called squid.

Squid tentacles are not as long as squid tentacles, nor can they all shrink into the body. However, because the term "King Squid" has been used for a long time, it is also common in many formal articles, and it is probably a legal name.

Scientists don't know much about this animal, because people have never seen wild life so far. What we know comes from the bodies of giant squid washed up on the beach, and more from the bodies dragged by fishermen. They are carnivores, and according to the research on the food in their stomachs, they should not be picky about food and stuff almost everything into their stomachs. They have evolved big eyes, their eyesight is quite good, and there are a lot of creatures in the deep area where they live, so these giant squid follow the light with their big eyes, making it easy to hunt.

This is the first creature that scientists have seen. It is the larva of a giant squid and the protagonist of many ancient sea monster legends. Even during World War II, the crew of a sunken ship reported that their friends who were killed were eaten by these creatures at night. It is also reported that a giant squid ran into the sea and dragged the people on board into the sea. Although all these reports have not been officially confirmed, in many photos, they are portrayed as terrible and powerful predators.

5. Swallow eels (Swallow eels)

Swallow eel

Wide-pharynx fish

English name: Gulper Eel (swallowing eel) or Umbrellamouth Gulper (umbrella mouth devourer)

Latin name: European pepper snapper

Size: One can grow to 6 feet (1.8m), and the other can only grow to 30 inches (75cm).

Habitat: Global

Habitat depth: up to 5000-6000 feet (1, 524- 1, 829 meters).

This strange-shaped fish belongs to LEPIDOPTERA.

This typical deep-sea fish is one of the strangest creatures in the depths of the ocean. Its most striking feature is its big mouth. This eel has no movable upper jaw, but its huge lower jaw is loosely connected to its head, which never fits its mouth. It can easily swallow bigger animals with one mouth, so it can be obtained in the west? Umbrella devourer? The name of, and in Chinese is called? Wide-throated fish . The swallowed prey is put into the jaw bag like a fish swallowed by a pelican, so some people in the west call it an eel. This eel has no ribs, and its stomach is flexible, so it can expand and lay down its prey. But don't get me wrong, it mainly eats large animals. In fact, its staple food is unsalable small fish and shrimp, and it is still a minority when eating big meals.

These eels live in the deep seas of the world's oceans, with a habitat depth of 3,000-6,000 feet (9 14- 1829 meters), and it has also been reported that they inhabit 5,000-9,000 feet (1500-2,750 meters). Because the deep area is dark and vision is not important, their eyes are small. This eel also has a long whiplike tail, and those broad-throated fish that are dragged to the surface of the sea are often found to have their tails pricked several times.

Like many deep-sea fish, they also have a light-emitting device on the tip of their tail, which can emit red light. Some scientists think that they may often put their tails in front of their mouths as bait to lure their prey. Observations on them show that they like to swim in circles, perhaps because they want to chase their tail-chasing prey or wrap their long tails around their prey.

The juvenile broad-pharynx fish lives in the photosynthetic zone with a depth of 100 m to 200 m, and swims to the bottom of the sea after adulthood. There will be some changes in the body of adult male broad-throated fish, including the enlargement of olfactory organs and the degradation of teeth and jaws, while female wide-throated fish will not change.

4、? ? ? ?

? ? ? ? fish

? ? ? ? Fish is commonly known as oral fish, frog, frog, anglerfish and so on. This is a bony fish. ? ? ? Eyes? ? ? ? Family, a worldwide fish, distributed in the Atlantic Ocean, the Pacific Ocean and the Indian Ocean, with various species: maximum reach 1? 1.5 meters. There are only two kinds in our country. A little yellow? ? ? ? The other one is black? ? ? ? . The former has two more rows of mandibular teeth. White in the mouth, 8 ~ 1 1 arm fin; The latter has more than three rows of mandibular teeth, black and white circular stripes in the mouth and 6 ~ 7 arm fins. Yellow? ? ? ? Distributed in the Yellow Sea, Bohai Sea and the northern part of the East China Sea, black? ? ? ? More common in the East China Sea and South China Sea of China.

? ? ? ? Fish have two dorsal fins. The first dorsal fin is different from ordinary fish, and consists of 5-6 separate fins (6 are yellow? ? ? ? Five are black? ? ? ? )。

The first two pieces of silver are located on the back of the kiss. It has a leather nail at the top. Both the second dorsal fin and the arm fin are located at the tail. The pectoral fin is wide, lateral and round, and the base is arm-shaped, which helps the body slide. Short ventral fin, throat position. The caudal fin is round. The body is bare and scaleless, and there are cortical processes of different sizes above the head and on the side of the body.

? ? ? ? Fish is a medium-sized benthic fish, usually lurking on the bottom of the sea and not good at swimming.

This kind? ? ? ? The total length is only 10 cm. If you can't meet prey in the deep sea, try to swallow food bigger than yourself. Sharp teeth face inward, and once the prey is caught, it can't escape.

Johnson? ? ? ? Our stomachs can be as big as the one on the right, so that big prey can be swallowed.

Dense spine? ? ? ? Ceratophyllum, stinging? ? ? ? The female fish is much bigger than the male fish. On the left, the total length of female fish is 1- 1.2m, and the small male fish is only 8- 16cm. Males feed on females. The male fish bites the female fish and soon becomes a part of the female fish. The female fish like the ventral fin on the left is the parasitic male fish.

3. Deep sea arowana

Deep sea arowana

English name: deep-sea arowana or scaleless arowana.

Latin name: flagellate

Size: about 4-6 inches (10.2- 15.2 cm)

Habitat: tropical ocean

Habitat depth: up to 5000 feet (1.524 m).

The black giant mouthfish belongs to the order Megamouthfish. Although this fish is not big, it is a fierce predator.

What about the deep sea? ? ? ? Similarly, it has a big head, equipped with many long and sharp fangs, and what about the deep sea? ? ? ? Similarly, it also has a luminous bait, the only difference is that its luminous device is not on the back of the head, but on the jaw.

What about the deep sea? ? ? ? Similarly, it is constantly flashing, swinging back and forth to lure prey, and when the prey approaches, it holds on with sharp teeth. There are also two rows of luminous bodies on both sides of the giant mouth fish, which can send signals to other giant mouth fish during mating, and can also imitate the sparkling sea surface, thus misleading predatory fish in the depths below. The biggest difference between black giant mouth fish and other kinds of giant mouth fish is that they have a pair of luminous bodies under their eyes, which can serve as searchlights when searching for prey in the deep sea.

Visible light from the sky has been absorbed in the middle zone, and the deep zone has formed an extremely dark environment. In this environment, the eyes of the black giant mouth fish are specialized into a tube, and the photoreceptor cells are densely covered under the large lens.

Photosynthesis belt is full of sunshine and food is the most abundant. However, some crustaceans and copepods, which mainly feed on phytoplankton, escape from surface predators during the day, then migrate to the surface to find food at night when it is safer, and then return to deeper waters at dawn. Some deep-sea fish also migrate day and night to prey on copepods, and further, other large carnivorous fish follow closely, thus triggering large-scale animal migration activities. This behavior can increase the material exchange between the surface layer and the deep layer. Giant mouth fish is one of the fish that participate in this vertical migration day and night.

2. fangs

canine tooth

Horny golden-eyed snapper, English name: Fangtooth or Ogrefish, Latin name: Anoplogaster.

Size: about 6 inches (15.2 cm)

Habitat: tropical and temperate seas

Habitat depth: as deep as 16000 feet (4877 meters).

This fish whose English name is simple and easy to remember is called Loli in Chinese-a long-winded, angular tall golden-eyed snapper.

This kind of fish belongs to golden-eyed snapper and looks very threatening. Did they give it teeth? Fangs? The name and the terrible appearance make it get what it wants? Piranha? Such a horrible English name.

Fangs inhabit particularly deep places in the ocean. Although their most common habitat is 500-2000 meters, their horrible home is in the middle of an abyss as deep as 5000 meters, where the water pressure is terrible and the temperature is close to freezing point. There is a shortage of food here, so these fish eat everything they see. Most of their food may come from the upper ocean. Although this kind of fish is not afraid of cold, it is distributed in the depths of tropical and temperate oceans because more food falls from them. Adult fish with fangs look very different from young fish. The skull of young fish is long and light gray, with a big head and a big mouth, and the color ranges from dark brown to black. Young fish don't start to look like adults until they grow to 8 cm. Young fish eat crustaceans, and adult fish eat fish.

1, poisonous snake fish

Poisonous snake fish

Poisonous snake fish generally appears in the water layer 80- 1600 meters below the sea surface, which is one of the most disgusting fish in this deep sea. This fish has some black bodies and luminous organs in some parts of its body, including a long dorsal fin used as bait. Some poisonous snakes (and many other deep-sea fish) don't contain any pigment, so they look like? Transparent? Yes; They also have big eyes, in order to collect more light on the dark seabed; Luminous organs emit light through some chemical processes.
