Creatures in the deep sea, what creatures are in the deep sea

Deep-sea organisms can be divided into three categories: planktonic, swimming, and benthic according to their lifestyles.

1. Plankton.

It is composed of some species such as bacteria, protozoa, coelenterates, crustaceans, hairy-jawed animals, etc., and the number of species and organisms is smaller. The number of organisms usually decreases significantly with increasing water depth. Deep-sea zooplankton are mostly omnivorous or carnivorous.

Many marine zooplankton have a diurnal vertical migration habit, which usually occurs by rising to the upper or surface layer to feed at night, and sinking to the depths of the ocean during the day, ranging from tens of meters to hundreds of meters. Zooplankton feed on phytoplankton at night, and after sinking to the deep layer during the day, their own respiratory metabolism, excretion, and predation by animals with higher trophic levels all lead to an important way for the transport of organic carbon from the upper layer to the deep layer.

2. Swimming creatures.

Swimming creatures in the deep sea are mainly fish, followed by squid, octopus and shrimp.

The origin of the Soviet scholars Andreyetsev and Lasy deep-sea fish divided it into two categories: primary (native) deep-sea fish and secondary (secondary) deep-sea fish. Primary deep-sea fish refer to those ancient deep-sea fish and oceanic deep-sea fish, this group of fish has been adapted to deep-sea life since ancient times, belongs to the family and suborder, and is composed of a wide range of species (such as horned shark whale suborder, lantern fish, cyst-throated fish).

3. Benthic organisms.

Deep-sea benthic organisms refer to the organisms that live on the bottom of the deep sea and cannot swim in the water for a long time, mainly including microbenthic organisms with an individual size of 2 40 m, small benthic organisms with an individual size of 42 1000 m and large benthic organisms with an individual size of more than 1000 m, the deep benthic biomass decreases with the water depth, there are more benthic species at the water depth of 2000 3000 m, and there are still benthic organisms in the abyss above 10,000 meters. Isopods, telopods, gills and sea cucumbers, etc.

Creatures below 100,000 meters in the deep sea are:

1. Long-snouted silver shark.

The body length is 60 200 cm, and the female is larger than the male. The body is stretched and the sides are flat. There are more than 20 species in 2 genera distributed in the Pacific and Atlantic coasts, and 4 species in 2 genera in China, distributed in the East China Sea and the South China Sea.

2. Vampire squid.

It is a luminescent creature covered in glowing organs that allow them to switch themselves on and off at will. When it turns off the light-emitting device, it is completely invisible in the dark environment it is in.

3. Giant deep-sea lice.

It belongs to the crustacean class of isopods and is the largest known member of the isopods, and its small isopod siblings, the tide worm, should be the most familiar one.

This large crustacean, while not a vegetarian, is not a ferocious animal either. They spend their lives cleaning up animal carcasses from the bottom of the sea.

4. Deep-sea Arowana.

It has a large head with a large number of long, pointed fangs. Similar to the Deep Sea CK, it also has a light emitter lure, except that it does not grow on the back of the head, but on the lower jaws.

5. Viper fish.

Usually found in water formations between 80 and 1,600 meters below the surface, the venomous snakefish is one of the most odious fish in this deep ocean. Some of these fish are black all over their bodies, and some parts of their bodies have luminous agitators, including long dorsal fins, which are used as bait.
