What is in the deep sea?

Question 1: What's terrible about Bermuda Triangle? What horrible creatures are there in the deep sea? The secret of Bermuda Triangle has long been solved. Because there is a natural tunnel under the ground, which crosses the American continent and goes straight to the Atlantic Ocean. In tidal flood season, due to the directional flow of a large number of water bodies, a huge undercurrent or vortex is formed underwater. This is why the ship will be sucked into the bottom of the sea after passing. This huge vortex also caused the disorder of geomagnetic field, so the compass also failed.

Question 2: What magical creatures are there in the deep sea?

1. sperm whale sperm whale is a typical deep-sea diver. They can dive thousands of feet underwater and prey on deep-sea squid and fish. Sperm whales spend more than 90% of their lives diving into the abyss. Scientists believe that in terms of biodiversity, deep-sea areas are not inferior to tropical rainforests. Scientific research has found that there are different kinds of life on the seabed thousands of meters deep. They have completely adapted to this extreme environment. 2. The grotesque coelacanth is one of the oldest fishes in the world and is usually regarded as a living fossil. Coelacanth was once thought to have been extinct as early as 65 million years ago. However, a fisherman once caught a coelacanth in the waters near the coast of South Africa in 1938. In 1950s, another man caught a second coelacanth on the east coast of Africa. Since then, people have found the living coelacanth many times and recorded it by taking pictures. The sea where coelacanth is found is mainly concentrated in the Indian Ocean, from the southwest coast of Africa to Indonesia. The coelacanth lives in an environment about 700 meters deep. 3. Japanese giant spider crab Japanese giant spider crab lives at the bottom of the sea about 400 meters deep. It is the largest crab in the world. Crab legs can be up to 4 meters long. Because giant spider crabs are edible, catching giant spider crabs has become an important branch of aquaculture. In order to protect this species, giant spider crabs are forbidden to fish during spawning. During the breeding season, giant spider crabs swim to shallow waters, so they are easier to be caught. The most famous thing about black spider crab is that it can swallow others much older than itself.

Question 3: Is there light in the deep sea? There are natural luminous objects in the deep sea, but they can't be used for lighting. The sun's light refracts a little, but after all, it is a deep ingot, and the deeper it is, the less light there is. Those photos were taken by light;

Question 4: What's in the deep sea? It's time to open your brain.

But one thing is certain, there is water.

Question 5: What animals are there in the deep sea? The deep sea is characterized by dullness, high water pressure, high salinity and low water temperature. According to human cognition, there are no plants in the deep sea at present. Deep-sea animals are mostly detritus, only a few carnivores, which decrease with the increase of seawater depth. There are mainly echinoderms: sea cucumber, sea urchin, sea lily and starfish; Crustacea: shrimp, crab, deep-sea fish; The ecological characteristics of deep-sea fish are: large mouth, sharp teeth, highly developed eyes or tactile organs and soft body. In the water depth above 1000 meters, there are often marine life with luminous organs or tissues, mostly microorganisms, plankton, invertebrates and a small amount of fish.

Question 6: Is there sunshine in the deep sea? If the fish knows, let it cook slowly at the bottom of the sea!

Question 7: What plants are dominant in the deep sea? Seaweed is the main body of marine plants. Scientists divide algae into planktonic algae and benthic algae according to their living habits. Benthic algae are bright and beautiful in color, including green, brown and red. Scientists divide algae into three categories according to their colors: green algae, brown algae and red algae. The body of green algae is grass green. There are about 6,000 species of green algae, 90% of which are produced in fresh water, and only 10% live on rocks in intertidal or subtidal zones. Green algae have single cells and colonies; There are filiform and flaky. The most common marine unicellular green algae is Platymonas, which is rich in protein and is a good bait for small and medium-sized marine animals. The most common multicellular green algae are Ulva and reef membrane (called sea spinach or sea cabbage by fishermen along the coast of China), which are popular marine economic vegetables. There is also Enteromorpha, which can be used to make Enteromorpha cakes. It tastes delicious. In addition, there are feather algae, bracken, sea pine, umbrella algae and so on. The algae body of brown algae is brown, multicellular, filamentous, flaky or leaflike, some are saccular, tubular, cylindrical or dendritic, and generally have disc-shaped or branched fixers or rhizomes. There are stems and leaves on the rhizome, commonly known as pseudostems and Ye Jia. Large species of brown algae, such as kelp, can grow to 7 meters to 8 meters long; Giant seaweed can grow to 300 meters long and is known as "undersea forest". Most of them grow on rocks in the low tide zone or below the low tide line. The algae body of red algae is purple or purplish red, mostly multicellular, filamentous, flaky and branched. There are various shapes, such as circle, ellipse and strip. Most red algae like to live in the deep sea, growing near the low tide line and 30 ~ 60 meters below the low tide line, and a few species can grow on the seabed of 200 meters. There are more than 2,500 kinds of red algae, among which the most common ones are Porphyra, Gelidium, Chaetoceros, Myxomycetes, Aphrodite, Myxomycetes, Spiraea, Scolopendra, Hedysarum, Polysiphonophora and Parthenocissus. Porphyra purplish red, flaky, fresh or dried. Dried laver is the best-selling non-staple food in the market. Marine lichen, which is the life of algae.

Question 8: What fish are there in the deep sea? In the past, the research on fish in Taiwan Province Province mainly focused on the classification and biological investigation of coral reef fish and its coastal economic fish. On the other hand, the collection and research of deep-sea fish are relatively lacking, mainly because there are no boats and nets for collecting deep-sea fish, and only a few are found on bottom-towed fishing boats that can be towed to 600-700 meters. The Institute of Zoology, Chinese Academy of Sciences, under the guidance of MUSORSTOM, France, purchased 10,000-meter-long steel cables and installed them on the "Haiyang No.1" research ship, which enables bottom trawls (beam trawls and single trawls) to work in the depth of several thousand meters on the seabed. In addition, we also designed and made the Intermediate Net (IKMT) by ourselves, so that the study of deep-sea creatures is no longer limited to the collection of benthic fish. In five voyages in the past year, more than 65,438+050 species of deep-sea fish were caught, including: Cicadellidae, Megadonta, Schibranchiata, Chondrichthys, Deep-sea cK, ... In this exhibition, we selected various exotic deep-sea fish belonging to 18 families, in addition to introducing the above four groups individually.

Family name: Nitidae.
