What are marine swimming creatures
In 1912 and 1916, O. Abel of Austria, in his works on vertebrates and cephalopods respectively, for the first time classified aquatic organisms belonging to different categories, with different body shapes, but with a certain tendency in action as swimming organisms. After the 1930s, the morphological function of marine swimming organismsWho is the swimming champion of the ocean
The fastest fish swims in more than 30000 kinds Ocean swimming  1912 and 1916of fish. In terms of swimming speed, the champion is sailfish. Sailfish gallop like arrows in the vast sea area, traveling at a speed of 120 kilometers per hour, three or four times faster than ships. If the sea route from Tianjin to Shanghai is more than 1300 kilometers, sailfish can swim the whole journey in more than 10 hoursWho is the real swimming champion in the ocean
The champion swimmer in the ocean is the sperm whale. Sperm whales are very suitable for diving because they are top heavy and light. They can hold their breath in the water for 1.5 hours and dive to the deep sea of 2200 meters. The champion of diving in the ocean should be the sperm whaleDistribution and migration of marine swimming organisms
The land margin swimming organisms are mainly Ocean swimming  1912 and 1916distributed in the water layer more than 100 meters. Some deep-water species, such as lepto nychotes weddelli, can dive into the deep-water layer of 600 meters. Many species of marine swimming organisms have directional periodic movement, which is called migration. By migratOcean swimming  1912 and 1916ionAdaptation of marine swimming organisms to swimming life
Marine swimming organisms not only have developed motor organs, balance organs, muscle system, nervous system, vision and various morphological structures that adapt to different habitats, but also have some special adaptive functions and habits. For example, most species living in the open sea, such as mackerel, tuna, dolphin, etc., have typical streamlined body shapeWhat are the characteristics of marine swimming organisms
In 1912 and 1916, O. Abel of Austria, in his works on vertebrates and cephalopods respectively, for the first time classified aquatic organisms belonging to different categories, with different body shapes, but with a certain tendency in action as swimming organisms. After the 1930s, the morphological function of marine swimming organismsWhat kind of animal is a swimmer in the ocean
Dolphins are excellent swimmers in the ocean, and their maximum swimming speed can reach 40 ~ 50 km / h. Dolphins' bodies are streamlined, which can greatly reduce resistance. However, when swimming, the surface of the body will still rub against the current. When the resistance increases, ordinary ships overcome the flow resistance with the help of propellers and other propellersIntroduction to marine swimming organisms
Marine swimming organisms are those that can overcome the resistance of water flow and swim freely in the water layer. They all have developed motor organs and are an ecological group of marine organisms. In 1891, the German scholar E. h. hackle first used the word "nekton". The word nekton comes from Greek s。What animals are the swimming creatures in the sea
The swimming creatures in the sea refer to those animals with developed motor organs and strong swimming ability. Including fish, mammals (such as whales, dolphins and seals), reptiles (such as sea snakes and turtles), software animals (such as squid and octopus) and some large shrimps (such as shrimp and lobster), their swimming abilityWhat are the main characteristics and reproductive characteristics of marine swimming organisms
