Question 2: How do flying fish protect their paintings? What is a flying fish?
Question 3: What methods do fish have to protect themselves? 1. disguise.
Step two: escape
hide
Question 4: What skills do fish have to protect themselves? Rhinoceroses living in tropical waters of the Pacific Ocean and the Indian Ocean have a very powerful weapon-the tail thorn. It can bow left and right and stab each other with a knife on both sides of its tail. Swordfish's "long sword" can pierce the deck of a wooden boat, like a sword, and it is very easy to fight.
Some fish in the ocean have "advanced" defensive weapons. When they are hurt by the enemy, they can release the factory stream to hurt each other. For example, electric ray can emit 200 volts, electric catfish can emit 350 volts, and electric eel can emit 500 volts! Such a "high voltage" current really scared the opponent.
The octopus in the sea carries a black bag full of ink. When in danger, it shoots ink, fires "smoke bombs" and takes the opportunity to escape.
There is a catfish that can catch mice in the South China Sea. At night, the catfish swam to the shore shoal, put its tail out of the water and pretended to be a dead fish. When the foraging mouse finds out, it will bite the fish's tail. At this time, the catfish took the opportunity to drag the mouse into the water and have a full meal.
Flying fish uses a unique gliding to protect itself from the enemy's attack, but it will not fly around the sea without the threat of a strong enemy.
Question 5: How does the flounder protect itself? One side of the flounder's body is protective color, which is very similar to the color of seabed sand. It sank under the sand and exposed its eyes, so the enemy couldn't find it.
Question 6: How do river fish protect their common fish: protective color.
Flying fish: fly out of the water
Electric eel: discharge
Octopus: Change color and spit ink.
Swordfish: pierce with a sharp mouth
Clownfish: Rely on the thorn defense of anemones.
Flounder: Hidden in the sand at the bottom of the sea.
Question 7: How do small fish protect their flying fish? Fly out of the water.
Electric eel: discharge
Octopus: Change color and spit ink.
Swordfish: pierce with a sharp mouth
Clownfish: Rely on the thorn defense of anemones.
Flounder: Hidden in the sand at the bottom of the sea.
Question 8: Are flying fish protected? No, flying fish breed quickly, in large numbers and widely distributed.
Question 9: How do small animals protect their five-point protective colors? Animals adapt to their habitats and have colors suitable for the environment. It helps to avoid the enemy and hunt for food. There are many forms of protective colors: (1) The bodies of aquatic organisms such as jellyfish and sea squirts are almost transparent and can be cleverly hidden in water. (2) The white fur of polar bears is in harmony with the environment of ice and snow. Many fish have dark backs and light bellies, which are similar to the underwater background from above, but look like the sky from above. (3) Split colors are also protective colors, such as tigers, leopards, giraffes and zebras. They all have bright patterns, which can blur the outline with the cooperation of the surrounding dark and mottled environment. (4) Some flounder and lizards can change their body color with the change of background to keep harmony with the environment. The body color change of Anle lizard is controlled by endocrine, while the escaped pigment cells are controlled by nervous system. Protective color is gradually formed by the long-term co-evolution of predators and prey. The observation of mantis shows that when they are in a background close to their own body color, the possibility of being destroyed by natural enemies is three times lower than that in a background inconsistent with their own body color.
Jingjiese Some animals with foul-smelling, poisonous or inedible characteristics have bright colors or stripes, which play a "warning" role in the harm of enemies. It was formed during the long evolution of animals. For example, the larvae of poisonous moths often have bright colors or stripes, and birds that attack such larvae are often stabbed by their poisonous hairs. Therefore, this bright color or stripe naturally becomes the vigilance of birds. For example, a European toad can secrete a substance that annoys predators from skin glands, and its abdomen is bright red. Whenever it encounters an attack, it will turn its abdomen upwards, revealing a bright red belly. Because the enemy has a conditioned reflex to red and special stench, he has to give up the attack. There are poisonous golden ring snakes and silver ring snakes, with yellow and black garlands and black and white garlands respectively. This bright color makes many animals flinch. The yellow-black or black-and-white stripes of bees, and the spots and colors on the back of ladybugs are all warning colors. However, warning color has only relative significance in preventing enemy harm. Although ordinary birds dare not rashly attack the larvae of poisonous moths, the oral epithelium of rhododendrons has a special protective function, and they specialize in eating these larvae.
