Why animals don t get disoriented and what animals don t have a sense of direction

Two new studies reveal how animals use their own inherent "compass" to identify directions. Researchers have found that migrating sea turtles rely on regional magnetic fields to guide them through the North Atlantic. Sea turtles avoid entering dangerously cold waters by orienting themselves along a circulating flow system known as the North Atlantic Gyre.

Sea turtle pups from eastern Florida begin their long migration as soon as they enter the sea. They swim towards the North Atlantic gyre that surrounds the sargassum sea area and spend several years swimming along this circulation.

Scientists studied how the turtle cubs reacted to different magnetic fields by placing them in a large tank surrounded by computer-controlled coils. Each turtle is equipped with an electronic tracker that records the turtle's location. Sea turtles can respond to certain changes in the magnetic field by changing the direction in which they swim.

In another study of Zambian subterranean mole rats, researchers in the Czech Republic and Germany found that some nerve cells in a brain structure called the epithalamus are part of the animal's biological "compass". These groups of cells respond selectively to different magnetic field directions. Moles use this magnetosensory information to synthesize a mental topographic map of their surroundings, while other animals use different sensory information to achieve the same topographic map.

The animal with the least sense of direction is the elk.

In addition, elk is a mammal of the artiodactyl deer family, because its head and face are like horses, horns are similar to deer, neck and neck like camels, and tails like donkeys, and are called four dislikes, which belong to one of the world's rare animals.

Elk is a large herbivore, its body length is 170-217 cm, the weight is 120-180 kg, but adult male elk can weigh up to 250 kg, in addition, the neck and back of the elk are stout, the limbs are strong and powerful, there is a skin between the toes, and there are well-developed hanging hooves.

Habits

Elk are gregarious and good swimmers, feeding mainly on grasses, mosses and other young grasses and leaves. The feed types of artificial breeding are composed of three parts: "fine grains" include wheat bran, barley, corn, and soybean cake; Soybean straw has a high degree of fibrosis and is a "coarse grain".

The "fine grains" and "coarse grains" are crushed separately, mixed with water and stirred and fermented according to a certain proportion, and at the same time, fresh and delicious carrots, wheat green and other "fruits and vegetables" are used to supplement vitamins.

The elk has no sense of direction, and it is a brain teaser because the homonym for elk is lost. Elk is a mammal of the order Artiodactyl, the deer family, and the elk genus, also known as the "four dislikes". Elk is a rare animal in the world and belongs to the cervid family.

Because its head and face are like horses, its horns are like deer, its hooves are like oxen, and its tail is like a donkey, it is named Four Likes.

In nature, the animals with the most sense of direction are: turtles, pigeons, camels, etc.

Sea turtles: During the spawning period, sea turtles have to go to a safe place dozens of kilometers away to lay eggs, and swim back the same way after the eggs are laid; Pigeon: The pigeon can use the earth's magnetic field to navigate, so it has the ability to return thousands of miles. Camel:

Camels can maintain their sense of direction. He relied on his natural sense of direction so that he could not get lost in the desert.

Elk has wide hooves and skin membranes between the toes, and it prefers warm and humid environments, so the ideal habitat for elk is in the plain wetlands of the Yangtze River Delta, as well as swampy areas, in addition, elk like to move in groups.
