What level of protection is the white-tailed dolphin?

Question 1: What level of national protection is the baiji dolphin? The white-finned dolphin is commonly known as white-finned dolphin, white-finned dolphin, and river horse. Belongs to the class Mammalia, order Cetaceans, and family Baijidae. Its distribution is limited to the middle and lower reaches of the Yangtze River, especially in the Yangtze River sections in Hunan, Hubei, Anhui, and Jiangsu below Shashi in Hubei Province. Baiji dolphin is a rare aquatic mammal unique to my country. It is a valuable material for studying the evolution of cetaceans and biological evolution. It has a developed brain and is a smart and intelligent animal. It has special functions such as "echolocation" and sonar. With a streamlined body shape, abundant subcutaneous fat, and agile swimming, these structures have important scientific value in bionics. The body of the white-finned dolphin is spindle-shaped. The snout is extremely long and narrow, and the upper and lower jaws are almost equal in length and slightly upturned. The body length is 6 times the snout length. The body color is blue-gray on the back and white on the abdomen. There are semi-circular white wide stripes on both sides of the neck, behind the ear holes and above the flippers. There are two half-moon-shaped white wide stripes on the tail side above the penis. Baiji dolphins like to move in the mainstream area of ????the center of the river far away from the shore, and are a sparsely human dolphin species. They have the habit of swarming in their movements. They often move in groups in the middle of the river, and occasionally move into lakes, tributaries and the confluence of the Yangtze River main stream. Baiji dolphins breathe with their lungs and come out of the water to breathe every one or two minutes. When ventilating, the head always comes out of the water first, sometimes sprays of water will spray out, and there will be a sound when breathing out of the water. When the weather is sultry and heavy rain is approaching, it frequently rises and falls out of the water, and the masses call it "White Fin Baijiang". Baiji dolphins are carnivorous animals with poor vision. They rely on the ultrasonic signals they emit to detect food and devour it in a surprise attack. Their feeding habits are mainly fish, and they often forage in shoals, forks and confluences of tributaries. Its food intake is very large, and its general food intake can account for 10% to 12% of its body weight. Baiji dolphins reach sexual maturity at the age of 6 for females and 4 for males. The reproductive and mating period is from April to June, and the gestation period is about 9 months, giving birth in the river in January or February of the following year. Female dolphins only give birth to one litter per year, one calf per litter, and occasionally twins. Newly born baby dolphins nurse their mothers' milk until they grow up and move around with the group. After the completion of the Gezhouba Dam and the Three Gorges Dam on the Yangtze River, the ecological environment of the Yangtze River has undergone drastic changes. The development of the shipping industry, river regulation, the increase in motorized vessels, water pollution, siltation of rivers and lakes, the use of harmful fishing gear and harmful fishing methods, etc., seriously threaten the continuation of the white-tip dolphin race. According to actual statistics, there are now less than 100 Yangtze white-tip dolphins, far less than the national treasure giant panda. In order to prevent the baiji dolphin from becoming extinct in nature, the country has listed it as a first-level protected animal, and designated the Tian'ezhou Ancient Road of the Yangtze River and the Tongling River section of Anhui as nature reserves to protect and increase baiji dolphin resources and save endangered species.

Question 2: What kind of animal is the baiji dolphin, a first-level protected animal in my country? Breastfeeding

Question 3: What level of protected animals are whales? Hello! Except for the white-tip dolphin and the Chinese white-sided dolphin, which are listed as national first-level protected animals, all other whale species in my country are listed as second-level protected animals.

Question 4: Elephants are nationally protected animals at several levels. Asian elephants (Latin name: Elephas maximus), also known as Indian elephants, elephants, and Asian elephants, belong to the family Elephantidae of the order Proboscidea.

The Asian elephant is the largest terrestrial animal in existence. The tusks, which are more than 1 meter long, are the incisors that protrude outside the mouth of the male elephant's upper jaw and are also powerful defensive weapons. The elephant's eyes are small and its ears are large, and the ears are set back to cover both sides of the neck. The limbs are thick and strong, with 5 toes on the forelimbs and 4 toes on the hind limbs. The tail is short and thin, the skin is thick and wrinkled, and the whole body is covered with sparse short hair. The top of the head is the highest point, with a body length of 5-6 meters, a height of 2.7 meters, and a weight of 4-5 tons.

There are very few wild elephants now, and there are many domesticated and draft elephants in some Southeast Asian countries. my country's wild elephants are only distributed in the border areas adjacent to Myanmar and Laos in southern Yunnan Province. Their numbers are very rare and they have been hunted repeatedly, causing serious damage. It is a national first-level protected animal.

Behind the eyes, the external auditory canal has disappeared. So the answer is: Baiji is a warm-blooded mammal; the characteristics of Baiji are: constant body temperature, viviparous breastfeeding, breathing with lungs, a diaphragm in the body cavity, a long and narrow snout, and equal lengths of the upper and lower jaws, like those of a bird.
