The largest amphibian in the world is:

The world's largest amphibian - the giant salamander In the mountains and streams of the middle and lower reaches of the Yangtze River, the Yellow River and the Pearl River in China, the world's largest amphibian lives - the giant salamander. Its appearance suddenly looks a bit like a child, and its cry resembles a child's cry, so it is generally called a baby fish. It is a precious animal endemic to our country.

As early as 2000 years ago, many books mentioned that "salamanders have four legs, like a turtle and walk fast, have the body of a fish, and like feet, and sound like a child's cry". It can be seen that the giant salamander has long been known to people. The salamander is not a fish, it belongs to the amphibians.

The body is flat and strong, the head is broad and rounded, the mouth is large, and the eyes are extremely small. The limbs are short, especially the forelimbs resemble a pair of small arms of a child, the tail is flattened, and the back is brown with cloud spots of varying sizes. A man with a body length of 65 kilograms was caught in Hunan.

Baby fish generally live in mountain streams and rivers with turbulent water currents at an altitude of 100-2000 meters, cool water quality, and many stone crevices and caves. During the day, they often lurk in caves with flowing water, one hole and one tail. They hunt mainly at night, often waiting among the rocks at the mouth of the beach, and when they find food passing by, they open their mouths and swallow it.

The salamander mainly feeds on frogs, fish, snakes, shrimp and aquatic insects, and it is very resistant to hunger, and will not starve to death if it is kept in cool water for two or three years without eating. Females lay eggs in caves in rocks, where they lay more than 300 eggs at a time, and after laying their eggs, they play freely, leaving the task of raising the second generation to the males. The male salamander bends his body into a semi-encircled shape and encloses the eggs to avoid being swept away by running water or predators, and does not leave until the young salamanders hatch.

The giant salamander also has the longest lifespan among amphibians, living up to 130 years in captivity. The meat of the giant salamander is white and tender, and it is delicious, and it is listed as a treasure. In the past, due to the large number of people who did not know how to protect wild animals, they were ruthlessly overfished, resulting in serious damage to the resources of many areas, and some areas were on the verge of extinction.

Now, China has stipulated that the salamander must be protected.

The giant salamander is the largest amphibian and one of the few species that has survived hundreds of millions of years of evolution.

Commonly known as baby fish.

Feeding habits of giant salamanders

Giant salamanders have poor eyesight, mainly through smell and touch to perceive external information, they can also sense the vibration in the water through the warts on the **, and then catch fish, shrimp and insects in the water. The Chinese giant salamander occupies the top position of the food chain in its ecosystem and is an important link in the biological chain.

Chinese giant salamanders in different waters, the food is also slightly different, they eat a large amount, mainly prey on fish, crustaceans, amphibians and small arthropods in the water, in addition to the stomach of the giant salamander is also found in a small amount of plant components. Living in the habitat of the giant salamander in the Yangtze River Basin, there are white turtles, broad-mouthed glossy lipfish, horsemouth fish and other fish, which provide a wide range of predation objects for giant salamanders.
