Salamander
"Salamfish" is an amphibian The largest one among them, the total length can reach 1 meter or more, and the heaviest one can weigh over 100 kilograms. The shape is somewhat similar to a lizard, but fatter and flatter in comparison. Scientists study: When the giant salamander is young, it uses its gills to breathe, and when it grows up, it uses its lungs to breathe. Giant salamander rests in streams in mountainous areas and survives in caves with clear water, low sand content, fast currents and backflow water. The giant salamander has a flat, blunt head, a large mouth, undeveloped eyes and no eyelids. The front part of the body is flat, and gradually turns to side flatness towards the tail. There are obvious skin folds on both sides of the body. The hands and feet are short and flat, with fingers and toes four in front and five in back, and slightly webbed. The tail is round, with fins on the left and right sides of the tail. The body color of giant salamanders can change with different environments, but they are generally gray-brown. The body surface is smooth and scaleless, but has various patterns and is filled with mucus. The face on the belly of the body is light. English: Chinese giant salamander. Looking at the frogfish, it turns out that its real name is the Oriental salamander, not the real giant salamander. Oriental salamanders can be kept in fish tanks, and they need to be exposed to sunlight occasionally, but not too much. How to feed? Axolotls can be kept in a large glass fish tank to facilitate observation of their movements. Spread some clean gravel at the bottom of the tank, pour 30 cm deep pool or well water, and add some goldfish (certain introduction) algae and other aquatic plants to create an ecological environment similar to the capture site. Sand and gravel can absorb dirt; aquatic plants can perform photosynthesis, reduce the oxygen content in the water, and provide newts with the ability to lay eggs.
Giant salamanders are violent and carnivorous, feeding on aquatic insects, fish, crabs, shrimps, frogs, snakes, turtles, rats, birds, etc. The method of catching food is "wait for the rabbit". Giant salamanders generally live in the rock crevices of mountain streams, and the caves are located below the water surface. It stays quietly among the rocks at the mouth of the beach at night. Once it finds its prey behind, it launches a sudden attack. Because the teeth in its mouth are sharp and dense, it is difficult to escape after the prey enters its mouth. Its teeth are unable to chew, but it opens its mouth to swallow the food whole, and then slowly digests it in its stomach. Giant salamander has a strong resistance to hunger. It will not starve to death even if it is kept in cool water for two or three years without eating. It can also overeat at the same time, and a single meal can reduce one-fifth of body weight. When food is scarce, species will fight each other and even eat eggs to satisfy their hunger.
