The main differences between salamanders and salamanders are different subject classifications, different morphological characteristics, and different living habits. The details are as follows:

1. Different subject classifications

1. Salamander

The salamander, also known as the four-legged fish, belongs to the order Uruna, Salamanderidae, and the genus Salamander.

2. Salamander

Salamfish generally refers to the giant salamander, which belongs to the order Cryptobranchidae and the genus Giant Salamander.

2. Different morphological characteristics

1. Salamander

The body of the salamander is plump and cylindrical, much like a reptile lizard, dragging A long, flattened tail. The skin is moist, moist, and sticky, and the body color is unusually bright—either with obvious markings or comb-like protrusions. Salamanders have short limbs and unwebbed feet. Adults have eyelids and can move them, but larvae have no eyelids.

2. Salmonfish

The body of the giant salamander is large and flat, with a large, flat and broad head. The head length is slightly longer than the head width. There are thick longitudinal skin folds and several round warts on the sides of the body. The limbs are thick and short, the hind limbs are slightly longer, and the fingers and toes are flat; when the front and rear limbs are close to each other, the distance between the tips of the fingers and toes is about 6 costal grooves.

The body surface is smooth and moist, and small warts are arranged in pairs on the dorsal and ventral surfaces of the head; the warts around the orbits are more neatly arranged and more concentrated, and the thick longitudinal skin folds on the side of the body are obvious, upper and lower The warts are larger; the skin in other parts is smoother. The body color varies greatly during life, and is generally brown. The variant colors include dark black, reddish brown, brown, light brown, loess, gray brown and light brown.

3. Different living habits

1. Salamander

Animals of the genus Salamander live in puddles, ponds or rice fields in hilly swamps and near them. From October to March of the following year, they usually hibernate in gaps in the soil or under rocks near water bodies. From March to September, they are mostly active in puddles or rice fields on the mountainside with abundant water and grass. Benthic, crawling slowly and rarely swimming. They mostly feed on earthworms, molluscs, insect larvae, etc. at the bottom of the water.

2. Salamander

Adult salamanders usually inhabit rock caves and stone caves in deep pools of streams and rivers below an altitude of 1,000 meters. They are more common in caves above and below the mouth of the beach. , often lie in caves during the day and seldom go out for activities. In summer and autumn, they also have the habit of going ashore to feed or bask in the sun during the day. Giant salamanders usually come out at night and return in the morning, often living in a cave. Predation is mainly carried out at night. They often wait among the rocks at the mouth of the beach. When they find prey animals passing by, they suddenly open their mouths to prey. Giant salamanders are suitable for inhabiting water with a water temperature of 3 to 23°C.

The Chinese giant salamander has slightly different food sources in different waters. They eat a lot and mainly prey on fish, crustaceans, amphibians and small arthropods in the water. In addition, in the stomach of the giant salamander Small amounts of plant components are also found. The giant salamander lives in its habitat in the Yangtze River Basin, and there are fish such as white turtle, wide-mouthed light lipped fish, and horsemouth fish, which provide the giant salamander with a wide range of prey.
