Are snakes mammals? A detailed explanation of the animal classification of snakes

Snakes are not mammals. Snakes belong to the reptiles, they do not suckle after birth, and they are a fairly common type of cold-blooded animal. In evolutionary terms, mammals are more complex and advanced.

1. Are snakes mammals?

Snakes are not mammals. Snakes belong to the reptiles. Reptiles are cold-blooded animals with dry, gland-free skin, they excrete uric acid, and so on; these are the characteristics of reptiles that are relatively primitive in evolutionary terms. Mammals, by contrast, are more complex, higher organisms in evolutionary terms: warm-blooded, viviparous, suckling their young, with a developed central nervous system, skin with glands, excreting urea, and so on; these are the ways in which mammals are more evolutionarily advanced than reptiles.

2. How long do snakes live?

Different snakes have different lifespans, mainly related to the species or the living conditions. In general, small snakes live about 2 to 5 years, medium-sized snakes about 5 to 12 years, and large snakes 10 to 20 years; pythons can live to 30 to 40 years, or even longer. However, in the wild, because their habitat is not very stable, food is sometimes scarce, and they are seriously threatened by natural enemies and disease, snakes do not live as long as they do under captive-bred conditions, and many scientists have proved this through experiments as well.
