Snake
Serpentes
Snakes are legless squamate reptiles in the suborder Serpentes, a group with more than 3,900 living species. They range from tiny blind snakes that live in soil to large pythons, boas, racers, vipers and sea snakes. Shared traits include a long scaled body, no external ear openings, no movable eyelids, a forked tongue used for scenting and flexible skull bones that help many species swallow large prey. Some snakes are venomous, but most are not dangerous to people when left alone.
Human relationships with snakes vary widely. Corn snakes, kingsnakes, ball pythons and some boas are common captive reptiles, while venomous snakes and giant constrictors belong with licensed, experienced keepers or professional institutions. Care begins with correct identification, escape-proof housing, species-specific heat and humidity, suitable hiding places and appropriate prey; many common pet snakes thrive on pre-killed rodents, but others need fish, amphibians, eggs or invertebrates. Rescues often handle surrendered impulse purchases, and wildlife teams focus on safe relocation, public education and protecting habitat that supports native snake populations.
