Snakes are elongated1, legless, carnivorous reptiles2 that can be distinguished3 from legless lizards5 by their lack of eyelids6 and external ears. Many species of snakes have skulls7 with several more joints8 than their lizard4 ancestors, enabling them to swallow prey9 much larger than their heads with their highly mobile jaws10. To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional11 lung.
 
Living snakes are found on every continent except Antarctica, and on most smaller land masses; exceptions include some large islands, such as Ireland, Iceland, Greenland, the Hawaiian archipelago, and the islands of New Zealand, and many small islands of the Atlantic and central Pacific oceans. Additionally, sea snakes are widespread throughout the Indian and Pacific Oceans. More than 20 families are currently recognized. They range in size from the tiny, 10.4 cm (4.1 in)-long thread snake to the reticulated python of 6.95 meters (22.8 ft) in length. The fossil species Titanoboa cerrejonensis was 12.8 meters (42 ft) long. Snakes are thought to have evolved from either burrowing12 or aquatic13 lizards, perhaps during the Jurassic period.
 
Venom14 毒液
Most species are nonvenomous and those that have venom use it primarily to kill and subdue15 prey rather than for self-defense. Some possess venom potent16 enough to cause painful injury or death to humans. The colloquial17 term "poisonous snake" is generally an incorrect label for snakes. A poison is inhaled18 or ingested, whereas venom produced by snakes is injected into its victim via fangs19. It is worthwhile noting that certain birds, mammals, and other snakes (such as kingsnakes) that prey on venomous snakes have developed resistance and even immunity20 to certain venoms21. Nonvenomous snakes either swallow prey alive or kill by constriction22.
 
Feeding and diet 飲食
All snakes are strictly23 carnivorous, eating small animals including lizards, frogs, other snakes, small mammals, birds, eggs, fish, snails24 or insects. Because snakes cannot bite or tear their food to pieces, they must swallow prey whole. The body size of a snake has a major influence on its eating habits. Smaller snakes eat smaller prey. Juvenile25 pythons might start out feeding on lizards or mice and graduate to small deer or antelope26 as an adult, for example. After eating, snakes become dormant27 while the process of digestion28 takes place.
