蛇是爬行纲动物演化史中最迟出现的类群，最早的蛇化石出土于距今七千多万年的中生代白搜趣网垩纪地层内。蛇和蜥蜴的亲缘关系密切，许多学者经过研究发现：较原始的细盲蛇科的蛇中，体鳞呈覆瓦状排列，腹鳞小而分化不明显；上颌骨、腭骨、翼骨等颅骨密接，方骨短，限制了蛇嘴的极度张开；下颌保留着冠状骨；有乌喙骨和腰带骨。
巨蜥科的分叉之舌，以及美洲鬣蜥科（Iguanidae）的椎骨结构和血红蛋白经蛋白酶水解所产生的肽类指纹图等，均与蛇相似。更有甚者的是蜥蜴目中不但具有四肢退化而呈蛇形的蛇蜥科、蚓蜥科的种类。
并且还能在不同类型的蜥蜴之间看到其肢体长度比例上逐渐缩短直至萎缩消失的过程。这些实例都无可争辩地证实了蛇是渊源于蜥蜴，并循着身体延长和丧失四肢演化而从蜥蜴主干上所分化出的一个分支。
有关蛇的英文介绍
后天（周五19号）早上我们在课堂上要进行英文演说，一时没有找到有关蛇的英文详细解说，拜托帮我找些有关蛇的习性，饮食等的英文说明。稍微多点~THANKSThe Anaconda is also foot per foot a much bigger snake than the Python, being both heavier and wider in girth. This is probably because the anaconda, a water snake, does not have to be concerned about getting its body up a tree like the python does. For these reasons the museum reports the anaconda as the largest snake, though on the average some Pythons grow longer.
Do large snakes like the python and the anaconda eat people? Occasionally such attacks are recorded in the wild. In 1972 a python in Burma ate an eight-year-old boy. In 1927 there was the story about a jeweler called Maung Chit Chine. He hid under a tree during a rain storm and afterward his friends could only find his hat and shoes. When they killed a nearby gouged Python, they found the rest of Chines' body, swallowed feet first (though this seems opposite to normal snake behavior) and whole, inside the snake.
Strangely enough, many big snakes attack humans not in the jungle, but in suburbia. Pythons are often kept as pets, but can turn deadly without warning. In 1993 in Colorado, a 15-year-old boy weighing 95 pounds was attacked by the fam搜趣网ily's python. The snake was only of medium size bwww.souquanme.comeing 11 feet long and weighing 53 pounds, yet was able to kill the boy, though it made no attempt to eat him.
Cartoonist Gary Larson, of The Far Side, also had a close call with a Burmese python he had raised from a baby. According to Larson he realized he was "living with a gigantic predator with a very small brain" one day when it tried to do him in.
Large snakes, though beautiful and interesting, can be dangerous. And they don't have to live in the jungle to kill.

蛇的特点的描写（//www.souquanme.com英文）
要3句话，描写外形、生活习性都可以无前肢带，身体表面覆盖有鳞。部分有毒，但大多数无毒。
它们栖息于墓洞中，洞口可见稀稠成粒的粪便，这样我们就知道洞中有没有蛇了。蛇有冬眠的习性，到了冬天盘踞的洞中睡觉，一睡就是几个月，不吃不喝，一动不动地保持体力。风和日立的天气，偶尔也会出来晒太阳，有时也会进食。待到春暖花开，蛇就醒了，开始外出觅食，而且脱掉原来的外衣。蜕皮时，蛇的新旧皮之间会分泌出一种液体，这种液体有助于蛇的蜕皮。从蛇蜕的外衣直径和长度可测出蛇重量甚至说出蛇的名称。蛇蜕皮后不久，//www.souquanme.com活动量增大，觅食量增加，体况逐渐恢复。随着气温逐渐上升，到4月下旬至5月上中旬进入发情期。
眼镜王蛇又称山万蛇、过山风波、大扁颈蛇、大眼镜蛇、大扁头风、扁颈蛇、大膨颈、吹风蛇、过山标等。同样具有眼镜蛇的大多数特点，只是体形更大更长，颈部扩展时较窄而长，且无眼镜蛇的特有斑纹。但它性情更凶猛，反应也极其敏捷，头颈转动灵活，排毒量大，是世界上最危险的蛇类。在我国主要分布于华南和西南地区。它的主要食物就是与之相近的同类──其他蛇类，所以在眼镜王蛇的领地，很难见到其他种类的蛇，它们要么逃之夭夭，要么成为眼镜王蛇的腹中之物。眼镜王蛇的毒液，由位于眼睛后方的唾腺分泌而成。当眼镜王蛇咬住猎物时，毒液会通过它的约8-10公分的毒牙注入伤口中。除了加蓬蝰蛇外，眼镜王蛇所分泌的毒液比其他毒蛇都要多，它一次分泌的毒液足以在3个小时内毒死一头亚洲象。
