扩展资料
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 jewewww.souquanme.comler 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 family's python. The snake was only of medium size being 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 closeoiYAWkeD 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.
