Well,today I am going to show some articles about snakes which I found it interesting.Snake is an elongated reptile of the suborder Serpents. Like all reptiles, snakes are exothermic and covered in scales.
All snakes are carnivorous and can be distinguished from legless lizards by their lack of eyelids, hind limbs and external ears. Snakes are found on every continent except Antarctica and Artic regions. Their size ranges from a tiny 10 cm long thread snake to enormously huge snakes such as pythons and anacondas of up to 7.6 m (25 ft) in length. In order to accommodate snakes' narrow bodies, their paired organs (such as kidneys) appear one in front of the other instead of side by side like most animals.
Most species are non-venomous and those that have venom use it primarily to kill and subdue prey rather than for self-defense. Some possess venom potent enough to cause painful injury or death in humans. Snakes are thought to have evolved from either burrowing or aquatic lizards during the Cretaceous period (c 150 Ma). The diversity of modern snakes appeared during the Paleocene period (c 66 to 56 Ma).
A literary word for snake is serpent, a Middle English word which comes from Old French, and ultimately from serpernt, "to creep", also ερπω in Greek. The serpent is also a symbol of medicine due to its association with Asclepius,the Greek god of medicine. Fifteen families are currently recognized comprising 456 genera and over 2,900 species.
Well this is the article I am showing you now is to tell you something that happened to me some time back when a snake was actually slithering on my neck. It was DISGUSTING!!!! At the Singapore Zoo "night safari", my family and I were watching the trainer showing us how to hold the snake. As usual, he would pick some audience to try it out. I was hoping it wasn't me but unfortunately...it was.I picked up all my courage and move up to the stage and hold the snake.It was scaly and heavy too and I finally knew how a snake feels like,Sssssss... ...
