snake
snake Any of
c.2700 species of legless, elongated
reptiles forming the suborder Serpentes of the order Squamata (which also includes
lizards). There are 11 families. They range in length from
c.10cm (4in) to more than 9m (30ft). There are terrestrial, arboreal (tree-dwelling), semi-aquatic, and aquatic species; one group is entirely marine; many are poisonous. They have no external ear openings, eardrums or middle ears; sound vibrations are detected through the ground. Their eyelids are immovable and their eyes covered by a transparent protective cover. The long, forked, protractile tongue is used to detect odours. Their bodies are covered with scales. Poisonous snakes have hollow or grooved fangs, through which they inject venom into their prey.
