Snake is a long-bodied, legless, normal title of reptiles. They type a crowded suborder of the vertebrate reptiles (Reptilia) class, which is included within the scaly reptiles (Squamata). are divided into 5 sections. These divisions additionally include numerous households. About 3000 species of snakes are identified on the planetOnly a few of them are poisonousThey’re cold-blooded (variable temperature) carnivores that reside in scorching areasThere isn’t any exterior ear gap and membrane. The tip of their tongue is forked and will be prolonged and pulled via a slit within the decrease jaw. The higher and decrease eyelids mixed to type a clear lens like a watch glass.

Their scales are shaped from the thickening of the sexy layer overlaying their our bodiesOn this means, the lack of water within the physique by evaporation is prevented. The form and coloration of the scales overlaying their our bodies play an essential position in classification. Since they don’t have glands, their pores and skin is at all times dry. They alter their pores and skin every now and then because it prevents progress. The enamel are used to carry the meals and are tilted backwards. Venomous snakes even have lengthy grooved venom fangs on the anterior jaw. In these, the salivary glands have become venom glands. Their hearts are three-eyed. Combined blood is discovered within the ventricle, which is partially separated by a half membrane.
