A rattlesnake.

Snakes form the reptile class Serpentis. All are carnivorous, swallowing their prey whole, and most are generalist feeders, with several well-known exceptions, such as cobras.


All snakes are limbless. They have long bodies that can coil around surfaces and grip. They have a huge variety of sizes, from just 10cm long to at least 7 metres in length, and just a few centimetres to almost a foot in width.


All snakes feed on other animals.
