Snakes are extended, legless, predatory reptiles of the suborder Serpentes that can be recognized from legless reptiles by their absence of eyelids and outer ears. Like all squamates, snakes are ectothermic, amniote vertebrates canvassed in covering scales. Numerous types of snakes have skulls with a few a larger number of joints than their reptile predecessors, empowering them to swallow prey significantly bigger than their heads with their exceedingly versatile jaws. To suit their limited bodies, snakes' combined organs, (for example, kidneys) seem one before the other rather than one next to the other, and most have just a single useful lung. A few animal groups hold a pelvic support with a couple of minimal hooks on either side of the cloaca. Living snakes are found on each landmass with the exception of Antarctica, and on most littler land masses; exemptions incorporate some vast islands, for example, Ireland, Iceland, Greenland, the Hawaiian archipelago, and the islands of New Zealand, and numerous little islands of the Atlantic and focal Pacific seas. Also, ocean snakes are across the board all through the Indian and Pacific Oceans. More than 20 families are presently perceived, including around 500 genera and around 3,400 species.They extend in size from the small, 10.4 cm (4.1 in)- long string snake[6] to the reticulated python of 6.95 meters (22.8 ft) long
