All Todays Snake's Description
Fossils of these mostly legless animals have been found in almost every landmasses except Antarctica. Snakes had no known functional legs, so it remains unknown to how snakes had moved. It was once thought that snakes were a kind of fish that lived underwater, but scientists and paleotologists have found no evidence to support this theory nor find any signs of gills for breathing water or could find any features that indicates they could swim. Snakes were very likely warm-blooded very much like today's mammals and birds, so to survive the cold, they were probably covered in fur, much like mammals (and snakes were probably mammals), or were covered in thick feathers, much like birds (and snakes were probably birds). However, it is possible that in the tropical and humid habitats, snakes didn't need fur nor feathers, so they had thick scales much like crocodilians, so snakes could have been bizarre legless crocodiles. Snakes ranged from the size of a medium-sized earthworm to about 30 feet depending on a species. Some species of snakes even had large fangs, possibly used to hunt larger animals to cut down the windpipes of larger animals such as dylanuses, humans, cattle, pigs, peccaries, tapirs, sheep, goats, and among other animals smaller than hippopotamuses, making snakes such as rattlesnakes among the deadliest predators of the Holocene. Some even had bizarre ribcages just bellow their skulls, indicating that they sported skin flaps to attract mates or to scare off rivals. Their teeth indicated that they were carnivores in most species, but some species such as the coral snakes, vipers, and gopher snakes were found with no teeth or lost teeth and some herbivorous tooth were found to fit these tooth holes, suggesting that these snakes were plant eaters that fed on fruit and leaves. Most species of snakes likely lived to be around 9 years old, but few species of giant snakes such as the anaconda and the giant python likely lived to be 27-31 years old.
Introduction to real life North America
Ever since they were brought to real life North America through universe travel, they flourish alongside real snakes and all other species that are living in North America. Unlike their ancestors, they are no longer aggressive towards any sapient species/beings nor pets or real dylanus species, so they are now allowed to live in cities.
