1. Brahminy blind snake (Ramphotyphlops braminus)
Probably the most widespread and the first among the most common non-poisonous snake species in the world is the brahminy blind snake, named after Brahmin caste of priests in Hinduism. This snake has many common names, mostly known under names lowerpot snake, common blind snake, island blind snake, etc., spread throughout almost every continent and island. Maybe the most interesting fact about these snakes, apart from that they are completely blind, is that they are the only snake species that are unisexual, meaning there are no male brahminy blind snakes. That is why they have easily spread throughout the world – only one specimen is enough to create a new population. These are tiny snakes (being only around 7 inches long), and mostly resemble earthworms, both in looks and behavior, since they spend most of the time burrowing underground.
