While we focus on snakes of Thailand and Southeast Asia, you may be looking for the answer to the question “Which Black Snake Is It?” and you’re in the USA, Australia, or Europe. We list some of those too. There are some black snakes that are always black, and there are some black snakes that are highly melanistic – with an excess of melanin – and they can also be black. Do keep that in mind as you look at the black snakes below. We feature some COMMON black snakes below.
