Dendroaspis is a genus of highly venomous snakes commonly known as mambas. They are native to sub-Saharan Africa and are recognized for their long, slender bodies and agile movements. Mambas are typically green or black, with the black mamba being one of the most well-known species due to its potent venom and speed. These snakes are primarily arboreal, meaning they often live in trees, although they can also be found on the ground. Mambas are diurnal, hunting during the day for small mammals and birds. Their venom contains neurotoxins that can cause rapid paralysis, making them one of the most dangerous snakes in the world.
