The black mamba is one of the world's most venomous snakes, native to parts of sub-Saharan Africa. It can grow up to 14 feet long and is known for its speed, capable of moving at 12 miles per hour. Its name comes from the black coloration inside its mouth, which it displays when threatened. This snake primarily inhabits forests, savannas, and rocky hills. The black mamba is a diurnal predator, feeding mainly on small mammals and birds. Its venom contains neurotoxins that can cause death within hours if untreated, making it a significant concern for humans in its range.
