No, Agkistrodon halys and black mamba are two kinds of snakes. The death of Africa means that the black mamba belongs to the Agkistrodon family, which belongs to the Cobra family. Cerastes cerates (scientific name: Cerastes cerates) is a reptile belonging to the genus Agkistrodon. Toxic, mainly distributed in North Africa and the Middle East, their characteristics are obvious, and their eyes have a pair of erect prickly horny scales, so they are easy to identify. However, horned nettles without horny scales were also found. No other species have been found under this species. The black mamba snake (scientific name: Dendroaspis polylepis), also known as "Black Tree Cobra", is the second largest terrestrial snake and the largest mamba snake, with an average length of 2 meters and the longest length of 4.3 meters, second only to the king cobra in the poisonous snake world. The black mamba snake is the largest poisonous snake in Africa and is known as the death of Africa. Like other mambas, the black mambas not only live in trees, but also hunt on the ground, mainly feeding on small mammals such as mice, lizards and birds. The black mamba snake is also the fastest moving snake in the world, with a speed of19.5 km/h. It can stand up half the length of its body, but its purpose is to climb trees, not to attack humans.
