Behavior[change | change source]
Because mambas and cobras are in the same family, they share some similarities. Like the cobra, a mamba might display a hood when threatened. However, a mamba's hood is more narrow and is longer. A mamba usually opens its mouth when threatened, so they lean forward unlike the cobra which usually stands erect.
Venom[change | change source]
All mambas are very venomous. Their venom is mostly comprised of neurotoxins, which attack the nervous system. The venom can also contain cardiotoxins (which damage the heart muscle) and fasciculins (which cause muscle twitches).
All mamba species have similar venom, but the black mamba has the most toxic venom and is more aggressive.
