Jameson’s Green Mamba

Jameson’s mamba (Dendroaspis jamesoni) in Mbanjong.

The snake lives in trees.
It is a front-fanged elapidae snake.

The Jamesons Mamba, and other mambas, are a big hit for biomedicine;

they produce one of the most used tools to understand how the human nervous system works and their toxin is a template for a heart failure medicine in clinical trials.

Most snake venoms kills by either of two mechanism, respiratory failure and loss of blood pressure. Mambas are unique, they employ the both strategies at the same time.
Mambas have highly toxic venom which consists mostly of neurotoxins. The bite can be fatal to humans
without access to proper first aid and subsequent antivenom treatment, as it shuts down the lungs and heart.

Toxins work like key finding a lock. Once a toxin (key) finds its targets (lock) then it specifically fits there and prevents the lock from open / closure. So it cannot work anymore. The key disables the lock.
