Yes, venomous, but rarely encounters humans as it is usually in trees (very unusually on the ground) and are shy. This hooding behavior is known in the Black Mamba but never recorded before in the Green Mamba.
Beautiful but probably dangerous hmmmm

Are you sure it's a hood as the neck appears to be stretched only when it lifts it's body above the ground and there is no frontal evidence of any green mamba spreading a hood
They are absolutely gorgeous, and so fast
