These snakes are fast—they can slither up to 12 miles per hour.

They're long—they've been known to reach up to 14 feet.

And they're venomous—extremely venomous. Some have even been known to call the black mamba the most dangerous snake in the world.

For one conservationist in South Africa, catching black mambas, or any reptile for that matter, is one of his favorite past times.

"It's what I live for!" said Nick Evans in an email with National Geographic.

Evans runs the KwaZulu Natal Amphibian and Reptile Conservation organization in Durban, South Africa. Their mission focuses on education and dispelling common misconceptions about snakes. Evans also frequently removes them from properties in Durban.
