The zoo is home to species including an African grey parrot, a vervet monkey, giant lizards known as Nile monitors, a desert tortoise, a horned viper snake and a Nubian spitting cobra.

The Saharan horned viper and the sidewinding adder of the Namib desert — which are closely related — have belly scales with uniform pits and no spikes.

Indeed, the best footage here is captured at night, from the slinkings of the bizarre horned viper to the evasive tactics of the lesser jerboa, a tiny rodent with kangaroo-like hind legs.

Matilda’s horned viper was discovered in the African nation of Tanzania about two years ago and was introduced last month as the world’s newest known snake species.

The Wildlife Conservation Society reports the discovery of a striking snake, the Matilda’s horned viper, in eastern Tanzania.
