For this week, we’re highlighting the lives of cheetahs through exceptional photography. From curious cheetahs on the lookout in Tanzania to a dog playing with a cheetah at the zoo, this picture selection explores the fastest land animals in the world.

Bariadi, Shinyanga, Tanzania.

“The cheetah (Acinonyx jubatus) is a large feline (family Felidae, subfamily Felinae) inhabiting most of Africa and parts of Iran. It is the only extant member of the genus Acinonyx. The cheetah can run faster than any other land animal — as fast as 112 to 120 km/h (70 to 75 mph) in short bursts covering distances up to 500 m, and has the ability to accelerate from 0 to 100 km/h in three seconds.” – Lea Duckitt
