Big Cat Week is finally here!

Nat Geo WILD's fourth annual tribute to the great cats starts Friday, Nov. 29 with a slew of features that hope to shed light on the growing threats many of these predators face. One of the highlights of the week will be the film "Game of Lions," featuring famed National Geographic Explorers-In-Residence Dereck and Beverly Joubert. The film delves into the dwindling number of lions left on the planet and their fight to stay alive, both among themselves and encroaching humanity.

Take a look at some stunning photos from Beverly Joubert below, and tune in to see "Game of Lions" on Dec. 1 at 10 p.m. EST.

Check back on Sunday for an interview with the Jouberts about the making of the film -- for a full lineup, head on over to the Big Cat Week website.

An adolescent male is investigating a lion cub of a lioness from his pride. He follows the cub around and sometimes the investigating becomes rough, especially with other adolescents around. The mother is not around to protect the cub and so it is very vulnerable. This image was taken in the Masai Mara in Kenya.

Three sub adult males, around 2 1/2 years old, stand together. They are very close to the stage of getting ousted from their pride, meaning they will be nomadic for a few years until they are old enough to challenge a territorial male. This is a tough time for adolescent males as they are incredibley vulnerable and only 1 in 7 normally survive.
