Will you ever get a date? When will your skin clear up? Adolescence holds many mysteries; likewise the new live-action series “House of Anubis,” set at a coed English boarding school that is simply groaning with secrets. (Nickelodeon, 7 and 7:30 p.m.)

In the jungle, the mighty jungle, the lion sleeps tonight — but his pride is on the prowl! The special “Night of the Hunt” (below) uses super-sensitive cameras to capture otherworldly images of lady lions making their nocturnal rounds. (National Geographic,

7 and 10 p.m.)
