Shark Week is back! Starting Sunday, July 31, at 9PM e/p, get ready for the most action-packed Shark Week ever.

Discovery kicks off its 24th annual Shark Week with the all-new special Great White Invasion at 9 p.m. It’s a fascinating examination of why great white sharks are swimming closer to shore in Southern California, Australia, and South Africa, and who’s really at risk — us or them.

Chief Shark Officer Andy Samberg hosts the greatest week on television, including seven brand-new shark shows.

Shark Week was invented to help the average person have a greater respect for sharks as more than killing machines.
