"Bull Shark Dinner Bell" premieres at 8 PM ET/PT on Discovery

Shark attack survivor and advocate Paul De Gelder teams up with apex predator specialist Rosie Moore in Jupiter, Florida to investigate what triggers giant bull sharks to confront humans, testing human behavior in the ocean, extreme weather events and prey preferences to determine what factors ring the loudest dinner bell.

Off the coast of New Zealand lies a hidden shark battleground, where three distinct groups of great whites organize into competing "houses" and may be competing with one another to gain control of a major seal feeding ground. Marine biologist Dr. Tristan Guttridge and underwater cinematographer Kina Scollay venture into the middle of the action on an epic expedition, using brand new builds and massive blood bombs to document this new competitive behavior. As they investigate, they uncover the possibility that these clans of great whites recognize kin and return season after season to their ancestral territories, raising the theory that these predators aren't solitary hunters, but rival dynasties at war.

Bloodlines. Alliances. Rivalries. This isn't fantasy…it's happening beneath the waves 麗

"Biggest Mako on Earth" premieres at 10 PM ET/PT on Discovery

For decades, rumors have swirled about massive,15 to 20-foot mako sharks patrolling the deep waters off Southern California. Long dismissed as fishermen's tales, new footage, along with a recently published photo capturing a mako that appears to push 15 feet, is now forcing scientists to rethink everything they know about these oceanic apex predators. Marine biologist Tristan Guttridge, alongside conservationist Kendyl Berna and shark tagger Keith Poe, leads an investigation to determine whether the world's biggest mako is real, and hunting in the coastal waters of Santa Catalina.
