National Geographic’s popular summer series “Sharkfest!” is returning in July. The network is teaming up with Nat Geo WILD to offer five full weeks of shark programming, with 17 original premieres slated for the event. The eighth annual “Sharkfest” will begin on July 12th, on National Geographic, followed by two weeks of content on Nat Geo WILD, starting on August 2nd.

“For the past eight years, Nat Geo and Nat Geo WILD have been THE destination for viewers to get up close and personal with one of the world’s most awe-inspiring creatures, and this summer we’re eating up the competition AGAIN with an unprecedented line-up of action-packed shark shows,” said Geoff Daniels, executive vice president of global unscripted entertainment at National Geographic. “Over five full weeks, our viewers will get the ultimate home field advantage to witness the ocean’s super stars in their prime, so pull up your beach chairs and get ready for some SHARKFEST!”

This season’s starting lineup for Sharkfest on Nat Geo includes the following: (as described by National Geographic)

World’s Biggest Tiger Shark?: Marine biologist Kori Garza and Emmy Award-winning underwater cinematographer Andy Casagrande journey to French Polynesia to track Kamakai, one of the largest tiger sharks on record. Their search takes them to a remote lagoon where, instead of Kamakai, they find what appears to be a discovery for shark science. Capturing the behavior on film for the first time, Garza and Casagrande witness a population of juvenile tiger sharks exhibiting cooperative hunting tactics.

When Sharks Attack: For families on beaches across the world, a split second is all it takes to turn a dream vacation into a nightmare. Sudden shark attacks frequently occur, and the motive behind the bite often puzzles locals and scientists alike. When Sharks Attack investigates these incidences to shed light on why and where shark encounters take place with the hope that if we understand the behavior, we might be able to limit the number of attacks.

Sharks vs. Dolphins: Blood Battle: There’s a war being waged beneath the waves: sharks versus dolphins. These marine animals shared the ocean for millennia, but scientists have only just begun to understand the complex relationship between sharks and dolphins. Sharks vs. Dolphins: Blood Battle follows a team of experts as they travel to the epicenter of this savage struggle — Shark Bay, Australia — to unlock the secrets of shark and dolphin combat. New research allows for a fresh understanding of sharks, and cutting-edge technology provides a window into this seldom-seen conflict below the water’s surface.

Sharkcano: World-renowned shark scientist Dr. Michael Heithaus is on a mission to reveal the mysterious connection between sharks and volcanoes. Throughout the world, sharks seem to be attracted to the hotspots, a puzzle that seems straight out of sci-fi and is baffling scientists. Dr. Heithaus crisscrosses the globe and risks life and limb to uncover the shocking, real-life link between two fearsome forces of nature.

Secrets of the Bull Shark: Many experts consider bull sharks to be the most dangerous species of shark, yet we actually know very little about these top predators. Secrets of the Bull Shark unravels the mystery of these giants: how they migrate and how they hunt. Marine biologist Dr. Ryan Daly and a team of scientists utilize cutting-edge technology to reveal the movements and behavior of the bull sharks with the hope of better understanding why they venture farther into our backyards. With unprecedented detail, the scientists track their development from tiny hunters into intelligent, ferocious predators.

Most Wanted Sharks: Of the millions of sharks in our oceans, a select few are so fascinating, they’ve become worldwide celebrities with legions of fans and followers. In Most Wanted Sharks, marine biologist and shark-suit inventor Jeremiah Sullivan dives into the stories of the most sensational shark stars of all time. Come face-to-face with a shark so large, it’s been known to eat fellow great whites for dinner. And get up close to one that can jump 100 feet out of the water.

50 Shades of Sharks: Sharks have long been considered calculating and vicious apex predators of the ocean, but new research allows for a glimpse of some of their most intimate and seldom-seen behaviors. 50 Shades of Sharks reveals facets of sharks that are rarely chronicled; they’re fragile, delicate, ingenious, collaborative and even clumsy. This full immersion into their private lives shows them hunting, resting, cleaning and reproducing; these revelations might forever change the way we look at sharks.

Raging Bull Shark: Bull sharks are entering the ring and going head to head with the more fearsome, storied great white and tiger sharks to prove they’re the new champion of the chomp. As climates warm the world’s waters, the notoriously aggressive bull shark’s territory is spreading, leading to an uptick in attacks. Following a team of experts, Raging Bull Shark chronicles why the deceptively unremarkable species just might become the world’s most dangerous shark.

Sharks of the Bermuda Triangle: The Bermuda Triangle has more than 500,000 square miles of rumored mysteries, including missing airplanes, sunken ships, malfunctioning compasses and even legends of Atlantis. In reality, its greatest wonder may be something far more incredible: sharks. For years, marine biologist Dr. Austin Gallagher has been investigating sharks in the area; he’s been on a mission to find the holy grail of shark research: the secret breeding grounds of tiger sharks. Tracking an elusive tiger shark named Mabel, he attempts to uncover Mother Nature’s most mysterious hotspot.

Shark vs. Whale: A routine drone survey turns deadly when Ryan Johnson, a marine biologist based in South Africa, films a humpback whale being attacked and strategically drowned by a great white shark. The never-before-seen behavior causes a complete perspective shift on a creature Johnson has spent his life studying. To make sense of the event, he follows humpback whales on their migration, mapping places that may make them vulnerable, and takes a new look at great white sharks to discover how and why they become whale killers.

What the Shark?: Exploring the shallow waters of sandy beaches and venturing into 8,000-foot abysses, What the Shark? takes a look at a side of sharks rarely seen and dives deep into the environments where extreme adaptation is critical to survival. In this dark void, where inky darkness could hinder a predator from finding its prey and pressure levels might blow flesh to pieces, the atmosphere is a threat to a shark’s survival. To endure these hostile waters, this ghostly cast of living monsters must have its act together to defy the convention of life below the surface.

Shark vs. Surfer: As the number of shark attacks worldwide rises, surfers are taking the brunt of the bite. Shark vs. Surfer visits shark-infested surf spots around the world to relive some of the most harrowing shark and surfer stories through unbelievable, caught-on-camera encounters and interviews with the victims. With insight from marine biologists Ryan Johnson and Dr. Steven Kajuira, the special aims to answer once and for all: Are we really in danger?
