Saving Sawfish - Trailer

2m 17s / TV-G

Strange and prehistoric-looking, Smalltooth Sawfish were once coveted by anglers as popular trophy fish. But habitat loss and overfishing have greatly reduced the animals’ range and landed them on the endangered species list in 2003.

Galápagos: Windows into the Future - Trailer

3m 9s / TV-G

The unique oceanic conditions of the Galápagos Islands serve as a perfect natural laboratory to study how climate change may impact corals in the future. A coproduction with the Khaled bin Sultan Living Oceans Foundation.

Living Fossils - Trailer

2m 29s / TV-PG

In the deep, dark waters off the coast of Roatan, Honduras, strange flowerlike animals flourish. These sea lilies and feather stars, known as Crinoids, have been around in various forms since before the age of dinosaurs.

Biggest Fish in the Sea - Trailer

2m 36s / TV-G

Each summer, the world’s largest known aggregation of whale sharks occurs just off the coast of Cancun, Mexico. Hundreds of these gentle giants come to the area to feed on plankton, giving experts the opportunity to learn more about the largest fish in the sea.

Reefs of Rangiroa

2m 51s

Scientists with the Global Reef Expedition are on a six-year mission to study remote coral reefs around the world. Organized by the Khaled bin Sultan Living Oceans Foundation, the expedition kicked off in 2011, with plans to conduct research in the Atlantic, Pacific and Indian Oceans. A coproduction with the Khaled bin Sultan Living Oceans Foundation.

Creatures of the Deep - Trailer

2m 2s

In the cold, deep waters of the Gulf of Mexico, little-known animals spend their entire lives in near darkness, far removed from our human world. Until now, little research has been conducted on these creatures of the deep, keeping much of their lives a mystery.

Coral Hybrids - Trailer

2m 33s

Once a common sight in the Caribbean and Florida, Elkhorn and Staghorn corals are now listed as threatened on the U.S. Endangered Species list. But while these corals have declined in recent years, their hybrid appears to be increasing in parts of the region.

Coastal Carnivores - Trailer

1m 53s

Scientists studying the coastal Everglades have made some perplexing discoveries. Bull sharks are living upstream where alligators should thrive, and gators are swimming out to the ocean to feed. A coproduction with Symbio Studios.

Grouper Moon - Trailer

1m 40s

During the winter full moons, Nassau Grouper gather in large numbers to spawn. Most of the known spawning sites have been fished out, but the Cayman Islands are home to the last great reproductive population of this endangered species.

Mysterious Microbes - Trailer

2m 40s

On coral reefs, microorganisms are copious creatures. Throughout Florida, scientists painstakingly work to identify key players within this microbial community and directly link a devastating coral disease to a human pathogen.

Tracking Tigers - Trailer

1m 44s

Tiger sharks are the ultimate apex predator. Scientists use satellite tags and DNA forensic tools to better understand the migrations of this magnificent species and to investigate the impacts of the world shark fin trade.

After the Spill - Trailer

3m 13s

The catastrophic oil spill in the Gulf of Mexico in April 2010 may no longer make headline news, but the story is far from over. Oceanographers continue to study the long-term effects this disaster might have on marine ecosystems.

Prescription Oceans - Trailer

2m 36s

The oceans are part of America’s newest medical frontier. In Florida, scientists are studying a variety of marine invertebrates which may hold the key to unlocking the secrets of our own biology.

Reef Revival - Trailer

1m 56s

In the emerging science of coral reef restoration, marine biologists and resource managers are discovering naturally occurring mechanisms that promote coral growth and restore ecological balance in these gardens of the sea.

Alien Invaders - Trailer

2m 3s

In the waters of the western Atlantic and Caribbean, a voracious alien predator has taken hold. Native to the Indo-Pacific, the invasive lionfish is a major threat to biodiversity and the health of already stressed coral reef ecosystems.

Sinking the Vandenberg - Trailer

1m 46s

Off Key West, in the Florida Keys National Marine Sanctuary, lies the world's second largest intentionally sunk shipwreck, the USNS General Hoyt S. Vandenberg. This artificial reef is now attracting fish, fishermen and divers.

Seagrasses and Mangroves - Trailer

2m 11s

They are an ancient species of flowering plants that grow submerged in all of the world’s oceans. Seagrasses link offshore coral reefs with coastal mangrove forests. Today, these prairies of the sea, along with mangroves, are declining globally. Scientists fear the diminishing vegetation could result in an ecosystem collapse from the bottom of the food chain all the way to the top.

No Fish Left Uncounted - Trailer

2m 37s

How do you count two fish, three fish or even a school of fish? In Dry Tortugas National Park, located 70 miles from Key West, Florida, a group of scientists have joined forces to conduct a massive fish census.
