Wild Sharks, a film by Sigurd Tesche, follows Professor Samuel Gruber who has been researching sharks for more than fifty years. He founded the Bimini Biological Field Station, called the Sharklab, on Bimini Island in the Bahamas.

Wild Sharks continues in the mangroves of Bimini Island, the islands most valuable asset, as we learn about and follow mating nurse sharks and other ocean wildlife, including eagle rays and remoras.

During the night, Sam Gruber's team of biologists has captured a young tiger shark, a perfect candidate for their scientific research.

Sam Gruber's team of biologists capture, tag and release a juvenile tiger shark. Then they track it electronically into the mangroves, an ideal location for their research.

Gruber's team of researchers work day and night. In this episode they record a shark's vital statistics while it's in a state of tonic immobility. Before releasing it, they take a DNA sample. Enjoy!

At times, Doc Gruber's research requires the team to dive right into shark-infested waters! Their line of work certainly isn't for the faint of heart! Enjoy.

Nathalie and Jim get up close and personal with tiger and lemon sharks, trying to get the best footage while taking care not to disturb or excite the dangerous animals.

The team's divers conclude their filming and come back to the surface unharmed. We learn more about current developments in the prevention of shark attacks.

In this episode, Doc Gruber and a colleague are testing a shark repellent. If effective, it could help save the lives of divers, swimmers and surfers all over the world.

Here's some more stunning underwater footage. This time it's hammerhead sharks and stingrays, a wahoo and some striped eels, all filmed near the Cocos Island in the Caribbean. Take a look!

Samuel Gruber's team films white-tipped sharks and barracuda feeding at night off Cocos Island. Enjoy!

This December over 190 nations will gather in Paris to discuss a new global agreement on climate change. The talks are called 'COP21' which stands for the 21st annual Conference of the Parties, but what does all that mean and why is any of it important?
