On the coast, two worlds collide. Coasts are the most dynamic and challenging habitats in the ocean - that brings great rewards but also great danger. The extraordinary animals that live here must find ingenious ways to cope with two very different worlds. This episode is a rollercoaster ride of heart-stopping action and epic drama, peopled with characters from the beautiful to the bizarre. We meet fish that live on dry land and puffins that must travel 60 miles or more for a single meal, and witness a life-and-death struggle in a technicolour rock pool. In a secluded cove in the Galapagos, sea lions feast on 60kg tuna. It should be impossible - tuna are usually far too fast for sea lions to catch. But here the sea lions club together to herd their prey inshore. Once trapped in the shallows, these huge fish are easy pickings. As the tide recedes in Brazil, lightfoot crabs leap from rock to rock, desperately avoiding the water - their lives depend on it. Moray eels launch themselves from rock pools, jaw gaping. Then octopuses, too. Both crawl across dry rock to set their ambush. Elsewhere, the ever-changing tides create rock pools. But these temporary worlds are a battleground. Predatory starfish turn a magical garden into the stuff of nightmares.

Highly decorated special agent Hector Berellez, who was assigned to lead the DEA's investigation of Camarena's murder, peels back the layers of myth and propaganda to reveal the bone-chilling truth about a conspiracy that stretches from the killing fields of Mexico to the halls of power in Washington, D.C.

Moral psychology isn't always an easy thing to study. Experiments that actually puts people in what feels like a real scenario may get realistic results, but researchers must always balance the benefits of what we could learn with the safety and well-being of the people they study. Often what we learn from moral psychology experiments doesn't make humans look good.
We are imperfect creatures. But the more we learn about why and how we make the moral choices that we do, the better we'll be able to tackle difficult questions in the future.

David the filmmaker is 40 years old, but he still doesn't feel like a man - not a real man anyway. When his wife becomes pregnant with a boy, David's manhood insecurities deepen.

My Own Man is an intimate, humorous, and emotional account of one man's search for what it means to be a man and a father in the 21st century.

Life goes to extraordinary lengths to survive this immense realm. A 30 tonne whale shark gorges on a school of fish and the unique overhead heli-gimbal camera reveals common dolphins rocketing at more than 30km an hour. Descending into the abyss, deep sea octopus fly with wings and vampire squid use bioluminescence to create an extraordinary colour display. The first ever time-lapse footage taken from 2,000m down captures eels, crabs and giant isopods eating a carcass, completely consuming it within three hours.
