Lice don’t just thrive in the biomes of body hair and fur, they can also live in a place that seems like it should be bug-free: the oceans.

The bowhead whale lives its entire life - which amazingly can span over 200 years - in the frigid Arctic waters near the North Pole. The bowhead whale is unlike most other whales as it doesn’t seasonally migrate in search of warmer...

Oceanographer Kate Stafford lowers us into the sonically rich depths of the Arctic Ocean, where ice groans, whales sing to communicate over vast distances -- and climate change and human noise threaten to alter the environment in ways we...

We still don't know a lot about the deep sea, but thanks to the help of three dead alligators, we know more about the diets of some of the creatures that live there.

The best evidence we have suggests that, while Caviomorpha originated in South America, they came from ancestors in Africa, over 40 million years ago. So how did they get there?

Mammals are a warm-blooded family capable of living in every environment on Earth, from icy tundras to vast oceans. Characterized by fur or hair, live births, and nurturing their young, mammals range from land giants like elephants—led...

At a site known as Cerro Ballena or Whale Hill, there are more than 40 skeletons of marine mammals -- a graveyard of ocean life dating back 6.5 million to 9 million years ago, in the Late Miocene Epoch. But the identity of the killer...

Sunning themselves on rocks or waddling awkwardly across the beach, it's easy to think of sea lions more as sea house cats. But don't be fooled by their beachside behavior. Under the waves, sea lions are incredible endurance hunters,...

Humans can’t go too far above or below sea level unaided, but there are some complex forms of life that CAN survive at super high elevations or in the deepest parts of the ocean.

The marine reptiles Ichthyosaurs arose after The Great Dying, which wiped out at least 90 percent of life in the oceans, changing the seas forever and triggering a new evolutionary arms race between predator and prey.

The age-old mystery of why otherwise healthy dolphins, whales and porpoises get stranded along coasts worldwide deepens: After a collaboration between NASA scientists and marine biologists, new research suggests...

The video explores the impact of plastic pollution on marine life and the environment, featuring interviews with marine biologists and researchers who study the effects of plastic on seabirds and dolphins. The message is clear: we need...

This video provides an overview of whales, the largest marine mammals in the world. It explores their size, feeding habits, communication methods, mating behaviors, and the importance of whales in the marine ecosystem. The video also...

This video provides an overview of seals and sea lions, highlighting their diverse species, habitats, behaviors, and reproductive strategies. It explores their role as top predators in the ocean and emphasizes the importance of these...

Polar bears are actually considered marine mammals, sporting partially webbed feet and swimming up to 30-60 miles across open ocean.

We are almost through the Phanerozoic eon! After the Paleozoic and Mesozoic Eras, we get to the Cenozoic era, which is the one we are still living in today. This is the age of mammals, which came to dominate the Earth, and here we also...

Dr. Kate Charlton-Robb is the Founding Director and Head of Research at the Marine Mammal Foundation. With over 16 years experience researching dolphins across southern Australia, Kate achieved a Bachelor of Science with a double major...
