If sea slugs take ‘eternal energy’ from algae, can we?

Certain sea slugs suck raw materials from algae to provide a lifetime supply of solar-powered energy, according to new research. That’s kind of like attaching...

We know more about the surface of the moon that we do about the bottom of the ocean. The sea floor is an alien landscape,...

Marine fish won an evolutionary lottery 66 million years ago

Why do our oceans contain such a staggering diversity of fish of so many different sizes, shapes and colors? A UCLA-led team of biologists reports...

Rising sea levels put Pacific salt marshes at risk for extinction, study finds

Ocean’s deepest fish thrives 26,000 feet below surface

The ocean’s deepest fish doesn’t look like it could survive in harsh conditions thousands of feet below the surface. Instead of giant teeth and a...
Why are There No sea Snakes in the Atlantic

Why are there no sea snakes in the Atlantic?

Sea snakes are an evolutionary success story. With about 70 species, they're the most diverse reptile group in the ocean, outnumbering sea turtle species...
