It’s not an unusual sight out in the ocean: blue whales slurping up clouds of krill. But researchers most often have a boat’s eye view for this event. Now new drone footage from Oregon State University is giving them a whole new perspective on how these massive creatures, the largest animals on the planet, catch their dinner.
Prey animals are capable of defending themselves in an amazing of ways, but when it comes to mounting a sophisticated biological counter-attack, sea urchins have taken it to another level. When attacked by predatory fish, these humble echinoderms release a hostile cloud of tiny jaws that act independently of the urchin itself, attacking the fish and releasing the venom contained within them.
We tend to think of coral reefs as luminous, undersea jungles that pepper the shallow, scuba-friendly tropics. But deeper down, in a region about as bright as Pluto on a sunny day, there lie vast reef ecosystems unknown to science.
There are thousands of ships sailing the seas to catch the fish you eat, and now you can watch them sail the ocean in almost real-time on this interactive map.
The sixth mass extinction—the one that seven billion humans are doing their darnedest to trigger at this very moment—is shaping up to be like nothing our planet has ever seen. That’s the conclusion of a sweeping new analysis, which compared marine fossil records from Earth’s five previous mass extinction events to what’s happening in the oceans right now.
Having whetted our appetites with two earlier iterations of their Floating Seahorse luxury homes (long since sold out), Dubai developer Kleindienst has just launched their latest watery wonder: The Signature Edition.
The oceans have been acting weird lately. While some sea creatures have boomed (octopuses), others have busted (humpback whales), and yet others literally melted into goo (starfish). Whether the causes are El Niño or the “Blob” or ultimately climate change, these events point to just how interconnected and poorly understood the ocean ecosystem is—how little of it observable by humans. A marine biologist who studies whales once likened finding a beached one to finding a specimen of a “space alien.” The sea is dark and full of mysteries.
