Video: It was the underwater match of the year. A swimmer crab and a red octopus squared off in mortal combat while divers circled round for a first-hand look at the coliseum spectacle nature had arranged for them. A tense battle played out as the two foes circled each other and kicked up a disorienting dust-cloud in their wake. But this sparring match would not end the way either of the opponents had intended.

Asteroid mining has gained steam in the popular psyche: who doesn't love the idea of flying up to one of the giant rocks flying by and somehow harvesting it of its precious metals like platinum. But today at the 2017 meeting of the American Association for the Advancement of the Sciences, scientists considered whether we should pursue another, far more likely alternative: mining the seafloor.
We already knew the deep ocean is full of nightmare creatures — twisted amalgams of tooth, jaw and fin sprung to life from some tortured corner of the multiverse. But good news — it gets even weirder! Scientists have just learned that one deep sea predator has a flexible attachment between its head and its skull that allows it to snap its jaws open like a Pez dispenser.
As currents shift in the southeastern Pacific Ocean, they bring an abundance of nutrients and plankton to the region, luring predators of all sizes. Swarms of anchoveta arrive first for an easy meal, but soon find themselves having to come up with unique ways to fend off larger predators like sharks and tuna. The result should be familiar to fans of the popular B-movie Sharknado.
As if the ocean wasn't already full of nightmares, researchers at MIT have developed a soft and flexible robot made of hydrogel, a material composed mostly of water. The new bot is quick, strong and almost completely invisible when submerged, allowing it to snatch up fish before they even realise they're being tracked.
Animals, like humans, communicate in lots of different ways. One of those ways, in animals as in humans, involves urinating on one another.
