The sun's UV-B radiation has less of a damaging effect on fish (yes, fish) who exercise (yes, exercise) more.
So, um, what does this mean for us? And why did this study occur in the first place?
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.
Animals, like humans, communicate in lots of different ways. One of those ways, in animals as in humans, involves urinating on one another.
Video: Damn, the ocean isn't here to play around. This worm, known as a sand striker, buries itself in the ground and can grow up to twice the length of a human. It has no eyes and no brain and yet it can snatch the body and soul (and everything else) of a fish from right out of the ground. It's like a terrifying death trap, shooting itself out from the floor and making the fish disappear in an instant. Damn.
Saving seaside real estate isn't the only business benefit of fighting climate change. Scientists think that adhering to the Paris Agreement could be crucial to the success of the commercial fishing industry.
Researchers have discovered that Atlantic killifish are now 8000 times more resilient to high levels of toxic waste than other fish, allowing them to survive extreme levels of pollution that would normally be deadly. It sounds like an evolutionary success story, but examples like this are exceptionally rare in the animal kingdom.
