The oceans transport heat around the globe, keeping the temperatures fairly mild across the entire planet. But a big change in ocean salinity could change that pattern, altering ocean currents and raising global temperatures.

That’s not likely to happen anytime soon. But it could be happening on planets in other star systems. And that could expand the range at which a planet can sustain life.

That range is known as the “habitable zone.” It’s the distance from a star where temperatures are just right for liquid water to exist on a planet’s surface.

Many predators hunt by camouflaging themselves and waiting for unwary prey to swim close enough to become a meal. One species of frogfish managed to hide from scientists, too. Only in 2015 did researchers rediscover this color-changing critter dwelling in tropical and subtropical waters and determine that it was an entirely new genus and species, Porophryne erythrodactylus. What makes frogfish such successful predators is their ability to completely blend into the sponges and corals where they lay in wait, so it’s incredibly difficult for unsuspecting prey to spot them.
