Soares and her colleagues used high-speed cameras to film a group of nine male guppies from the island of Trinidad. Their research, published online April 16 in the journal PLOS ONE, suggests wild guppies use their curious jumping ability as a way to spread the species away from an original habitat, to a new place with fewer predators. In other words, jumping likely serves a crucial evolutionary function for guppies.

The Robot VS The Drunk Fish

With some help from a robotic fish, scientists have discovered that zebrafish are much like humans in at least one way – they get reckless when they get drunk. OK, "drunk" might not be technically accurate, but when exposed to alcohol, the fish show no fear of a robotic version of one of their natural predators, the Indian leaf fish. When they're "sober," they avoid the thing like crazy.

Fish Uses Oyster Shells as Speakers

A clever fish has figured out that if it produces sounds in an oyster shell, the noises will carry over long distances, according to new research. The study, published in The Journal of Experimental Biology, is just the latest to show that fish are far from being silent. Many can produce sounds by vibrating their swimbladders and, like a fishy form of Morse Code, they can create different meanings based on the sounds.
