The newly discovered spider called the dolomedes briangreenei hails from, you guessed it, Australia.  One of it's species, whose name is Brian, was presented at the World Science Festival in Brisbane. 

He was named after Professor Brian Greene, cofounder of the World Science Festival and a string theorist. 



Brian (the spider, not the string theorist) uses vibrations in the water to fish. Robert Raven, Principal Scientist of Arachnology at the Queensland Museum told Mashable:

These spiders sit there on the water and then all of a sudden an insect will hit the water and the spider races out to get it, grabs it, dives under the water and then swims back to the shore and starts eating it. 


It eats insects, fish and toads up to three times it's own size. Apparently its bites aren't that dangerous but the fact remains; now even the water is not safe from spiders.

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.

MSU scientists have made a number of improvements on the fish, including the ability to glide long distances, which is the most important change to date. The fish now has the ability to glide through the water practically indefinitely, using little to no energy, while gathering valuable data that can aid in the cleaning of our lakes and rivers.
