Brian - a spider.

Naukowcy w Australii odkryli nowy gatunek pająka. Jest to pająk wodny, który na powierzchni wody czyha na swoje ofiary. Zjada owady, kijanki a nawet  małe ryby. Brrrrrr..iiiiannnnn.
Scientists in Australia announced the discovery of a new species this week, Dolomedes briangreenei, or the Brian spider. This type of water spider waits on the surface until an insect, small fish, or tadpole comes near. The spider races to grab its quarry and then drags it to the shore to devour it.The spider was found around Brisbane and is thought to be endemic to Queensland. It is known to feed on tadpoles of the invasive cane toad , helping keep that pest in check.
