The creature you see above is a spider that can actually surf on top of waves and hunt for a wide variety of animals including not only insects but also fish and toads. Dubbed the
Dolomedes briangreenei, this species of spider floats on top of water and senses vibrations below to detect potential prey. The spider can even submerge itself underwater for up to an hour to hunt down prey, which makes it doubly frightening for any creatures caught in its path. The largest animals that the spider has been known to eat are
cane toads, which can measure up to nine inches in length. For comparison, the
D. briangreenei is about the size of a human palm.
