Angling from the water’s surface, the six-spotted fishing spider (Dolomedes triton) hunts and eats fish, tadpoles, and other invertebrates. It can even dive 18 cm (7.1 in) down into the water to complete the job. It is one of eight families of spiders that eat fish, and according to this PLOS ONE research, “fish predation by semi-aquatic spiders is geographically widespread, occurring on all continents except Antarctica.”
