Biologists have found a spider, fish-eating

Zoologists from Australia and Switzerland found several species of spiders who eat fish in excess of their size twice.

Martin Nyffeler from University of Basel and Bradley Puse from the University of Western Australia found five families of spiders that were hunting for fish exceeding the size and weight of the insects in half. Spiders perfectly swam, dived, and could glide on the water surface. The presence of powerful neurotoxins and enzymes enabling them to kill and digest various types of fish. These so-called semi-aquatic spiders typically dwell at the fringes of shallow freshwater streams, ponds or swamps. "Finding such a large diversity of spiders engaged in fishing and hunting is new," said Nyffeler.
