Spiders are traditionally viewed as predators of insects. Zoologists from Switzerland and Australia have now published a study that shows spiders all over the world also prey on fish. The academic journal PLOS ONE has just published the results. Although viewed by ecologists as the classical predators of insects, researchers have become increasingly aware that spiders are not exclusively insectivorous. Certain larger-sized species supplement their diet by occasionally catching small fish.
This is showed in a new study by zoologist and spider expert, Martin Nyffeler from the University of Basel, Switzerland and Bradley Pusey from the University of Western Australia. The researchers gathered and documented numerous incidents of spiders predating fish from all around the world.
