Scientists have discovered that many spiders prey on fish.
Spider has been regarded as the natural enemies of insects, but a new study shows that many live near water spiders prey on fish.
Sometimes, the use of deadly spider venom to kill much larger fish than they are.
The study was conducted by the research group cooperation Switzerland and Australia carried out, details of the study published in the academic journal PLoS One.
Martin Nyffeler University of Basel and the University of Western Australia Bradley Pusey recorded many common spider fishing scene.
Their evidence: It has been observed up to five families of spiders prey on fish in the wild, in addition, there are three sections of the spider can prey fish under laboratory conditions.
These semiaquatic spiders typically stay on the edge of shallow freshwater streams, ponds or swamps.
Some spiders can swim, snorkel or walk on water, and they often use a potent neurotoxin and enzymes to kill and digest larger and heavier than their fish.
On average, spider predator fish is twice as long as the spider predators.
"Our evidence suggests that the spiders diet, may fish only occasionally prey," said Dr. Nyffeler.
In addition to Antarctica, all continents have reported the existence of spiders prey fish phenomenon. In most cases recorded occurred in North America, especially in Florida wetlands.
Here, semiaquatic spiders often catch and eat small fish, such as mosquito fish.
To capture prey, the spider will usually stop on its hind legs on a stone or a plant, and its forelimbs resting on the water, ready to ambush.
Before eating process begins, the fish would be dragged dry place. This usually lasts a few hours.
