According to CNET, spiders are often found in corners of houses, under outdoor benches or in bushes Lindsey swierk, a biologist at the State University of New York at Binghamton, recently observed a spider hiding underwater for 30 minutes
This impressive spider is fleeing humans and using a stream as a refuge. Swierk was published in [animal behavior] last month( https://onlinelibrary.wiley.com/doi/abs/10.1111/eth.13281 ) 》The lead author of a paper in the magazine on the spider's "diving" behavior.
According to the World spider catalogue, trechalea Extensa is distributed from Mexico to Panama and lives by streams. A 1993 study describing the spider said, "they can easily bite the collector's hand.". But the new study is to understand the spider's ability to survive in water.
Swierk said in a statement Monday at the State University of New York at Binghamton: "for many species, the risk of getting wet and cold to survival is almost the same as that of dealing with their predators. It was not known that trechalea spiders would avoid threats underwater - of course not for so long."
The secret of the spider's success in the water seems to be that the surrounding air "membrane" is fixed by hydrophobic body hair. Swierk described the spider as if it had been soaked in silver and thought the "membrane" might be to keep its respiratory openings away from water and possibly reduce the heat loss of the cold flow.
The spider's underwater exploration is an extreme measure to avoid being considered a threat. Further observation of the spider's unusual behavior can help scientists better understand how animals respond to predators.
