Bat-eating spiders, Found Everywhere

Bat-eating spiders, There is the only place in the world to escape bat-catching spiders: Antarctica. These arachnids ensnare and pounce on bats everywhere else in the world, researchers say. Bats rank among the most successful groups of mammals, with the more than 1,200 species of bats comprising about one-fifth of all mammal species. Other than owls, hawks and snakes, bats have few natural enemies. Still, invertebrates — creatures without backbones — have been known to dine on bats. For instance, giant centipedes in a cave in Venezuela were seen killing and eating bats, and the arachnids known as whip spiders were spotted feeding on dead bats in caves of the Caribbean. Cockroaches have been observed feeding on bat pups that have fallen to the floor of caves.

Still, spiders are known to occasionally dine on a variety of vertebrates — creatures with backbones. For in

Bat-eating spiders, Most Terrifying Creature

Bat-eating spiders, A bat’s enemies: owls, hawks, snakes, the Joker, spiders. Spiders? Yes. The incidence of spiders eating bats could be more widespread than initially suspected, reports a study published March 13 in PLoS ONE. To reach this conclusion, the authors spoke with scientists, conducted an extensive scientific literature review, dug through the blogosphere, and looked for pictures of spiders eating bats on Flickr. Adult Proboscis Bat ( Rhynchonycteris naso ) entangled in a web of Argiope savignyi at the La Selva Biological Station, northern Costa Rica (photo by Mirjam Kn√∂rnschild, Ulm, Germany). The search turned up 52 reports of bat-eating spiders, less than half of which had been published before. The authors report that bat-munching spiders live on every continent except Antarctica. Most catch bats in webs, like the giant golden silk orb-weavers (Nephilidae). As adults, these spiders’ leg spans can be 10-15 centimeters across, and they weave webs more tha
