Birdeaters and mouse catchers: spiders preying on vertebrates

Image
The darkest of nights: midnight in the Brazilian rainforest. At ground level, the jungle is dusky even during the day, when sunlight barely peers through the dense canopy; after sunset, though, it is pitch black. A rustle in the leaves; a predator on the prowl. Perfectly equipped for night hunting, he navigates the inky darkness with ease. The three-striped opossum may only be as big as a mouse, but he is nonetheless a bug's worst nightmare.

These animals were not being handled, and this is not something I encourage or condone. The live cone snail being handled is not a medically significant species, and not something that should ever be replicated without the necessary knowledge and experience (handling of medically significant cone snail species is extremely dangerous and potentially deadly)  It's definitely one of the most commonly sh...
