The huntsman spiders build traps using silk and leaves to catch frogs and other large prey and then make a meal out of them.

A fishing spider waits on the water surface with its back legs anchored to the rocks or a leaf. When a frog passes by, it pounces on it and gets hold of it. It then injects it with its venom, which liquefies the internal organs which the frog then sucks out.
