Most tarantulas can jump a few inches and typically pounce forward horizontally to catch prey, rather than leaping vertically. Some arboreal and tree-climbing species can jump farther, such as the Antilles pinktoe tarantula, which can jump up to 11 inches.
Although jumping spiders are not tarantulas, they are known for their ability to jump several times their body length. They accomplish this through their internal hydraulic system, which allows them to alter pressure in their body quickly and extend their legs forcefully enough to make large jumps without having muscular legs. Jumping spiders commonly leave silk tethers behind when they jump as a safety net in case they fall.
