Huntsman spiders (formerly Heteropodidae) (Juvenile )
They are known by this name because of their speed and mode of hunting.They are also called giant crab spiders because of their size and appearance. one of the huntsman spiders that seems to easily find its way around the world, have recently been found to deliberately make a substrate-borne sound when they detect a chemical (pheromone) left by a nearby female of their species. The males anchor themselves firmly to the surface onto which they have crawled and then use their legs to transmit vibrations from their bodies to the surface. Most of the sound emitted is produced by strong vibrations of the abdomen.
