Males of the huntsman spider Heteropoda venatoria have recently been found to deliberately make a substrate-borne sound when they detect a chemical 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.
Heteropoda venatoria is a species of spider in the family Sparassidae, the huntsman spiders. It is native to the tropical regions of the world, and it is present in some subtropical areas as an introduced species. Its common names include giant crab spider, pantropical huntsman spider or cane spider. [1]

Members of this genus most closely resemble those of Heteropoda, except that the cephalothorax is high, peaking between the midpoint and the eyes, before sloping toward the back. This angle causes the front of these spiders to appear more prominent than ...
