Ecology of the true spiders (Araneomorphae) [1973]

To avoid being eaten by the females, which are typically much larger, male spiders identify themselves to potential mates by a variety of complex courtship rituals. Arthropods’ proprioceptorssensors that report the force exerted by muscles and the degree of bending in the body and joints, are well understood.
