What sensory function do the hairs covering the wolf spider's legs primarily serve?
Answer
Detecting vibrations in the substrate during hunting activities.
The legs of the wolf spider are covered in hairs that function as crucial sensory organs. These hairs are highly specialized to detect vibrations transmitted through the ground or substrate. This seismic sensing ability provides the spider with essential early warnings or accurate distance readings about approaching prey or potential threats while it is running or stationary. This tactile input complements their visual senses, aiding in navigation and successful predatory tracking across uneven terrain.
