Slit sensilla

The slit sensilla, also known as the slit sense organ,

physical deformation or strain due to forces experienced by the animal.^[2] The organ appears in the vast majority of discovered arachnids, and is "remarkably consistent" in location and direction within each order. The arachnid slit sensilla corresponds to the campaniform sensilla found in insects.^[1]

Slit sensilla tend to be widely distributed over the arachnid's exoskeleton,

electrostimulation on such arachnids can be easily recorded.^[3] Etymologically, "slit sensilla" are so named because they resemble a channel penetrating through the exoskeleton into the animal; despite this appearance, however, investigation has shown that slit sensilla do not actually penetrate the chitin

of the exoskeleton, but merely represent a thinning of the material.
