SHORT COMMUNICATION Scopulate hairs in male Liphistius spiders: probable contact chemoreceptors
Adult male Liphistius have dense hair pads on the ventral side of their tarsi. At first glance they appear like the adhesive scopulae, which are well known from mygalomorph spiders. However, a fine structural analysis of these scopulate hairs shows that they lack the brush-like structure with tiny ‘‘endfeet’’ that is typical for such adhesive hairs. Instead, the smooth hair shaft exhibits a sma...
متن کاملThe Great Silk Alternative: Multiple Co-Evolution of Web Loss and Sticky Hairs in Spiders
Spiders are the most important terrestrial predators among arthropods. Their ecological success is reflected by a high biodiversity and the conquest of nearly every terrestrial habitat. Spiders are closely associated with silk, a material, often seen to be responsible for their great ecological success and gaining high attention in life sciences. However, it is often overlooked that more than h...
متن کاملTactile hairs on the postcranial body in Florida manatees: a Mammalian lateral line?
Previous reports have suggested that the sparsely distributed hairs found on the entire postcranial body of sirenians are all sinus type tactile hairs. This would represent a unique arrangement because no other mammal has been reported to possess tactile hairs except on restricted regions of the body, primarily the face. In order to investigate this issue further, hair counts were made systemat...
متن کاملNeural Processing of Auditory-tactile Sensor Data to Perform Reactive Behavior of Walking Machines
Spiders can sense sounds in a frequency range between approximately 40 and 600 Hz by the use of hairs; they can detect e.g. the puff of wind of buzzing flies. On the contrary, scorpions use hairs as tactile sensors for obstacle avoidance. To integrate the advantages of both types of sensoric hairs, this article presents an artificial auditory-tactile sensor system, which combines the principles...
متن کاملTactile body raising: neuronal correlates of a ‘simple’ behavior in spiders
This review summarizes our recent results on the sense organs, the central nervous elements, and the neuronal mechanisms responsible for a relatively simple, tactile behavior of spiders. In Cupiennius salei (Keyserling 1877) (Ctenidae), a large tropical hunting spider, stimulation of tactile hairs on the ventral aspects of the body and the legs evokes reflex activity in several leg muscles. Coo...
