Do Tarantulas Spin Webs?
Most spiders spin webs that serve as homes and traps for prey. These webs are spun from silk thread produced by protein reserves. Although tarantulas are also capable of producing silk, they do not use it for these purposes. Rather, tarantulas use silk to create door-like entrances to their burrows and to line their habitats, which are most commonly found underground or in tree and rock crevices.
The tarantula's silk acts as an alarm system, alerting the arachnid to the presence of threat outside its burrow. If the intruder is potential prey, the tarantula will capture and subdue it. Silk may also be utilized to form molting mats. These woven structures provide a resting place while tarantulas shed their old exoskeletons and wait for their new ones to harden. Tarantulas molt between two to three times per year.
A study published in 2006 indicates that tarantulas produce silk through spinnerets located on the feet, allowing them to scale vertical lengths. The impressive mobility of the tarantula may be attributed to this ability.
