They live in burrows, often with a hinged trapdoor. This door is pushed up while the spider waits for passing prey. They rarely leave their burrows, catching prey and withdrawing as quickly as possible. Some of these burrows have side tubes. For the east-Asian genus Sinopesa it is uncertain whether it builds burrows at all. [6]
The trapdoor is hinged on one side with silk. The spiders typically wait for prey while holding on to the underside of the door. Prey is captured when insects, other arthropods, or small vertebrates disturb the 'trip' lines the spider lays out around its trapdoor, alerting the spider to a meal within reach.
Trapdoor spider is a common name that is used to refer to various spiders from several different groups that create burrows with a silk-hinged trapdoor to help them ambush prey. Several families within the infraorder Mygalomorphae contain trapdoor spiders: Actinopodidae, a family otherwise known as 'mouse-spiders', in South America and Australia
Cyclocosmia ricketti, like many other trapdoor spiders, dig burrows which are closed off by hatches in the ground instead of making webs (as they are not good at spinning silk) to catch their prey. [6] They line their burrows with silk threads and mud. They use their disk to plug the opening of the burrow. [6]
The “cryptic” animal was found along coasts of Taiwan, researchers said.
Ctenizidae (/ ˈ t ə n ɪ z ə d iː / tə-NIZZ-ə-dee) [2] is a small family of mygalomorph spiders that construct burrows with a cork-like trapdoor made of soil, vegetation, and silk. . They may be called trapdoor spiders, as are other, similar species, such as those of the families Liphistiidae, Barychelidae, and Cyrtaucheniidae, and some species in the Idiopidae and Nemesiid
Spiders spin webs to catch prey. They’re also trapping a wealth of genetic information. Katie Hunt, CNN. February 5, 2024 at 2:40 PM. Sign up for CNN’s Wonder Theory science newsletter.
The spider lunges out of its tunnel, above the insect, so it is able to catch its food using its fangs on the way back down. Unlike some spiders, Cantuaria do not wrap their prey in silk, but drag the victim into the depths of the burrow, with the trapdoor closing overhead. [12]
