Trichonephila clavata, also known as the Joro-spider (ジョロウグモ, Jorō-gumo), is a spider in the Trichonephila genus. Native to East Asia, it is found throughout China, Japan (except Hokkaidō), Korea, and Taiwan, and has been spreading across North America since the 2010s. It rarely bites humans, and its venom is not deadly.
The Uraraneida are an extinct order of spider-like arachnids from the Devonian and Permian. [ 60 ] A fossil arachnid in 100 million year old (mya) amber from Myanmar, Chimerarachne yingi , has spinnerets (to produce silk); it also has a tail, like the Palaeozoic Uraraneida, some 200 million years after other known fossils with tails.
Araneus ventricosus walking on plant in South Korea [1]. Araneus ventricosus is a nocturnal orb-weaver spider [2] found primarily in China, Japan, and Korea [3] that has been involved in numerous research studies and is easily identified by its nocturnal web-building behavior. [4]
Spiders (order Araneae) are air-breathing arthropods that have eight limbs, chelicerae with fangs generally able to inject venom, [2] and spinnerets that extrude silk. [3] They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms.
The pedipalps have the typical arachnid structure with a coxa, trochanter, femur, patella, tibia and tarsus. They are pediform, i.e. they look like small legs and were not highly modified. [35] There is no evidence for a special sperm transfer device as in the modified palpal organ of male spiders.
An experiment proved the Jorō spiders' innate ability and involved the researchers placing the arachnids in wood frames, where the temperature was 22 degrees Celsius, for an entire day.
