Spiders that spin webs typically have three claws, the middle one being small; hunting spiders typically have only two claws.

[6] Some spiders, such as the Australian crab spider, do not have claws.
The males of the species have light brown abdomens with dark brown stripes, USA Today previously reported. The spiders are golden orb-weavers, meaning they create webs with a slightly golden ...
Carnivores have chelicerae that tear and crush prey, whereas herbivores can have chelicerae that are modified for piercing and sucking (as do parasitic species). In sea spiders, the chelicerae (also known as chelifores) are short and chelate and are positioned on either side of the base of the proboscis or sometimes vestigial or absent.
Ant-mimicking spiders face several challenges: they generally develop slimmer abdomens and false "waists" in the cephalothorax to mimic the three distinct regions (tagmata) of an ant's body; they wave the first pair of legs in front of their heads to mimic antennae, which spiders lack, and to conceal the fact that they have eight legs rather ...

In spiders, the coxae frequently have extensions called maxillae or gnathobases, which function as mouth parts with or without some contribution from the coxae of the anterior legs. The limbs themselves may be simple tactile organs outwardly resembling the legs, as in spiders , or chelate weapons (pincers) of great size, as in scorpions .
The website JoroWatch monitors where Joro spiders have been spotted around the United States. According to the site, they have appeared in states like North Carolina, South Carolina, Georgia ...
