Scorpions
Scorpions are among the most popularly known arachnids, being easily recognized by their post-abdomen or metasoma (tail), which has a sting (aculeus). Their pedipalps are shaped like pincers called chelae. Despite the fact that they appear to have two eyes, most scorpions actually have eight eyes. They are nocturnal, and always go out to hunt at night. Most scorpions in the Manaus area don’t pose a threat to humans, although accidents with one of the species may require medical attention.
