Trachelidae
Trachelidae, also known as tailless whip scorpions, are arachnids belonging to the order Amblypygi. They are characterized by their long, slender pedipalps, which they use to sense their environment and capture prey. Trachelidae species are typically nocturnal and have poor eyesight, relying instead on their highly sensitive pedipalps to navigate their environment. They are found in tropical and subtropical regions around the world, and while they are not venomous, some species can deliver a painful bite if threatened. Trachelidae species are also known for their unique courtship behaviors, which involve complex movements and vibrations of their pedipalps. Overall, Trachelidae species are fascinating and understudied arachnids that play an important role in their ecosystems as predators.
