tarantulas including the Avicularia that are attached to the spider's cuticle ''via'' a stalk. These spiny, barbed hairs are used as a defense against potential intruders as well as embedded into silk to protect the egg sac. In active defense, the hairs are released by contact with the stimulus and rubbed in.
At least three species of Avicularia are threatened by habitat loss and illegal trafficking, due to their popularity as exotic pets. '' Avicularia avicularia'' are among the tarantulas most commonly kept as pets for their "stunning" color and size.
