How does the Brazilian Black Tarantula (G. pulchra) often differ in using urticating hairs defensively?
They have a reduced tendency to kick these hairs, preferring to flee
While nearly all New World tarantulas possess urticating hairs—barbed bristles that can be brushed off the abdomen to irritate an aggressor—the Brazilian Black Tarantula (*G. pulchra*) exhibits a notable behavioral difference regarding this defense. They are specifically noted for having a reduced tendency to employ this hair-kicking mechanism. Instead of immediately engaging in hair deployment when feeling threatened, *G. pulchra* often prioritizes avoidance, opting to flee rather than initiating a direct confrontation. This preference for flight, combined with their relatively milder venom compared to some other species, contributes positively to their reputation among keepers.
