The film shows two fights between males of Admetus pumilio from Pará, Brazil. At the beginning of agonistic behaviour the animals are tapping each other with their antenniform legs. It follows the "fighting with the antenniform legs" in which the animals are standing as far apart as possible and each is tapping its opponent with one antenniform leg. Soon the "final fight" follows. The animals step foreward, their pedipalps maximally unfolded, and each one tries to grasp at its opponent with its pedipalps. This fight is very fast and vigorous. However, the agonistic behaviour is formalized and no damage results. After the fight, the inferior animal avoids another confrontation and tries to get away.
