Brachionopus annulatus

B. annulatus is a terrestrial tarantula species known for its burrowing behavior. They create silk-lined burrows in the ground for shelter. Female individuals typically measure around 6 cm in body length, while males are smaller, averaging about 4 cm. Their carapace and legs exhibit a dark brown base color adorned with distinct pale bands or annulations, which inspired their species name "annulatus," signifying ringed or annulated. These tarantulas possess urticating hairs on their abdomen, which they can release as a defense mechanism, causing irritation when in contact with skin. Mature males actively seek out females for mating purposes. After mating, females lay a substantial number of eggs, typically ranging between 100 to 200, within a silk egg sac that they guard within their burrow. Although their venom is not considered medically significant to humans, a bite from B. annulatus can still induce considerable pain. In summary, B. annulatus is a medium-sized tarantula species native to South Africa, distinguished by the pale banding pattern on its legs.
