Haplopelma sp. “BaKan” (now often referred to under the genus Ornithoctoninae) is a medium-large fossorial tarantula native to Southeast Asia. This species is recognized for its robust burrowing habits, dark brown to black coloration, and strong defensive posture when disturbed.
Behavior and Temperament: Highly defensive and quick to retreat into its burrow; not recommended for handling. Will rear and display if disturbed. Typical of Old World spiders, it relies on biting rather than urticating hairs for defense.
Habitat and Environment Needs: Requires deep substrate (at least 15–20 cm) for burrowing and humidity around 75–80%. Moderate moisture preferred, not soaking, but often misted or dampened, with deep dry retreats to avoid fungal issues.
Feeding: Eats live insects such as crickets, roaches, and other feeder bugs. Young slings typically fed 1–2 times per week; adults can be fed every 7–14 days depending on size and appetite.
Additional Information: Originally sold as Haplopelma sp. “Bakan”, now often classified in the genus Ornithoctoninae. Like other genus members, it utilizes silk-lined burrows with hidden turrets and signal threads at the entrance.
