Borneo Black Earth Tiger
The Borneo Black Earth Tiger (Phormingochilus sp.) is a tarantula endemic to the island of Borneo, named for its glossy black coloration. It is the type species of the genus Phormingochilus. While often still and secretive when undisturbed, it can bolt at surprising speed or snap into a strong threat display when it feels cornered. This mix of speed and defensiveness places it firmly in advanced-keeper territory, best suited to those who enjoy observing a more high-strung species from a respectful distance.
