With some pale brown to grey on the lower segments, though some darker specimens have been registered. Observation from captive individuals have shown their egg sack to be about 220 eggs.[1][2]

This spider is thought to have been widespread across Montserrat, although most of it has been lost, it mainly inhabits natural areas, and those whom have been heavily modified. The main deciding factor of this tarantula living area is the substrate, as a burrower it needs to well burrow, and its believed this tarantula is widespread across Montserrat.[1][2] Montserrat has average temperature are about 27°C, and the average yearly rainfall is 1600mm, the climate being subtropical.[3]

This zoo managed to breed this tarantula in 2016, and they are being observed to understand their lifespan.[1] This tarantula have had some problems with their habitat, as invasive species, development and the volcanic development are major threats to this spider.
