The camelthorn tree is the favourite living quarters of the black-tailed tree rat (Thallomys nigricauda) one of only 2 species of tree rats found in Namibia. Groups of 2 to 8 nest in holes and cracks in and between the main stems of trees. A mass of untidy twigs, grasses and leaves are often assembled to protect the entrance to the hole.

Predators include snakes such as the Cape cobra which find their way into the nest during the day. Owls follow suit but at dusk and black-tailed rats will escape out of any hole, falling to the ground or darting to higher branches to safety.
