Ceratogyrus darlingi (Rear Horned Baboon)
What sets this species apart from most, and makes it unique to many collections, is the black horn that grows in the center of its carapace. The horn on the C. darling is curved, unlike that of the C. marshalli, which is straight. Foveal horns are seen in many species within the Ceratogyrus genus. This formidable species is known to be aggressive, a trait common to African species. Great care should be taken with this fast spider.
But what the heck is that horn for? Well, no one seems to know for certain, but as is referenced below, Rick West suggested that the horn may give this tarantula a greater ability to eat more quickly by increasing its ability to draw up liquefied food. It may also allow it to take in more nutrients and water.
