Trioceros camerunensis is one of the rarest chameleon species known; it is almost unknown and only a few museum specimens exist. It has been depicted only a handful of times, so almost no one knows what it looks like in life. Its biology remains a mystery. This article presents a comprehensive overview of the species, synthesizing systematic classification, morphology, biogeography, and detailed captive husbandry based on firsthand breeding experience. T. camerunensis occurs exclusively in lowland rainforest habitats, unlike its montane relatives, and has been observed in nature only three times over two decades. Captive protocols derived from closely related Trioceros montium provide viable husbandry guidelines. This synthesis contributes new context to a species long overlooked by science and invites greater interest in its conservation.
