Melanism is the increased development of the dark-coloured pigment melanin in skin/hair, caused by a recessive gene. Though it is reasonably common among wild cats – it has been reported in around a third of the 40 known species, including leopards – the trait is relatively rare in servals.
In this species it primarily occurs in East Africa, particularly in highland regions above 2000m. Some experts believe environmental conditions play a part. The high altitude (and forested habitat that comes with it) at which the serval usually operates reduces its exposure to daylight, which could encourage melanism – potentially ering camou lage as it hunts. In sunnier habitats, such as the Serengeti, melanism is unlikely to occur since a black coat could overheat the animal. Which is what makes this Serengeti sighting particularly unusual. At around 1000m, the Namiri Plains are considerably lower than the normal altitude where melanism is more prevalent. It is thought this particular cat (named Manja after the Asilia Africa guide who irst spotted him) may have travelled from the nearby (and much higher) Ngorongoro Crater and established his territory here. Either way, if a black cat crosses your path here – count yourself lucky.
