|A Marozi or Spotted Lion (Panthera leo maculatus) is claimed to be a rare, natural hybrid of a leopard and lion or perhaps an adult lion which retained its childhood spots. It is believed to have been smaller than a lion but slightly larger in size than a leopard and lacking any distinguishable mane. Although it has been reported to be seen in the wild and the skin of a specimen exists, it has yet to be confirmed as either a separate species or subspecies.
While African natives have been familiar with the animal and Europeans have been reported seeing spotted lions since roughly 1904, the first documentable encounter by a European was in 1931 when Kenyan farmer Michael Trent shot and killed two individuals in the Aberdare Mountains region at an elevation of 10,000 feet. The unusual spotted markings on what seemed to be smallish adult lions prompted interest from the Nairobi Game Department; they were from pubescent lions and yet had prominent spots that are typical only of cubs.
Two years later, explorer Kenneth Dower headed an expedition into the region in an attempt to capture or kill more specimens. He returned with only circumstantial evidence: three sets of tracks found at a similar elevation as Trent's lions (10,000-12,500 feet). They were believed to have been left by individuals that were tracking a herd of buffalo during a hunt, ruling out the possibility of the marozi being cubs. Dower also discovered that the natives had long differentiated the marozi from lions or leopards, which they referred to by different names. Aside from that, he found out that the marozi had also been called different names in other regions, such as "ntararago" in Uganda, "ikimizi" in Rwanda, and "abasambo" in Ethiopia.
Besides this, there were other sightings around the same time:
Four animals sighted by Game Warden Captain R.E.Dent in the Aberdare Mountain region at an elevation of 10,000 feet.
A pair sighted on the Kinangop Plateau by G. Hamilton-Snowball at an elevation of 11,500 feet. They were shot at but escaped.
Lion/leopard hybrid: Lions and leopards hybridized in captivity have very closely resembled the descriptions of the marozi in both size and coat pattern. However, while captive hybridization of big cats is well documented, no such event has ever been recorded in the wild. Even if it could have happened, hybrid offspring are almost always sterile and that is unable to explain the fact that there seemed to be a marozi population in the region. Aside from that, the two species are natural enemies and live different lifestyles, so the chance of a naturally occurring hybrid is very small.
Genetic aberration: It is possible that the marozi was a result of a recessive gene that spread through a population of lions as a result of inbreeding. Big cats have been known to have their coats affected by recessive genes, as seen in black leopards (panthers), white tigers, and the king cheetah. A genetic mutation might result in the lion's juvenile spots being retained into adolescence or even into adulthood. This does not explain the smaller size of the marozi and its preferred habitat of elevated, wooded areas instead of the traditional savannah habitat of other lions. Interestingly, the Aberdare region is home to many endemic species and subspecies.
Sub-adult lions: The smaller size, the presence of spots/rosettes and the insignificant manes on males could indicate sub-adult specimens, possibly ousted from their prides.
New taxon: The marozi could have been a yet-undiscovered species or subspecies of lion. The answer to this largely depends on when, if ever, a closer inspection and DNA analysis is done on the skin of the Trent specimen.
Inspections of the Trent specimen conducted up till 1937 (now found in the Natural History Museum in London) have generally yielded the following observations:
5' 10½" (head and body only. Without tail).
Tail (without tuft) 2' 9".
Total length 8' 8".
Estimated age of 3 years (about 1 year from fully grown).
Insignificant mane, this being 5" at its longest point.
Distinctive irregular spots or rosettes over the flanks, shoulders and thighs. Not present down the spine.
Diameter of the largest spots: 85 by 45, or 65 by 65 mm.
Rosette colour across flanks: greyish brown with a darker centre.
Solid spots on the legs and abdominal area. Very obvious on the underbelly due to the pelage ground colour being paler. Less spotting on the hind legs than the forelegs.
A skull not belonging to the Trent lions but believed to belong to a marozi has also been found. The lower jaw is missing but the upper one has all the teeth intact. The sex is undetermined. It was not from a fully grown animal as the sutures were still open.
No reports of the marozi have surfaced from the Aberdare region since the 1930's and it is believed that the population has long since become extinct. Reports of spotted lions are still fairly common throughout other parts of Africa, though.
