'Invisible' Black Leopard Spots Finally Revealed [PHOTOS]

Believe it or not, there is no true species of 'black panther' stalking the dark jungles of the world. Often, they are unusual variants of cougars, jaguars, or even leopards. This certainly holds true for the Malaysian black panther - leopards with sleek black coats and, oddly enough, invisible black spots. Now researchers have determined how to make the unseen seen - a boon for conservation.

"This is perhaps the only known example of a wild mammal with virtually an entire population composed of black individuals and scientists have no idea why it predominates in the Malay Peninsula," Laurie Hedges, a researcher with The University of Nottingham Malaysia Campus (UNMC), explained in a recent statement.

According to the scientist, all that's known about this coloration is that it's caused by melanism - a genetic tweak that causes the overdevelopment of the pigment melanin in the skin. The opposite of albinism, melanism is usually rare, randomly popping out all manner of black cats - from the lanky and iconic grey-and-black jaguar to the near-mythological black lion.

Stranger still, while the genetic information that carries melanism for jaguars is actually a dominant trait - leading to some exciting spotted cat colorations - the jet black panthers we see among Malaysian leopards (Panthera pardus) are the product of a recessive allele. (Scroll to read on...)

Sure these panthers might seem completely black, but they still are leopards - animals characterized by spot patterns as unique as snowflakes. Hedges and his colleagues theorized that because the black of these animals' spots would be different than their coats, they would reflect light differently. All that was needed to be done then, was to rig wildlife camera's to always use an infrared flash. And viola! Suddenly each and every leopard spotted looked... spotted!

"We found we could accurately identify 94 per cent of the animals," added co-author Gopalasamy Reuben Clements, of James Cook University. "This will allow us to study and monitor this population over time, which is critical for its conservation."

Now the researchers hope to use this technique to track individual black panther's in particular - learning about their ranges and perhaps identifying parts of Malaysia most heavily assailed by illegal poaching.
