1. Lizards



Melanistic Eastern Blue Tongue Skink (Tiliqua scincoides scincoides).

3. Lion



In recent weeks, two very stunning black lion photographs have been circulating online. Why they attract such interest is that according to mainstream zoology, black lions

simply do not exist. If they did, and were wholly black in colour, they would most probably be melanistic specimens; analogous if not homologous genetically with black panthers

(melanistic leopards) and mutant all-black individuals of other felid species.
 
Sadly, for those hoping that these two photos therefore represented some major cryptozoological discovery, the reality, as is true ever more frequently nowadays, is that they

are nothing more than Photoshopped images.

5. Penguin



An extremely rare all-black penguin was photographed near Antartica by Andrew Evans of National Geographic. The king penguin doesn't look like his tuxedoed counterparts because

of what one scientist described as a “one-in-a-zillion kind of mutation.”
