The Latin name of Panthera leo krugeri is not limited to white lions. It applies to all South African lion subspecies; the prides of which are mostly located in Kruger National Park and nearby game reserves.
White lions are not albino as they have pigmentation which shows particularly in eye, paw pad and lip colour. The correct term for their condition is leucism, a state where there is near-normal eye colour, but loss of pigment in the skin and fur.
The cause of the unusual colouration is the same as for the white tiger. A recessive gene which results in the white appearance is found in a very small number of captive lions.
White specimens usually have a yellowish-brown or golden eye color which is very similar to their tawny cousins, though some have bluish coloring like the white tiger.
