Genetic mutations sometimes occur in lobsters, producing a protein in excessive amounts, giving them a brilliant blue outer shell. Photo: Flickr

The tigers are white due to the rare skin pigmentation variation of the Bengal tiger. However, a common misconception is that white tigers are albino. Unlike albino individuals, white tigers still produce melanin. Biologists call it “natural phenotypic variation”, a dominant genetic variation in the Bengal tiger population. Photo: Shutterstock

Piebaldism is a rare disease in animals that affects the ability to produce melanin pigments that give skin its color. This phenomenon causes pythons to have very strange colors due to white pigment groups mixed with normal skin color. Photo: Shutterstock

Strawberry leopards at the Madikwe conservation center, South Africa, are characterized by blond spots, due to their excess red pigment. Photo:  Shutterstock

The Katydid pink grasshopper is a rare species. Their stems are not green but pink. However, this makes them stand out and easy to detect. Photo:  Flickr

Pandas have mainly black and white fur. However, scientists discovered individuals with brown fur instead of black. NTDTV/YouTube

Some penguins have completely black feathers because they have melanism (the opposite of albinism). Instead of lacking skin pigmentation, these animals contain dark spots covering their entire bodies. Photo:  National Geographic/YouTube

Zebras can have yellow stripes due to amelanism, similar to albinism. In mammals, the symptoms of amelanism and albinism are virtually indistinguishable. Photo:  Flickr
