3. Green Sloths
Sloths sometimes appear to be green because their fur is an ideal environment for blue-green algae. Unlike most fur-bearing animals, sloths’ fur will absorb water, which encourages algae to grow and impart a green hue.

6. Orange Crocodiles
In late 2011, Snappy the crocodile surprised his handlers by suddenly turning orange. The reptile experts at the Roaming Reptiles Park in Australia attributed the change to a broken filter; Snappy had attacked it prior to his dramatic color change, and handlers suspected that iron or tannins in the water were responsible. No harm came to Snappy after he turned orange. Coincidentally, an orange alligator was sighted earlier in 2011.
7. Pink African Grey Parrots
Pink patches in African Greys (which, as you might guess, are normally grey) began as a naturally occurring color morph. Over the years, breeders ended up with 100% pink specimens. The first all-pink Greys sold for over $150,000.
8. Metallic Green Bees
When we think bees, we think yellow and black stripes. But in reality, bees come in a variety of colors, including red, blue, and green. Bees in the genus Agapostemon are not only green, but shiny. If you can stand the joke: green sweat bees are the shiny Pokémon of the bee world.
