Animals, mammals especially, don't often come in green but just as St. Patrick's Day comes around once a year, you can expect an unexpectedly green critter to make an appearance once in a while.

Green Horse

St. Patrick's Day green horse

Just look at this horse, it's in “mint” condition... yeah, that was bad and we feel bad, though maybe not as miserable as this once-proud stallion. Somebody give his owner a shake - and not one of the shamrock flavor. When asked about his unusual temporary tint, the equine reportedly replied, “Come on, folks, I'm dyein' out here!” (green animal image via Ali Eminov)     


Green Monkey

Green Monkey

Green monkeys are native to forested regions of west Africa and their fur is a greenish-golden color... except for one certain place. Indeed, according to the Wikipedia entry on this species, “males have a pale blue scrotum”. Females, presumably, do not. (green animal image via Asa Berndtsson)   


Green Pigs

Unexpectedly Green Animals

Political protest in Uganda is done a tad differently than what we're used to. Take these so-called “yellow pigs”, released onto Kampala's main street to raise awareness of high youth unemployment. Yep, this seems just the sort of thing high unemployed youths would do. (green animal image via RedPepper)          


Green Manatee

Unexpectedly Green Animals

Oh, the hued manatee! Sorry, couldn't resist. In any case, the above serene sea-cow sports a verdant carpet of algae on its back, not that there's anything wrong with that. Next time, pal, don't touch any new-fallen meteors after watching cheesy Stephen King horror movie anthologies. (green animal image via U.S. Fish and Wildlife Service)                


Green Rats

Green GFP Rats

Now why would scientists genetically engineer lab rats to express green fluorescent protein (GFP) derived from a jellyfish? Well sure, it's fun, but there IS a method to their madness: it's easy to know if the genetic modification worked. Hopefully this will lead to new treatments for genetic illnesses. Even more hopefully, treated patients won't glow green under UV lighting. (green animal image via ResOU)         


Green Sheep

These green-as-grass sheep from Bathgate are dyed-in-the-wool (pun intended) to raise awareness of Macmillan Cancer Support but there's an ulterior motive as well. “Our aim is to bring a smile to the faces of people around the world,” explained Niall Gibbons, chief executive of Tourism Ireland, “whilst also showcasing our wonderful tourism product to a global audience.” OK, but wouldn't the sheep showcase better if they didn't blend into the background? Just sayin'. (green animal image via JIM EASTON)              


Green Puppy

Forest, green puppy

As detailed by Creature Features previously, “Forest” was the only one of nine newborn Labrador Retrievers in its litter to come into the world green as a leaf o' lettuce. Forest's verdant fur will fade to its natural gold in time, since its hue is the result of a rare condition in which a green bile pigment from the mother's placenta imparts a distinctive tint to one or more of the fetal pups.

Green Sloth

Green sloth

Did you know that sloths' closest relatives are anteaters and armadillos? Thanksgivings must be a hoot around their house! Moss might not grow on a rolling stone but algae grows on a sloth's fur, so they've got that going for them, which is nice. These slow-moving primates have established a symbiotic relationship with one particular species of algae. We're not sure what the sloth gets out of the deal besides camouflage and free admission to punk rock concerts. (green animal image via Ian D. Keating)             


Green Polar Bear

Unexpectedly Green Animals

Algae can also grow on Polar Bear fur though this is mainly seen on zoo-residing bears in warm and humid countries. In contrast to a sloth's fur, algae can grow INSIDE polar bears' hollow hairs. This doesn't hurt the bears though it may deleteriously affect their endorsement deals with the Coca-Cola company. (green animal image via La Repubblica)                 


Green Cat

Unexpectedly Green Animals

We've featured this artificially-green cat from Varna, Bulgaria twice before – once in 2014 when it was VERY green (above) and again about a year later, noting then that most of the green had worn off. Seems this tinted tabby had been sleeping on a pile of powdered paint and was NOT the victim of cruel pranksters as many had assumed. Geez guys, they're Bulgarians, not barbarians!
