The binturong, or bearcat, is a rare species found in Southeast Asia. The females are usually 20% larger than the males, and they communicate amongst themselves using scent glands located on either side of the anus. These scent glands emit an odour that smells exactly like buttered popcorn.

The sweat is actually about the consistency of mucus. It helps regulate body temperature and acts as an effective sunscreen.

Researchers studying a group of wedge-capped capuchin monkeys that live in tropical forests of central Venezuela have discovered that the monkeys protect themselves against the annual merciless onslaught of mosquitoes exactly as humans do: by rubbing themselves with mosquito repellent.

But while humans may reach desperately for spritzers or bottles or laughably overhyped ''protective'' skin-so-softeners, the capuchins have learned to poke around in tree bark or termite mounds to extract a wriggling specimen of Orthoporus dorsovittatus, a millipede rich with powerful defensive chemicals called benzoquinones.

The capuchin monkey will then proceed to anoint itself head to foot with the repellent secretions by massaging the four-inch-long millipe ...

Hemocyanins are proteins that transport oxygen throughout the bodies of some invertebrate animals. These metalloproteins contain two copper atoms that reversibly bind a single oxygen molecule (O2). They are second only to hemoglobin in frequency of use as an oxygen transport molecule. Unlike the hemoglobin in red blood cells found in vertebrates, hemocyanins are not bound to blood cells but are instead suspended directly in the hemolymph. Oxygenation causes a color change between the colorless Cu(I) deoxygenated form and the blue Cu(II) oxygenated form. ...

Did you know one quart of horseshoe crab blood costs $15,000 dollars?

The critter's blue blood is a sort of bacteria killing machine that clots around ‘invaders’, eliminating them and protecting horseshoe crabs from lethal infections. Researchers have been harnessing the power of this blue blood to test medical supplies for contamination.

This is the giraffe weevil from Madagascar, which, as you might have guessed, gets its name from its long neck. Males use their extra long necks for fighting, while females use theirs to roll a leaf nest, into which an egg is laid during reproduction.

Take a good look at this woman. She was created by a computer from a mix of several races. What you see is a remarkable preview of what the North American race will look like.
