Which animal has the densest fur, try to guess
|
view preview
With up to one million hairs per square inch of its body, the sea otter has the densest fur in the animal kingdom. (To put this in perspective, you’ve probably only got 100,000 hairs or less on your whole head!) Together with a huge lung capacity, this makes these water-loving creatures extremely buoyant. The pups are born so buoyant, they're incapable of diving underwater, and are often left bobbing on the surface in a sea kelp bed while their mothers hunt for food nearby.

Why do men have bigger noses than women?
|
view preview
Men’s noses are 10% larger than female's. Males generally have leaner muscles and need more oxygen for muscle growth and maintenance—and larger noses mean more oxygen can be breathed. A new study found that the difference in nose size between males and females of European descent starts showing in early puberty, when 95% of body weight gain in males comes from fat-free mass, compared to 85% in females.

Shock-absorbing goo found within bones
|
view preview
A viscous fluid made out of citrate and water is what gives our bones flexibility. The gooey fluid is trapped between the tiny crystals of calcium phosphate that form our bones, absorbing shocks and allowing movement. Without this fluid the crystals fuse together and become less flexible and brittle.

Drinking seawater to survive
|
view preview
A seagull on a glass roof looking really cute. Seagulls are able to drink seawater to survive thanks to salt glands just above their eyes. These glands eliminate excess salt from the seawater and flush it out of the birds' nostrils in liquid form, an action that's often mistaken for a sneeze.
