Did you know that sea otters have the thickest fur out of any animal on Earth?

    While most animals in the sea utilize blubber to keep themselves warm, sea otters do not! They rely on their dense fur and high metabolism to live and stay comfortable. Their two-layered fur is about 1.5 inches thick, and the number of hairs they have can range from 500,000 to 1,000,000 per square inch! Humans have around 100,000 total. Sadly, their furs were sought after to use for coats and clothes for a long time, and their species was at risk of extinction. Through wildlife protection efforts starting in 1913, they were able to prevent this!

By using saliva from people who had just woken up, scientists were able to test saliva on wounded skin cells and found that little "nets" were found all over the cut.      " When you suck on a cut finger, white blood cells in your spit release an arsenal of weapons to defeat bacterial invaders. First, white blood cells can simply engulf the bacteria and die as martyrs. Or they can shoot bacteria with deadly substances that cause the bacteria to disintegrate. But white blood cells can also do something even cooler: create sticky, viscous “nets” and throw them out like lassos to capture and wrestle bacteria to their deaths." (R.E. Gross) Discussion Question: Why do you think that the spit used in the experiment had to be collected from people who had just woken up? For more information on the subje...
