When we think of bears, tigers, lions, horses, otters and other such common animals, we might believe nothing can surprise us anymore. After all, these animals are stars in many documentaries and we have even seen some of them ourselves. Despite all that, animals will always surprise us. Animals hide many unexpected secrets, some of them almost hard to believe. Discover here some fascinating facts about otters, polar bears and ferrets.
1. Otters have pet rocks
Otters are well known. Sea otters eat what they find in their environment: crabs, mussels, clams. In order to crack open the shell of their prey, otters use rocks. They bash them repeatedly on their prey of choice until the shell is cracked open. Mind it: not any rock will do!
Otters search around and choose only certain rocks. These are their favorites and they keep them in pouches of skin under their forelimbs. Those rocks are never thrown away. We can certainly say they are similar to “pet rocks.”
2. Polar bears have black skin
We would probably think that polar bears have pinkish skin similar to that of many animals. Wrong! Polar bears have, in fact, a black skin. This helps them absorb as much heat as possible under the Arctic sun. In addition, these bears have a layer of fat which can be as thick as 11cm. It helps them survive in the most frigid conditions.
3. Female ferrets can die if they do not find a mate
Ferrets are adorable creatures. Some people keep them as pets while others admire them from afar. They are well known animals and you would think nothing could surprise you about them. Still, did you know that female ferrets can die if they do not mate? In heat, their body secretes high levels of estrogen. If this estrogen remains in the body for too long it can attack the bone marrow. In turn this leads to life threatening aplastic anemia.
