A. Tree squirrels are quite used to humans and many will come close to people hoping they will be fed. However, squirrels deserve our respectful distance. They have very sharp teeth and sharp claws and defend themselves by biting and scratching if they are startled. However, they are fun to observe. So treat them with gentle respect... and they can be wonderful 'wild friends'.
B. Elephants display 'right-handedness', not in their limbs, but in the tusks. Close examination of an elephant's tusks will reveal that one tusk has a blunter tip and is thicker than its less favoured counterpart. The reason for this difference is that in their natural habitat elephants use their tusks for gathering food, and digging for water. Consequently the tusk on their favourite side becomes more developed, but blunter.
C. In October 1987, an attempt to find a famous Loch Ness monster was made with 20 cruisers that swept the loch using sonar equipment, electronically recording all contacts. While the cruisers caught enough salmon to feed an army, there was no sign of Nessie. Most scientists would bet that there is no monster, yet they do seem to hedge themselves and keep an open mind as they await conclusive proof in the form of skeletal evidence or the capture of the monster.
D. Birds used for the production of Foie Gras are trapped in tiny cages, where they hardly have any place to move or flap their wings. Mechanized feeders come at regular intervals to feed them and metal pipes are forced down their gullets several times a day. The over-fed birds have difficulty breathing and acquire a range of diseases. Once these birds have reached a point of near-death, they are slaughtered, and their livers end up in restaurants!
E. Animals adapt over time to their environments, some so much so that they begin to look like their surroundings — a helpful evolutionary advantage in the face of potential predators (or while stalking prey). There are octopi that blend in perfectly with sandy ocean floors, insects that look just like leaves and fish that resemble oceanic plants. There is even an octopus that can mimic nearly twenty other oceanic species to scare off .
F. Humans work together all the time to build incredible structures we could never have dreamed up, let alone construct, on our own — but some animal architecture is arguably even more impressive. There is a spider web built by a variety of species working together that spans much of a public park, an ant colony that extends for thousands of miles and birds nests built by entire flocks living together under one thatched roof.
G. Raining animals... it sounds ridiculous, right? Nonetheless, it happens — although rarely. Fish, frogs and birds are the most common forms of animal rain. Sometimes the creatures land relatively unscathed but in other cases they are frozen or shredded to pieces. Theories vary in their details but generally it is assumed that certain kinds of strong winds lift up the animals with a volume of water (fish and frogs from ponds, for example) or sweep them out of the sky in the case of birds and then deposit them, often right before a major storm.
