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’.

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.

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. 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.

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.
