Snails are sensitive to sun light. Thus, they prefer mild and humid atmosphere and comes out mostly in the dusk. When the environmental conditions are harsh, snails go into a state called hibernation and sleep for nearly 3 years. Snails crawl inside their shells and seal it with mucus when they go to this long sleep coming out only when the climate condition is tolerable.

Hummingbirds are the smallest known birds in the world. They are also the only birds who can fly backwards. They can turn their wings to an angle of 180 degrees and easily move backwards. Their highest wing-flapping speed per second is 80 beats and when they flap the hardest their heartbeat reaches up to 1260 beats per minute. The sound fast-flapping wings make is the origin of its name hummingbird.

But the sad truth behind this is, a Chimpanzee only shows all his teeth (especially upper raw teeth) when he is afraid of something. It is more than likely that Chimpanzees were scared at the moment the photographs were taken.
