The ability of an organism to change its characteristics in response to environmental variations is known as pheno-typic plasticity and is a key factor in the evolution of a species. eg; If a Holly finds its leaves are being eaten by herbivores it switches genes to make them spiky when they regrow. So on taller Holly trees the upper leaves which are out of reach have smooth edges, while the lower leaves which where previously eaten and have regrown are prickly.

The moth that could star in a horror film!
You might think this creature is out of a sci-fi movie, but it’s actually a real moth called Creatonotos gangis, or Australian horror moth. But the most amazing feature of this moth is its coremata. These are four long, hairy organs that the male can extend from its abdomen during mating season. The coremata are filled with air or blood, and can be longer than the moth’s body. They also produce a powerful pheromone that can attract female moths from far away. The pheromone is so strong that it can also repel predators who might find the moth too smelly to eat.

The Sailing Stones of Death Valley.
Sailing stones (also called sliding rocks) are part of a geological phenomenon in which rocks move along Death Valley in California. The movement of the rocks occurs when rain or snow fills the valley floor and creates a shallow pool of water. Then, when night comes, the temperature drops below freezing and a thin layer of ice forms on the water. The next day, the ice melts and breaks into big floating panels. These panels get pushed by gentle winds which push the rocks steadily forward. Some stones move from 2 to 6 meters per minute or about 6.6 to 19.7 feet per minute. Remember, these conditions are rare and only happen for a few days or weeks every few years. But it does happen.

The heart of a blue whale, which can weigh in excess of 1,300 lbs (590 kg) and is the size of a small car. The gigantic heart beats 8 to 10 times per minute and each heartbeat can be heard from over 2 miles (3.2 km) away. Their arteries are so large that a full adult size human can swim through them.

An ostrich is definitely slower than a cheetah, but they have stamina on their side. An ostrich can run pretty much full tilt for 15-20 minutes straight. Helps in situations like these.
