Evolution
August 31st, 2010Evolution is what has kept many species from disappearing from the planet. Some have evolved in the right way quickly and have managed to share this world with their predators and other threats.
Here is a brilliant example of evolution. What you see is a caterpillar of the butterfly Blue Mormon, its very difficult for caterpillars to survive to become butterflies, given their susceptibility to predators. But this caterpillar in particular has developed different strategies to survive.
The eyes you see are false eyes and helps the caterpillar look like a snake. The face in totality looks similar to a snake, you would think this is enough to keep the predators at bay. But wait until you watch the video below.
This is how the caterpillar behaves when it senses threat, it pops out a ‘Y’ shaped organ that resembles a snake’s tongue. Called Osmeterium looks like a snake’s tongue to prevent a predator attack. That’s not all, this organ emits smelly compounds believed to be pheromones which are highly pungent in nature even to humans.
