Evolution

31/08/2010

Evolution 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.

Malabar Pit Viper

28/07/2007

Vipers are venomous, and the malabar pit viper is endemic to the western ghats as the name suggests. These are nocturnal hunters and bask and laze around during the day. The pit vipers get their name from the pits (the holes that look like nose), which are heat sensing, which helps in detect warm-blooded animals like rodents & birds in absolute darkness.

Back from the western ghats…

25/07/2007

Just got back from kudremukh, the place is just beyond words in the monsoon. Got tons of leeches so feet is still recovering. Got to shoot one of the most dangerous reptiles in western ghats, a viper. Had no luck on the Lion-tailed macaque, though we drove for 2 days on the park roads. Pictures coming soon :)
