Naturalists Information I

Some Interesting information a keen Naturalist should be aware of...

We may have come across this, but never know how to differentiate them. Karthik, the all-rounder and highly knowledged person threw some light on this enlightening us people at the NTP camp held by him.

Let me see if I can add some pictorial representations to this so that it becomes all the more easier deciphering and dissolving these in to our minds.

Here, I'm highlighting differences between closely related species. Suggestions, Inputs and Knowledge sharing are welcome :)

  • Newborn hares can immediately move around while newborn Rabbits cannot
  • Rabbits are not found in India.
2. Macaque and Langur
  • Macaque's stuff their food in cheek pouches while Langur's don't
  • Langur's are only leaf eating animals.

  • Centipedes are poisonous, non vegetarian and a little flat in appearance
  • Centipedes have 1 pair of legs per segment
