Blind Earthworm

I never paid much attention to the earthworms previously. Yeah, I used to see many of them particularly in the rainy season and sometimes digging the wet mud. We used to use them as bait for catching fish, but it never occurred to know more about them. Only recently I found them interesting, when I saw one of them going on the walkway in my apartment. I noticed it was blind and just to confirm it picked it up and displaced it by 180 degrees and there it was just following the new course going in the direction I put it. A quick search resulted on this page which had many interesting facts about earthworms:-

Dew worms can live for approximately six and a half years.

They do not have eyes but they do possess light- and touch-sensitive organs (receptor cells) to distinguish differences in light intensity and to feel vibrations in the ground.

 Earthworms are hermaphroditic meaning each worm has organs of both sexes.

 Earthworms respire through their skin, and therefore require humid conditions to prevent drying out.
