The first animal was taught about to me in the first class of my first Science College I studied. I was not able to get a clear idea about it in the lecture. Earlier I had been taught only about fish, frog and rabbit in Pre-University Course. This animal was a different one - it was neither like a worm or a fish! It is the Amphioxus (Bronchiostoma lanceolatum, Lancelet). It is a primitive animal from which vertebrate animals developed by evolution. It is fish-like and of 2 inches length. It has a transparent body without fins. But has no eyes.
