When we swim, we flap our legs up and down. I thought all these days that this was the only way possible for me. However, I learnt that this is the way all mammals swim - flapping legs up and down. Even Dolphins and Whales flap their tail up and down. This is in contrast with what Fishes do - they swing their tails from side to side. So, I learnt that if we find any living being moving like is snake in the water, it has got to be a fish, maybe Shark. Otherwise, it is a mammal, maybe Dolphin or Whale.
