Killer Whales vs Witty Otter

I saw this a while ago and downloaded it and saved it. I always love animal videos and who says that a animal does not feel the loss of a young one.
 
Its sad too see, im an animal lover, and i have fish, and with me being a natural born worrier, im always checking my fish pond to see that there ok , and that no birds have tried to eat my fish :cry:
