Deep Blue

I watched the movie which is named “Deep Blue” in last week. It is a documentary movie by BBC and described the world of ocean. This movie has much information of marine creatures, and we can know about the life of the sea. For example, the way of living about deep-sea creatures, and I was very surprised at this. Anyway, we can learn about the sea from this movie. Also, I became to be interested in a killer whale. Do you know it? It is one of the whales but similar to a dolphin. The length of this animal is about 9m, and it’s a predatory animal. Killer whales like to eat a seal, and they kick it when they hunt them. That scene is very cruelly, but I can know the existing of food chain clearly. Therefore, I recommend you to research about them.
