Many dolphins swam fast - level 2
Many dolphins were filmed off a Japanese coast. They were fleeing from killer whales.
The dolphins had to be faster than the killer whales. Otherwise they would be killed and eaten by them.
Orcas eat dolphins and they live in groups just like the dolphins. They can be seen all the way from the Arctic to tropical waters.
Interesting words: off (near), flee (run from), killer whale (big black and white sea animal), orca (another name for a killer whale).
You can read the original story and watch the video in the Level 3 section.
