うみのきょじん　マンタ

Swimming next to a manta ray is a great privilege, because she is one of the giants of the ocean, the manta rays can measure eight meters and weigh 1400 kilograms, recently we learned that they are family of sharks.

We know very little about the manta ray, they are a mystery, because they can't live in an aquarium. The greatest danger to the manta ray is the fishing harpoon. But the manta rays are still a really mistery.
