Mammals have a horizontal tail.
Fishes have a vertical fin.
We can hear the bull shark is very dangerous because of attacks near La Réunion island.
However, tens of them are living at 600 feet from the famous beach of Playa Del Carmen in Mexico. And there are no attacks.
The kakihona sushi (sushi wrapped in persimmon leaves) are really the best!
To eat them, you have to go to Nara!
