The whale shark is the largest fish in the world!
Some whales are larger, but they are mammals, not fish!
Mammals have a horizontal tail.
Fishes have a vertical fin.
Turtles are in economy mode when they are sleeping. If they are woken during night, they may not have enough air to return to surface.
So, please be careful during night dives!
