This ray hunts in the sand and moves by waving its wings.
It has a dart along its tail, which can be dangerous in case of bites on the man, but the blue spotted stingray don't attack, just be careful and don't hurt it.
This ray breathes through the top of the head and exhales from the bottom, allowing it to not suck sand.
Some sharks can stay motionless on the sand (white tips reef sharks, nurse sharks, etc.).
These sharks don't have to swim to bring oxygen to their gills like other sharks (grey, hammerheads tc.)
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!
