A Dolphin as 2 eyes. One of each side of it's head. It can see both in and out of the water. Dolphins have very sensitive skin. It is made up entirely of live cells, unlike human skin that is protected against injury on the surface by dead cells.
Dolphins bruise easily.
When bruised, it appears as if the dolphins have a wound or illness. Researchers handling or releasing dolphins must take extra care not to bruise the animal by bumping up against anything. Dolphins love to rub against each other and the hands of humans but are careful not to bruise themselves. I hope that you liked it.
