Near the surface, they are mammals meaning they need air to breath just as much as they need water
well just think about it, dolphins are mammals, therefore, they need oxygen to breathe. dolphins can get some oxygen out of the water like whales, but there is absolutely no oxygen on the bottom, and it would take a very long time for the dolphin to get to the surface. middle.

Piranhas live in freshwater rivers not in oceans at any depth.
Because it is.
Nemo lives in the coral reef which is near the surface of the ocean. So the drop off is the part to the ocean floor. Remember the 3 parts of the ocean: The surface, the mid-section, and the ocean floor!
Surface water salinity ranges from 32 to 37 parts per 1000
The range for annual mean ocean-surface salinities typically falls between 33 to 37 parts per thousand (ppt). This range can vary based on factors such as location, climate, and ocean currents.

nORTHING
One thing that we can do to help all the dolphins, is to stop pollution to the ocean. If a plastic water bottle is in the water, a dolphin could mistaken it for a fish. We could also use nets (to catch fish) safe for dolphins, by having little gates at different parts of the nets, and 3-4 divers could be there to make sure no dolphins get caught, and if any do, to help them through the gates.
