Can dolphins only live in saltwater?
Most dolphins are marine and live in the ocean or brackish waters along coastlines.

Of the 40 + known dolphin species, most species are not known to live in freshwater environments, at least not for long periods of time. Dolphins that are not considered freshwater dolphins may visit or travel through freshwater environments, but they ultimately return to their saltwater habitat.
Do dolphins get thirsty?
The answer is: they do not drink water like land animals do, as they don’t risk dehydration from the sun. This goes for all the marine mammals like whales, dolphins, seals etc. The way they get water is through their food.

The large surface area of the gills helps them collect as much oxygen as possible. If they’re unable to do this, they can drown (although we know it’s technically more like suffocating).
