Do whales need water to drink?
Despite a few exceptions,
pinnipeds and cetaceans do not usually drink
. In most cases, water is supplied by the metabolism of prey proteins (metabolic water) and the oxidation of fat (drinking water). In cetaceans, these waters may be sufficient to maintain a water balance in the body.
Can whales survive without salt water?
Even though these marine mammals thrive in the ocean, whales cannot live in freshwater environments, at least not for long periods of time. In fact,
all known whale species live and thrive in saltwater environments rather than freshwater
, and there are several reasons for doing so.

.
Why can’t dolphins live in freshwater?

Do beached whales explode?
Whales can apparently hold in gasses, or the “death burp,” for long periods after they die,
sometimes resulting in massive and extremely messy explosions
.
Can a beached whale be saved?

some of these whales do survive
. If you spot a beached whale, call the local authorities immediately. Do not attempt to approach the whale on your own—you never know when that powerful tail will decide to thrash, or if they might carry diseases. Let the trained professionals lead the rescue.

. Breathing near the surface where whales sleep allows them to breathe more conscientiously, meaning each and every breath counts.
Why do whales become beached?
The beaching of a single, live animal is usually the result of
sickness or injury
