They are mammels but don't appear to have fur.
Do all mammels have fur or just most mammels?

Yes but they wax so it's hard to tell.

Yes! Dolphins, Whales & Porpoises do have hair. They don't have a coat of fur, at least they haven't done for millions of years. But although, it's not exactly a question which many people would be likely to ask, they do have a few hairs on their bodies. A large majority of people may say "well, obviously not!" But in all honesty, Cetaceans do have hair on their bodies.

All mammals have fur and feed their young on milk. However the cetacean hair is fine and sparse and also covered with a layer of a slime-like substance to cut down on drag in the water. Some older bull whales have a sort of visible "mustache".
All cetaceans are mammals, therefore all have hair.

Whales, porpoises, dolphins etc. belong to the order Cetacea of Class Mammalia. Cetaceans (sea dwelling mammals) have hair from birth and as their organs mature, they begin to lose hairs and in almost 1 month or so they are completely hairless. All mammals have growth of hair whether it is degenerative (falls with age) or increasing.

One of the things that defines mammals is hair or fur of some kind; in whales, dolphins etc. it's just a few hairs or bristles, which you don't really see.

No not all mammal's have hair or fur.
For example there is a breed of cat which has no fur (no i don't mean a cat frozen like the one in Austin Powers)
The naked mole rat (says it all really).
It depends on there habitat. Dolphins and Whales need to be sleek so there isn't so much friction, it lets them travel with ease underwater and this is also the same reason why athlete swimmers shave/wax there body hair.
Hope this helped :)

As mammals, they do have hair follicles, but do not necessarily have visible hair.
Some of the dolphins I worked with had a few visible hairs on their lower jaw, but they tended to disappear as they grew.
By the way... Dolphins are NOT covered with a layer of slime. They are very smooth and not at all slimy.

Actually they do have remnants of hairs sometimes, but it is a recessive trait.
Hair... may be greatly reduced in the Cetacea, where it is found as a few scattered bristles
about the lips or often present only in the young

Any critter that stays in the water all the time has no hair.
Some varmints like seals and walruses etc have thick fur to keep them warm when they emerge from the water.

no, they don't. they have completely lost it evolution. they once had it when there ancestors lived on land but it was lost when they went back into the water. they are tetra-pods, but they are mammals because of the double lining of the placenta. mammals are not defined by fur, but by other anatomical structures, in the reproductive system.

Yes Porpoises have mushtashes so that people don't confuse them with Dolphins
