Dolphins are highly intelligent marine mammals and are part of the family of toothed whales that include orcas and pilot whales. They are found worldwide, mostly in the shallow seas of the continental shelves, and are carnivores, mostly eating fish and squid. Dolphin coloration varies, but they are generally gray in color with darker backs than the rest of their bodies. They are beautiful creatures.
However, to answer your question, as Dolphins are Marine Mammals they give birth to live offspring rather than eggs.
Random but interesting fact -
As with all animals, Dolphins engage in a lot of foreplay before sex, winning over the female they wish to reproduce with. However, they are also known to have sex for reasons other than reproduction, even engaging in homosexual behaviour or with dolphins from another species, which is unheard-of in the animal kingdom.
