All dolphins are marine mammals and as such are all vertebrates.
Since this has been asked in the Aquatic Mammals category instead of fish, I assume you are not referring to the Dolphinfish, or mahi-mahi, Coryphaena hippurus (which incidentally are also vertebrates)
They are all veretebrates.
The awnser to this is: earthworms are cold blooded. They are also inveretebrates which means they have no backbone to support them they only swiggle around.
snakes have backbones so they are considered vertebres, but an interesting fact about them is that they have a pelvic bone which really serves no purpose because they don't have any legs, well not since the devil pulled his stunt with Adam and eve.
only one species of dolphins at this time that are going extinct are the pink river dolpinsHector's dolphins (New Zealand dolphins) are also in danger of becoming extinct. The endangered river dolphins are Amazon River dolphins, Ganges River dolphins, Chinese White dolphins, Indus River dolphins, and La Plata River dolphins.
Dolphins are vertebrates.
