And now the answer, courtesy of the Vancouver aquarium:

What's the difference between a dolphin and a porpoise?
There are slight physical differences between dolphins and
porpoises:
Porpoise teeth are shaped like spades and each tooth has a long,
sharp upper edge.
Dolphin teeth are shaped like cones and are pointed.
Porpoises tend to be smaller than dolphins and usually do not
have pronounced beaks.
So if it's a larger pointy-toothed beaked aquatic mammal, it's a
dolphin. Otherwise think porpoise. No wonder no one can remember
the difference between them.
