You learn something everyday.

And seriously dolphins and whales can both have offspring!?

Since dolphins are generally much smaller than whales, I would say copulation between a dolphin and a whale to be as logistically impossible as cross breeding between tigers and house cats.

I think the underlying grain of truth might be similar species of dolphins might mate amongst themselves, or similar species of whales might mate, but not between dalphins and whales.
