Do killer whales interbreed?

Why are most hybrid animals considered evolutionary dead ends?
One of the main obstacles is that, even if members of different species might mate, when the two species are too distant genetically or carry different numbers of chromosomes, the offspring are usually inviable or infertile (like zorses and mules), and are therefore evolutionary dead ends.
