Because they're from another planet. If Michelangelo suddenly zapped out of the cartoon and into our world, his species would still be "Sentient Cartoon Turtle" or whatever the analogue of what was written on W&S's would be... his species would still be Mutant Turtle.

The "coming from a comic book" thing would be an origin, not a species.
