Good point.. and I guess the answer all depends on perspective.
Like.. if you're the male fish pointing & poking fun (though I'm not sure how that's done with no arms), I guess you'd be calling said female fish (that likes fishsticks in her mouth) a human - albeit as a taunt at how her actions are unlike those of the other female fish, but that, with all their fishly wisdom, they're aware humans carry out such activities on one another.
If you were a human, poking fun at said fishstick-sucking female fish, I guess it'd depend on your general perspective as well.. if it were me, I guess I'd call her a Hoochie-Mumma Fish. ref:

If you were another female fish, you may even be tempted, perhaps, to call her a Pioneer... discovering new uses for the fish stick.
There.. never let it be said I don't give an important topic correct & thorough attention.
