A method of direct recognition of cells in zoos and wildlife. How was it differentiated? Why was it different? Plss help mee

i got you i did it ya know what it is just needing to fill this in for a quick task!

fumikage isn't really a bird, and tsuyu does have teeth. tsuyu has a transformation quirk which still allows her to be partially human. otherwise we'd have a large frog running around. fumikage has teeth because again, he isn't a bird. his head was a quirk mixture if i'm correct.
