Florence is a nurse shark who lives in an aquarium in Birmingham, UK. She's a strict vegetarian. Even when her caretakers wrap fish in lettuce, she turns away from it. Instead, she competes with other herbivores for plants:

Florence’s mouth is filled with razor-sharp, serrated teeth designed for demolishing fish and crustaceans.

Instead she uses them for pulping broccoli and cabbage and any other greens she can steal from fellow ocean tank resident Molokai the green turtle.

I suspect that she simply hasn't encountered bacon yet.
