Scientists have now identified a woven microstructure that enables parrotfish to chomp on coral tirelessly.
Why we should not eat parrot fish?
Parrotfish are herbivores that eat plant life by chewing hard corals and digesting the encrusting algae and zooxanthellae (symbiotic algae that lives in coral polyps.) … In this way, the parrotfish can contribute enormous amount of sediment to the sea bottom and beaches – over one ton of sand per year!
What is the life span of a parrot fish?

Is parrot fish high in mercury?
The fish species with the highest-ranked selenium concentrations (ranked 1–4) were goatfish, cod (dried), parrotfish, and “wenchman.” Incidentally, some of these species were also ranked highest in mercury concentration. The arsenic concentration of the samples in this study ranged from 0.1 to 8.1 μg/g.
