Haplochromine Cichlid Teeth (image) University of Leicester Caption Haplochromine cichlid fishes that eat algae in different ways have very different tooth wear. The teeth on the top row are from fish that scrape algae from plants; those in the middle row are the same species, but scrape algae from rocks. The roughest teeth, those on the bottom row, are from a species that specializes in rock scraping. Credit Mark Purnell, University of Leicester Usage Restrictions Use only with credit.
