Haplochromine Cichlid Teeth (image) University of Leicester Share Print E-Mail 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.
