About the species

Petrotilapia tridentiger is the type species of Petrotilapia, a genus of robust, highly specialised algae-scraping mbuna that dominate the wave-washed rocky surf zone of Lake Malawi. Its name — Latin for "three-tooth-bearer" — describes the genus's diagnostic tricuspid teeth, packed in dense rows and built to comb algal turf off rock under the heavy surge that keeps subtler grazers away. Males of the genus are among the most muscular and pugnaciously territorial of the lake's mbuna.
