It is endemic to relatively deep waters in Lake Tanganyika in the countries of Burundi, the Democratic Republic of the Congo, Tanzania, and Zambia.[1] It is widespread in the lake, but occurs in low densities.[1] It has been recorded as deep as {{convert|200|m|ft|abbr=on}},[2] even in waters virtually devoid of oxygen.[3] This species reaches up to {{convert|15|cm|in|abbr=on}} in length[4] and has an unusual protractile mouth.[1] It feeds on zooplankton[1] and will shift sand, similar to the distantly related Geophagus eartheaters of South America.[2] Like many other Tanganyika cichlids, it is a mouthbrooder[4] and occasionally seen in the aquarium trade.[2] References1. ^1 2 3 4 {{cite iucn | author = Bigirimana, C. | year = 2006 | title = Gnathochromis permaxillaris | journal= The IUCN Red List of Threatened Species | volume = 2006 | page = e.T60493A12364587 | url = http://dx.doi.org/10.2305/IUCN.UK.2006.RLTS.T60493A12364587.en | accessdate = 2 February 2019}} {{Taxonbar|from=Q3278611}}{{Cichlidae-stub}}2. ^1 2 SeriouslyFish: Gnathochromis permaxillaris.
