      The Lake Magadi tilapia, Oreochromis alcalicus grahami, is remarkable among teleosts in that it flourishes under extremely well-buffered alkaline water conditions (pH10, CCO· 180mmol l21) at temperatures of 30–40°C (Wood ...

      Randall, DJ; Wood CM; Perry, SF; Bergman, H; Maloiy, GMO; Mommsen, TP; Wright, PA (Nature Publishing GroupDepartment of Veterinary Anatomy and Physiology, University of Nairobi, 1989-01)
      Ammonia is toxic to all vertebrates. It can be converted to the less toxic urea, but this is a metabolically expensive process found only in terrestrial vertebrates that cannot readily excrete ammonia and marine fish that ...
