Ana tsammanin yawan sinadarin phosphate, wanda ya samo asali daga zaizayar ƙasa, shine babban abin da ke takaita bambancin dabbobin ruwa. Babu kifi. An rubuta ƙwayoyin da ba su da ƙashi waɗanda suka fito daga ƙungiyoyi huɗu na taxonomic (Annelida, Gastropoda, Crustacea da Insecta). Arzikin taxonomic ya kasance mafi girma (taxa 15) a watan Afrilu (lokacin damina) kuma ya ragu zuwa taxa 11 a watan Agusta (lokacin busasshe). Gabashin tafkin yana da nau'ikan da suka fi na yamma yawa, wataƙila saboda ƙarancin gishirin da ake samu akai-akai. Ƙwayoyin crustaceans su ne nau'ikan da suka fi yaɗuwa. Naman ruwa da aka rubuta a Tafkin Tsimanampetsotsa kamar haka: ^[2]
