 Pelagic zooplanktonic species include two cladocerans ("Diaphanosoma excisum" and "Bosmina longirostris"), three copepods ("Tropodiaptomus cunningtoni", "Thermocyclops neglectus" and "Mesocyclops aequatorialis"), and several ostracods (including both described and undescribed species).Lake Malawi is famous for the huge swarms of tiny, harmless lake flies, "Chaoborus edulis".These swarms, typically appearing far out over water, can be mistaken for plumes of smoke and were also noticed by David Livingstone when he visited the lake.
