A precursor of the information on the Tatra mountains' fauna was Staszic, who having referred to his own observations, made mention to fishes in the 'Morskie Oko' lake . The information was later also confirmed by Zawadzki, Jarocki and Plater. A beginning of the modern searches on the Tatra mountains' waters we owe to professor Nowicki. He had not only recognized fishes, amphibians, the phylum Mollusca and insects inhabiting the waters, but also described new species for science. The disciples and followers of Nowicki continued on his searches. Dziedzielewicz took up research works over fauna of neuropterous insects in the Tatra mountains, including also the species living in the Tatra mountains' waters. Lomnicki and Rybinski did research works on the cockchafers' distribution. In 1890 Bobek, referring to Nowicki's searchings, started to investigate Diptera of the Tatra mountains. Then Kotula and Bakowski began to describe snails and molluscs. The most eminent disciple of Nowicki was Wierzejski - an author of many articles concerning fauna of the Tatra mountains' lakes. He concentrated on exploring planktonic crustaceans and also made mention to other groups of invertebrates: hydras, Tricladida, nematodes, rotifers, leeches, Oligochaeta, water insects and molluscs. He also mentioned fishes and amphibians. Jointly, referring to his own searches, he recognized 80 species of the Tatra mountains' lakes. In the history of faunistical researches on the Tatra mountains he is said to be a discoverer of the relict species of crustacean Branchinecta paludosa. Besides the followers of Nowicki, Stobiecki described heteropters, and Rozwadowski and Niezabitowski studied on fishes. The disciples of Wierzejski were Litynski and Minkiewicz, who explored crustacean zooplankton. Apart from fundamental for the Tatra mountains' monograph concerning cladocerans (Cladocera), Litynski explained the reason why the distribution of Branchinecta paludosa is confined to Dual Caterpillar Ponds. On the other hand, having presented a description of fauna in 38 lakes of the Northern Tatra mountains and in 44 lakes of the Southern Tatra mountains, Minkiewicz pointed out their 399 species.
