Survey and Distribution of Crustacea Malacostraca in Poland
Crustaceana, 1993AbstractThe paper presents a survey of Polish malacostracan fauna. In two tables the distribution of freshwater and Baltic species is presented according to the regionalization of the country used in "Catalogus Faunae Poloniae". Figures present some interesting distributions of freshwater malacostracan taxa.

Freshwater origin of Bathynellacea (Malacostraca)
Crustaceana, 2014There are two opposing hypotheses on the origin of Bathynellacea, a marine and a freshwater one. According to the marine hypothesis, Bathynellacea invaded continental groundwater from the sea via the interstitial of marine beaches (“two-step model”), whereas according to the freshwater hypothesis the groundwater was reached from the sea via fresh ...

General Characteristics of Malacostraca
2017Malacostracans are among one of the most species-rich classes in nature. The crustaceans in this class differ widely in size—from a few millimetres to almost one metre in length. Because of their complex morphological and anatomical structure, they are often referred to as higher crustaceans.

Ultrastructure of maxillary gland ofAntrobathynella stammeri (Syncarida, Malacostraca)
Journal of Morphology, 1996The maxillary gland of the highly adapted stygobiont species, Antrobathynella stammeri (Bathynellacea, Syncarida), consists of an end sac, an excretory tubule, and a terminal duct. No valve was found. The excretory tubule forms a loop extending back into the fourth thoracic segment. The end sac is composed of five typical podocytes.

Origin of Antarctic Isopoda (Crustacea, Malacostraca)
Marine Biology, 1992An analysis of the horizontal and the vertical zonation of the Antarctic Isopoda, combined with knowledge of the geological history of Antarctica and isopod phylogeny, revealed that the isopod family Serolidae and subfamily Arcturinae are likely to have evolved from ancestors that inhabited a cold-temperate Gondwanian province.
