Postembryonic development and differentiation of the midgut in the freshwater shrimp Neocaridina davidi (Crustacea, Malacostraca, Decapoda) larvae

Journal of morphology, 2020
Neocaridina davidi is a freshwater shrimp that originates from Taiwan and is commonly bred all over the word. Like all decapods, which develop indirectly, this species has pelagic larvae that may differ entirely in their morphology and habits from adult ...

Ultrastructure of maxillary gland ofAntrobathynella stammeri (Syncarida, Malacostraca)

Journal of Morphology, 1996
The 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, 1992
An 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.

Evolution of Optical Design in the Malacostraca (Crustacea)

2002
How much can compound eye structure and optical design tell us about the phylogenetic relationships and evolution of the carriers of the compound eyes, in our case the crustaceans? To answer this question, it is necessary to distinguish between compound eye morphology and the cellular composition of the ommatidia on the one hand, and eye physiology and

Notes on Paleozoic Malacostraca of USSR. Pygocephalomorpha

International Geology Review, 1967
The classification of higher crustacea is reviewed and the family Tealliocaridae is considered to be a synonym of Pygocephalidae of the order PygocephalOmorpha. Hitherto only two representatives of Paleozoic higher crustacea have been known from the USSR.
