Ocular reflecting pigments of some malacostraca

Journal of Experimental Marine Biology and Ecology, 1971
Abstract Eyes of nineteen malacostracan crustaceans (sixteen from coastal, three from deep water) have been examined for purines and pteridines, with a view to determining their role as reflecting pigments. White shrimp, Penaeus setiferus , received most attention; other animals examined were one isopod, one stomatopod, eight penaeids, six ...

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.
