Influence of ecdysterone on molting in Palaemonetes
General and Comparative Endocrinology, 1972Abstract Since many female decapod crustaceans are known to delay molting until after release of their larvae or young, such ovigerous female shrimp may have a high titer of molt-inhibiting substance. At that time, comparison can be made between ovigerous females and mature males in terms of their response to injections of a molting hormone ...

The arterial system of Palaemonetes
Journal of Morphology, 1930AbstractColor changes in Palaemonetes had been found to be inhibited in the whole abdomen by occluding the dorsal abdominal artery. Inasmuch as these chromatic responses are brought about by means of circulating hormones, it should be possible, in view of early anatomical findings, for specific substances to reach the abdomen by way of the ventral ...

Abstract 1. 1. Determined lethal limits (96-hr LD 50 , values) for Palaemonetes pugio adults are 0.5 and 44‰; for larvae (first zoeae), 16 and 46‰ 2. 2. The concentration of blood sodium remains relatively constant over the salinity range 1–40‰ 3. 3. In relation to other species of Palaemonetes , it is suggested that P.

Rhabdom changes in the shrimp, Palaemonetes
Cell and Tissue Research, 1976The fine structure of the principal compound eye of the shrimp, Palaemonetes, was studied under conditions of light and dark adaptation. Ommatidium the situation in other decapod crustaceans. Light and dark adapted eyes differ in that the rhabdom changes its shape; morphological evidence suggests a possible sequence of events involving production ...

AbstractThe pigmentary system of Palaemonetes vulgaris contains four pigments. These are red, yellow, blue, and white. With the exception of the blue all are found exclusively within chromatophores and are capable of becoming either dispersed into chromatophore branches or concentrated into chromatophore centers.
