Mechanisms of heavy metal cation homeostasis in marine invertebrates
On the Structure of the Antennular Attachment Organ of the Cypris Larva of Balanus balanoides (L.)
The presence of chemoreceptors on the attachment organ of the cypris larva indicates that a chemosensory mechanism could operate during the gregarious behaviour of settling cyprids.
Functional cytology of the hepatopancreas of Penaeus semisulcatus (Crustacea: Decapoda) during the moult cycle
In the shrimp Penaeus semisulcatus, the digestive gland functions as the main site for the digestion, absorption and storage of nutrients and metals during the feeding stages of intermoult and for…
Studies on the digestive cycle of the shore crab Carcinus maenas (L.) with special reference to the b cells in the hepatopancreas
Aspects of the digestive cycle of Carcinus maenas have been studied by transmission and scanning electron microscopy, X-ray microanalysis and light microscopy. Movements of ingested material have…

R-cells and the digestive cycle in Penaeus semisulcatus (Crustacea: Decapoda)
Observations on the nature of intracellular storage and waste products could be used to assess the dietary requirements of artificially reared shrimp and a scheme is proposed which accounts for the main processes of digestion.

The activity of proteases and amylases has been demonstrated in the secretion produced by the gland but the source of these enzymes is attributed to different cells and various modes of secretion are proposed.
Cadmium metabolism in the clam Ruditapes decussata: the role of metallothioneins
B-cells and digestion in the hepatopancreas of penaeus semisulcatus (Crustacea: Decapoda)
The B-cells most closely resemble those described and illustrated in this paper for the period 24 h after feeding.
Accumulation of copper within the “Hepatopancreatic” caeca of Corophium volutator (Crustacea: Amphipoda)
Various tests on the granules in frozen section indicate that they are relatively insoluble in a wide range of reagents and that the copper is probably complexed with organic matter.
