Physiology of hemolymph, gut fluid, and hepatopancrease of the land crab Gecarcinus lateralis (fréminville) in various neuroendocrine states
1. Speciemens of Gecarcinus lateralis were studied in varied neuroendocrine states: i.e. crabs with eyestalks in intermolt and at echysis, destalked crabs at ecdysis and destalked crabs, thoracic ganglionic mass (TGM)-implaneted, at ecdysis.
2. Protein in hemolymph is significantly decreased in destalked crabs at ecdysis. Implanted destalked crabs had a higher protein content than non-implanted.
3. Osmorlarity of hemolymph is lower in all animals at ecdysis than in intermolt. Distribution of fluids is abnormal in destalked crabs; it is partialy corrected implanting a TGM.
4. Hepatopancreatic water and lipid content are comparable in all crabs at ecdysis.
5. The significance of these results to the biology of the crab is discussed.
