1. When not oxygenated, hemolymph quickly loses its color and appears grey.

2. [Variations in the lipids of the ovary, the hepatopancreas, and the hemolymph of the female crab Pachygrapsus marmoratus Fabricius (Decapoda, Brachyoura) during the intermolt cycle].

3. Between these the terminal branches of the nervus glandulae cerebralis are found, and a system of lacunae which communicate with the surrounding hemolymph.

4. At an adaptation temperature of 5°C aestivating edible snails, which have closed the aperture of their shells with a skin slime, exhibit a lower content of Fe, Zn, and Pb in the hemolymph and other organs than do hungry edible snails at AT=20°C.

5. A comparison of the 2 weeks active snails against 2 weeks Aestivated animals, showed that 23 metabolites (log FC > 16, p < 0.0001) were found to be elevated in the 2 weeks active hemolymph samples, while 1 metabolite was decreased, as compared with the 2 week Aestivated samples .
