The Y-organs of the xanthid crab Menippe mercenaria secrete the ecdysteroids, 3dehydroecdysone (3DE) and lesser amounts of 3-dehydro (or 2-dehydro)-25-deoxyecdysone (3D25dE) in vitro. These ecdysteroids were identified by elution-time comparisons with authentic standards, mass spectrography, and, fo
## Abstract Specimens of the stone crab, __Menippe mercenaria__, survived severe hypoxia (PO~2~ < 8mm Hg) for at least 12 hr at 28β30Β°C. During the time course of 12 hr of hypoxia, hemolymph Lβlactate levels rose to 30β50 ΞΌmoles/g wet wt. There was a slight elevation of Lβalanine levels, whereas su
