## Abstract Melatonin was injected into intact and eyestalkβablated fiddler crabs (__Uca pugilator__), and its effects on hemolymph glucose and lactate levels were studied. In intact crabs, glucose and lactate levels cycled simultaneously, with peaks occurring during early and late photophase. Mela
Persistent 24-hour rhythms of migration of retinal pigments in the compound eye have been reported for several crustaceans. Review of the literature disclosed that any one or any combination of the three pigments, distal, proximal, and reflecting, may exhibit a 24-hour rhythmicity (Brown, '44 ; Klei
