ABSTRACT
Laboratory-reared shore crabs show circadian rhythmicity which is transformed to approximate tidal rhythmicity after a period of chilling to 4° C.
Periodogram analysis of the results characterizes the periodicity of the two types of rhythm, which suggest that the ability to show a rhythm of tidal periodicity is an inherited feature of shore-crab physiology.
