Abstract

The cyclicity of moon acts as a synchronizing cue to the sea life through tides. It exerts selective pressure such as water pressure, air exposure etc. causing wide affects ranging from timing of reproduction to migration. Although it is established that intertidal cyclicityis pervasive, the extents of its interplay with daily changes in light and dark cycles is not clearly understood. Chronobiological studies on marine invertebrate life are important to unveil the modulation of the interaction of daily and tidal rhythms with the course of evolution. Further, melatonin, ‘the hormone of darkness’ is a phylogenetically conserved molecule known for sleep-regulation in vertebrates. The characterization of melatonin in invertebrates has reiterated recognition of putative role of melatonin as an antioxidative protectant involved in the detoxification of destructive radicals, besides a transducer of photoperiodic information. In recent decade, molecular investigations of invertebrate clocks have suggested complex biological clocks-controlled by multiple clock output pathways with plasticity daily downstream events.
