    • Abstract:
      In this study, we investigated effects of 24 weeks of food deprivation on covering behavior ofGlyptocidaris crenularisandStrongylocentrotus intermedius. NeitherG. crenularisnorS. intermediussignificantly reduced covering behavior during both short- and long-term food deprivation. However,G. crenularisandS. intermediushad significantly different behavioral patterns over the 24 weeks. Covering behavior ofG. crenularisgreatly increased from the first to the second week, with decreasing reaction time and increasing covering ability, while the covering behavior ofS. intermediusgenerally remained unchanged during the experiment of 24 weeks. As prolonged food deprivation does not significantly affect covering behavior ofG. crenularisandS. intermedius, the present study highlights the innate nature and biological significance of covering behavior in sea urchins, providing new insights into its behavioral mechanism.
