The larvae settle on the sediment and the entire larval development takes 8–10 days and there is synchrony in the development of larvae inside the egg mass as well as synchrony within all the jelly masses collected within a particular area at a particular time. Egg masses are present throughout the entire year. While Pulicat Lake and Ennore Creek are linked, water flow only occurs during floods with the last observed flow in 2015.
