What critical prerequisite must environmental triggers meet to initiate the hatching of *Triops* cysts?

Answer

Specific temperature and moisture levels

The hatching process for *Triops* cysts is not random; it is governed by highly tuned biological sensors designed to detect precise external cues to ensure survival. The eggs require a specific combination of both temperature and moisture to trigger the transition from diapause back into active development. If the initial rainfall event is too brief or the temperature is inadequate, the eggs will conserve their energy stores and refuse to hatch, waiting instead for the next, more substantial deluge. This selectivity demonstrates a risk-averse programming that prioritizes waiting for conditions guaranteeing pool permanence over hatching prematurely into a doomed environment.
