At what temperature does the yabby's system cease feeding and metabolism during slowdown?
Answer
Below 16°C
The yabby exhibits extreme metabolic plasticity, allowing its internal economy to dramatically scale down in response to unfavorable environmental cues, particularly cold temperatures. While the ideal range for active growth is between 20°C and 25°C, and survival is possible up to 35°C or down to 1°C, there is a specific lower thermal threshold linked to fundamental life processes. When water temperatures drop below 16°C, the organism triggers a shutdown of non-essential functions. This involves the cessation of active feeding behavior and a substantial slowing of overall metabolic rate, transitioning the creature into a low-energy maintenance mode designed to conserve resources until warmer, more productive temperatures return.
