Lifespan extension in a semelparous chordate occurs via developmental growth arrest just prior to meiotic entry.

Growth arrest (GA) discovered by culturing animals in crowded conditions, but can also be striggered by reduction of food intake before D4. After that, starvation reduces the number of gametes produced instead of inducing GA. In GA, cell cycle stops in both the somatic and germ lines. GA can also be induced by the TOR inhibitor CCI-779. Animals in GA can survice up to ~18 days at 15°C.
