During the developmental process of the Tyrant-Crowned Puffer, distinct positive allometric growth occurs, with the skull gradually shifting from a light and agile juvenile form to a heavier one, and the legs becoming more robust, transforming from nimble suitability for rapid pursuit to sturdy power for explosive bursts. The ecological niche also changes with age: juveniles are gregarious, excelling at group encirclement and hunting of prey with faster running speeds. In adulthood, they adopt a monogamous system, collaboratively pursuing and subduing large prey. The elderly typically live solitarily, subduing prey with their own strength.
