Abstract: The interplay between cannibalism and life-history traits is still poorly understood. This study investigates the relationships between sex, snout–vent length and the amount of ingested conspecific eggs in three populations of sword-tailed newts, Cynops ensicauda popei. The mean number of ingested eggs found per individual was 0.13, 0.22 and 0.31 depending on the population, and females were more cannibalistic than males. Mean body size was negatively related to the mass of ingested conspecific eggs, and positively related to the total number of prey items found. Taken together, this study suggests that the amount of cannibalism is primarily influenced by prey availability and body size.
