Brain size predicts foraging and escaping abilities in the paddy frogs

Abstract

The three experiments revealed that successful individuals with spatial learning and escaping had relatively larger brains than unsuccessful ones in three species of the paddy frogs. We first provided experimental evidence for whole-brain size as a predictor of cognitive abilities in the paddy frogs. Our findings support the claim that brain size can reflect an animal's spatial learning and escaping abilities and enhance our understanding of larger brains evolved with better cognitive abilities in frogs.
