Living small in a big city: Urban Túngara frog tadpoles develop faster but end up being tinier

Have you ever wondered how city life affects animals like frogs? A new study reveals that urban Túngara frog tadpoles develop faster—but end up being smaller—than tadpoles from forests, probably resulting in smaller adults. This might be an adaptation to warmer urban puddles with fewer predators or to constantly changing environmental conditions in the city.
