Frogs respond to predation before they hatch

Frogs respond to predation before they hatch

Niklas Fuchs and M.-O. Rödel, in their 2025 paper, provide the first description of juvenile Pristimantis latidiscus. They document an egg-burying behaviour, interpreted as a simple form of parental care. The frogs bury their eggs—presumably as a protective strategy. In experimental manipulations, eggs that were handled every two days (to simulate disturbance or predation) hatched significantly earlier than undisturbed eggs, demonstrating phenotypic plasticity in hatching time that may reduce predation risk
