Green bromeliad frog
This frog lives in bromeliad plants.  Bromeliads are plants that can live on the ground or high up on other plants.  Rainwater collects in the leaves of the bromeliads.  The frogs lay their eggs in this water.  The first tadpoles to hatch eat the other eggs.  Scientists think the tadpoles may also eat each other.  Osteopilus brunneus tadpoles do eat green bromeliad frog tadpoles if they are in the same plant.  But Osteopilus brunneus lays its eggs in larger bromeliad plants, and the green bromeliad frog lays its eggs in smaller ones.  Scientists think green bromeliad frogs do this so that the Osteopilus brunneus tadpoles will not eat their young.
