Rana esculenta (Ranidae) - Beuteerwerb
The film shows the prey-catching behaviour of the edible frog at a small garden pond and at a gravelpit. The catching of creeping and (under experimental conditions) hanging earthworms, of flies sitting on the surface of the water and of egglaying dragonflies (Sympetrum spec.) in tandem position are visible.
