Frogs typically lay their eggs in water. The eggs hatch into aquatic larvae called tadpolesthat have tails and internal gills.
They have highly specialized rasping mouth parts suitable for herbivorous, omnivorous orplanktivorous diets. The life cycle is completed when they metamorphose into adults.
A few species deposit eggs on land or bypass the tadpole stage. Adult frogs generally have a carnivorous diet consisting of small invertebrates, but omnivorous species exist and a few feed on fruit. Frogs are extremely efficient at converting what they eat into body mass. They are an important food source for predators and part of the food web dynamics of many of the world'secosystems. The skin is semi-permeable, making them susceptible to dehydration, so they either live in moist places or have special adaptations to deal with dry habitats. Frogs produce a wide range of vocalizations, particularly in their breeding season, and exhibit many different kinds of complexbehaviours to attract mates, to fend off predators and to generally survive.
