Bullfrog Dad Protects His Tadpoles

The African bullfrog (Pyxicephalus adspersus) is the biggest frog in Africa and very aggressive. But in spite of that, it s a devoted father. Bullfrogs spawn in little pools around the margins of larger ponds and after mating is over one male stays to keep watch over the newly hatched tadpoles. If the pool begins to dry up the dutiful dad digs a channel to a new water source.
