Females have an eardrum (tympanum) the same size as their eye. Males eardrums are larger.
Male frog: "Hey baby baby baby! I gottem many bugs!"A female bullfrog may lay up to 25,000 small eggs that are held together at the surface of the water.
Female frog: "hey baby, I'll hop over to your pad tonight!"
They tend to live in vegetation along the edge of large, slow moving, bodies of freshwater.
Where they occur naturally, bullfrogs help keep down the mosquito and insect population. But in some places where they have been introduced, they eat so much that they can destroy local populations of native frog species!
Their populations can bloom out of control because they don't really have natural predators (infact, they can give off some nasty toxic secretions from their poison glands (called paratoid glands) that can poison a dog if it tries to eat one!).
