They are divided into 16 families, with 9 occurring in North America. Frogs like to be in or near water. Frogs are usually found near shores of lakes, ponds, or streams. In the summer they wander farther from the water in search of food. Frogs can live equally well in water or on land.
Frogs feed using their long tongue.
Their hunting style is to sit and wait for their food to come to them. The frog flicks the tongue out at high speed and snaps up whole invertebrates. The frog has numerous, cone teeth around the edge of its jaw and two patches of vomerine teeth on the roof of its mouth to prevent the prey from escaping. The food is then digested through a simple digestive system. Frogs absorb water through their skin.
