Ranoidea

The **Ranoidea** are a superfamily of frogs in the order Anura. These frogs have a fused pectoral girdle bone in their chests, no ribs, and the males hold on to the female with an axillary grip during mating. The tadpoles have a single spiracle on the left side and complex mouthparts. Some species do not have tadpoles, and small frogs grow straight from eggs. Scientists disagree about exactly which frogs should be placed in which family and on exactly where Ranoidea belongs among groups of amphibians.  Amphibian scientists often change their minds about exactly which frogs are related to each other and how closely, usually when someone finds new information (Glaw,Vences, 2001).

This superfamily contains seventeen different families, each containing at least 2 species (some contain over 300&nbsp;different species).

Cacosternine frogs are small and slender and live on the ground or in and out of water. Pyxicephaline frogs are large bullfrog-like frogs with thick bodies and fanglike bones on their lower jaws, used to smash their prey.

### Petropedetidae 
The family of Petropedetidae (African Water Frogs and Goliath Frog) has two genera with a total of 18&nbsp;different species. They live in Sub-Saharan Africa. This family contains the world's largest living frog, the *Conraua goliath.*

### Ptychadenidae 
The family of Ptychadenidae (Grassland Frogs) has 3&nbsp;genera with a total of 53&nbsp;different species. They live in sub-Saharan Africa. They live in grasslands and savannas. They have slender bodies with long arms and legs.

### Ceratobatrachidae 
The family of Ceratobatrachidae (Triangle Frogs) has 5&nbsp;genera with a total of 84&nbsp;different species. They live in Malaysia, the Philippines, Borneo, New Guinea, and the Solomon Islands. Most have very angular bodies and are small to medium-sized. They live in the forests.

### Brevicipitidae 
The family of Brevicipitidae (Rain frogs) has 5&nbsp;genera with 31&nbsp;total species. They live in the southeast corner of Africa. They are typically small with round shaped bodies, which become even more round when they are disturbed because they inflate themselves.
