Pipidae - tongueless frogs

African Clawed FrogThere are 32 species of aquatic frogs in this family. They are found in South America and Sub-Saharan Africa.

They have webbed feet, no tongue, and claws on one or more of their toes! The frogs in this family rarely come out of the water! They even have a special adaptation in their ears that allow them to hear under water.

Just like fish, the frogs in this family have a lateral line on the sides of their body that helps them sense motion in the water!

The African clawed frog has been introduced in North America. Populations of African clawed frogs have been reported in Arizona, California, Colorado, Florida, Louisiana, Nevada, New Mexico, North Carolina, Virginia, Wisconsin, and Wyoming. They were used in human pregnancy tests in the 1940s and 1950s. When a female African clawed frogs is injected with the urine of a pregnant woman, she begins laying eggs. When better techniques were discovered for determining if a woman was pregnant, the African clawed frogs were released into the wild. They were also introduced when people who kept them as pets released them, or when they escaped.
