Tonugeless Frogs of the United States

One species, Xenopus laevis, has been introducted in North America.

Tongueless frogs have attached ribs and eight presacral vertebrae. Their pupils are round. The South American species have starlike projections on the tips of the toes of the front feet while the African species have simple pointed toes on the front feet. The latter attach their eggs singly to submerged vegetation, logs, or stones. Thousands of eggs are laid at a time. During breeding, the male clasps the female around the waist.


There is one species of Tonugeless Frogs in the U.S.

African Clawed Frog (Xenopus laevis)
