Pipidae

Smooth clawed frog (Xenopus laevis)

The tongueless ( Pipidae ) are a family of frogs and toads ( Anura ). The name goes back to the missing tab. The eyes are lidless (except Pseudhymenochirus merlini, but only with dead animals recognizable); Horn teeth are missing. The presence of lateral line organs in the form of raised dermal papilla refers to the aquatile of life of the animals. During mating, the females are from the males in the groin clutching ( = inguinal amplexus ). The tadpoles have paired respiratory openings. First, they do not have floating ribs, but the overgrown after metamorphosis with the transverse processes of the vertebrae.

The frogs are common in Africa, Surinam toads in South America. Most species occur in waters of the tropical rainforests.

In particular, the genera Xenopus and Hymenochirus are often kept and bred in aquariums. Previously we used them for pregnancy tests, by injected them in the urine of women under the skin. Was this pregnant, the urine corresponding hormones that stimulated the frog to spawn contained (see details below clawed frog ).

For mating and brood care behavior of the Surinam Toads compare: tadpole.
