Tongueless | Frog

The "tongueless frog" refers to the family , a unique group of primitive, highly specialized aquatic frogs found in South America and Sub-Saharan Africa. Unlike most amphibians, members of Pipidae lack a tongue and instead use a specialized feeding mechanism called suction feeding to capture prey. Overview of Pipidae

The Pipidae family consists of roughly 32 species, with the most well-known being the African clawed frog (Xenopus laevis) and the Surinam toad (Pipa pipa) . : Strictly aquatic throughout their lives.

: Detail how species like Pipa pipa use long, sensitive fingers to "corral" fish into their mouths.

: They often have flattened bodies, webbed feet, and claws on their toes.

Note the genome evolution of Xenopus , which is a primary model organism in developmental biology.

Thesis: The tongueless condition is not a deficit but an adaptation to a fully aquatic lifestyle.

Examine their role as both predators and prey in tropical freshwater systems.

: Explain how these frogs expand their throat to suck in water and prey.
