Overview

buccal force pump

Respiratory system, typical of the Amphibia, whereby air is forced into the lungs by raising the floor of the mouth while the valvular nostril is closed. Compare costal respiration.

...is no taxonomic difference between frogs and toads. Adults of all but one species ( Barbourula kalimantanensis , Bornean flat-headed toad) possess lungs, but breathe by expanding the throat to draw air through the nostrils then raise the floor of the mouth to force air into the lungs (buccal pumping). Most frogs lay eggs (frogspawn or toad spawn) in water, the eggs hatching into larvae called tadpoles (pollywogs). Larvae are typically herbivorous, most adults carnivorous. Frogs occur in moist habitats, but some species have adapted to dry conditions. They...

...crown and the base (pedicel). In fossils the crowns are often broken off here, leaving a cylindrical base with an open top. Pedicellate teeth are also found in a few temnospondyl labyrinthodonts believed to be closely related to modern amphibians. Living amphibians use a buccal force-pump mechanism for breathing. Air is forced back into the lungs by positive pressure from the mouth cavity. Amphibians have distinctive short ribs that do not form a complete rib cage as in amniotes. In contrast, amniotes use aspiration to fill the lungs, in which the rib cage...
