The jaw of a mudpuppy also plays a significant role in its diet. The mudpuppy jaw is considered metaautostyly, like most amphibians, meaning the jaw is more stable and that the salamander has a dentary. [15] This affects their diet by limiting the flexibility of the jaw to take in larger prey.
The African clawed frog (Xenopus laevis), also known as simply xenopus, African clawed toad, African claw-toed frog or the platanna) is a species of African aquatic frog of the family Pipidae. Its name is derived from the short black claws on its feet. The word Xenopus means 'strange foot' and laevis means 'smooth'.
The only amphibians to bear claws are the African clawed frogs. Claws evolved separately in the amphibian and amniote (reptiliomorph) line. [12] However, the hairy frog has claw analogues on its feet; the frog intentionally dislocates the tips of its fingers to unsheathe the sharp points of its last phalanges.
The list below largely follows Darrel Frost's Amphibian Species of the World (ASW), Version 5.5 (31 January 2011). Another classification, which largely follows Frost, but deviates from it in part is the one of AmphibiaWeb , which is run by the California Academy of Sciences and several of universities.
Xenopus boumbaensis, the Mawa clawed frog, is a predominantly to fully aquatic species of frog in the family Pipidae, [3] [4] [5] known from a few localities in central and southern Cameroon, the northwestern Republic of the Congo and the extreme southwest of the Central African Republic.
This week, meet a shroom frog, explore an asteroid shaped by a NASA mission, marvel at a fish louder than elephant, get an update on Odie’s moon landing, and more.
Little is known about the longevity of frogs and toads in the wild, but some can live for many years. Skeletochronology is a method of examining bones to determine age. Using this method, the ages of mountain yellow-legged frogs ( Rana muscosa ) were studied, the phalanges of the toes showing seasonal lines where growth slows in winter.
Birds with teeth were common during the time of the dinosaurs, but a newly discovered species is changing the way scientists understand avian evolution.
