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'.
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.
The long-toed salamander (Ambystoma macrodactylum, Baird 1849) [4] is a mole salamander in the family Ambystomatidae.This species, typically 4.1–8.9 cm (1 + 3 ⁄ 5 – 3 + 1 ⁄ 2 in) long when mature, is characterized by its mottled black, brown and yellow pigmentation, and its long outer fourth toe on the hind limbs.
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 broad head and short neck may have been a result of respiratory constraints. [6] Their jaws were lined with small, sharp, conical teeth and the roof of the mouth bore larger tusk-like teeth. The teeth were replaced in waves that traveled from the front of the jaw to the back in such a way that every other tooth was mature, and the ones in ...
The frog's eyes are on top of the head, looking upwards. The pupils are circular. They have no moveable eyelids, tongues (rather it is completely attached to the floor of the mouth [6]) or eardrums (similarly to Pipa pipa, the common Suriname toad [7]). [8] Unlike most amphibians, they have no haptoglobin in their blood. [8]
