The African bullfrog is a voracious carnivore, eating insects and other invertebrates, small rodents, reptiles, small birds, fish, and other amphibians that can fit in their mouths. [5] [9] [10] It is also a cannibalistic species—the male African bullfrog is known for occasionally eating the tadpoles he guards, [11] and juveniles also eat ...
Most toxic amphibians are poisonous to touch or eat. These amphibians usually sequester toxins from animals and plants on which they feed, commonly from poisonous insects or poisonous plants . Except certain salamandrid salamanders that can extrude sharp venom-tipped ribs, [ 1 ] [ 2 ] and two species of frogs with venom-tipped bone spurs on ...
Pyxicephalus (πυξίς, pyxis = "(round) box," κεφαλή, kephalē = "head") is a genus of true frogs from Sub-Saharan Africa, commonly referred to as African bull frogs or bull frogs. [1] They are very large ( P. adspersus ) to large (remaining species) frogs, with females significantly smaller than males. [ 2 ]
Beytell’s bullfrogs are “large” and “robust,” reaching over 8 inches in length, the study said. Du Preez said the largest specimen weighed about 2.2 pounds. A Pyxicephalus beytelli, or ...
Frogs produce large quantities of dilute urine in order to flush out toxic products from the kidney tubules. [78] The nitrogen is excreted as ammonia by tadpoles and aquatic frogs but mainly as urea, a less toxic product, by most terrestrial adults. A few species of tree frog with little access to water excrete the even less toxic uric acid. [78]
The edible bullfrog is a large bodied frog in which the males typically reach 8.3–12 cm (3.3–4.7 in) in snout–to–vent length and the females 8.5–11 cm (3.3–4.3 in). [3] Exceptionally large males may even reach 13.8 cm (5.4 in), although the species does not approach the sizes attained by the related African bullfrog (P. adspersus). [4]
The Pyxicephalidae contain two subfamilies, with a total of 12 genera. [1] [2] This family was formerly considered part of the family Ranidae.[1]Family Pyxicephalidae ...
The family of Pyxicephalidae (African bullfrogs) has two subfamilies, 13 genera, and 68 total species. They are also found in Sub-Saharan Africa. The two subfamilies are completely different in that cacosternines are small and slender typically terrestrial or semiaquatic, whereas pyxicephalines are large bullfrog like frogs that have stocky ...
