Triadobatrachus is an extinct genus of salientian frog-like amphibians, including only one known species, Triadobatrachus massinoti. It is the oldest member of the frog lineage known, and an excellent example of a transitional fossil. It lived during the Early Triassic about 250 million years ago, in what is now Madagascar.
The Guinness Book of World Records lists the frog's body weight at 10 milligrams (0.00035 oz), [13] while measurements of Schindleria brevipinguis show them to weigh less than 2 milligrams (7.1 × 10 −5 oz), with one adult specimen weighing just 0.7 milligrams. [14] The frog lives on land and its life cycle does not include a tadpole stage. [11]
The origin of the order name Anura—and its original spelling Anoures—is the Ancient Greek alpha privative prefix ἀν-(an-from ἀ-before a vowel) 'without', [6] and οὐρά (ourá) 'animal tail'. [7] meaning "tailless". It refers to the tailless character of these amphibians. [8] [9] [10] The origins of the word frog are uncertain and ...
Semiaquatic animals include: Vertebrates. Amphibious fish; also several types of normally fully aquatic fish such as the grunion and plainfin midshipman that spawn in the intertidal zone; Some amphibians such as newts and salamanders, and some frogs such as fire-bellied toads and wood frogs.
The average life expectancy of these frogs is five years, but they have been known to live longer than 20 years, [4] and they can grow to 1" to 1.5" long. African dwarf frogs can be mistaken for and are often sold as young African clawed frogs, of the genus Xenopus, which are larger and more aggressive than the dwarf. [citation needed]
The decline in amphibian and reptile populations has led to an awareness of the effects of pesticides on reptiles and amphibians. [177] In the past, the argument that amphibians or reptiles were more susceptible to any chemical contamination than any land aquatic vertebrate was not supported by research until recently. [ 177 ]
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 ...
In captivity, C. cranwelli and C. ornata are the most popular species, [4] along with the "fantasy frog", a captive-produced hybrid between C. cranwelli and C. cornuta.These frogs can live in a terrarium with a floor area 8-10 times the size of the frog. [4]
