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 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 ...
Handling the newts does no harm, but ingestion of even a minute fragment of skin is deadly. In feeding trials, fish, frogs, reptiles, birds, and mammals were all found to be susceptible. [16] Mature adults of some salamander species have "nuptial" glandular tissue in their cloacae, at the base of their tails, on their heads or under their chins.
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.
WASHINGTON (Reuters) - There definitely were no muppets during the Permian Period, but there was a Kermit - or at least a forerunner of modern amphibians that has been named after the celebrity frog.
Bullfrog stomachs have been found to contain rodents, small lizards and snakes, other frogs and toads, other amphibians, crayfish, other crustaceans, [47] small birds, scorpions, tarantulas and bats, [48] [49] as well as the many types of invertebrates, such as snails, worms and insects, which are the usual food of ranid frogs.

Genetic evidence and some anatomical details (such as pedicellate teeth) support the idea that frogs, salamanders, and caecilians (collectively known as lissamphibians) are each other's closest relatives. Frogs and salamanders show many similarities to dissorophoids, a group of extinct amphibians in the order Temnospondyli. Caecilians are more ...
Blue poison dart frog. Herpetology (from Greek ἑρπετόν herpetón, meaning "reptile" or "creeping animal") is a branch of zoology concerned with the study of amphibians (including frogs, salamanders, and caecilians (Gymnophiona)) and reptiles (including snakes, lizards, turtles, crocodilians, and tuataras).
