Amphibians | OpenStax Biology 2e - Lumen Learning All amphibians are carnivores and possess many small teeth The fossil record provides evidence of amphibian species, now extinct, that arose over 400 million years ago as the first tetrapods Living Amphibia can be divided into three classes: salamanders (Urodela), frogs (Anura), and caecilians (Apoda)
Amphibian behavioral diversity offers insights into . . . Amphibians are a diverse class of vertebrates comprising more than 8000 extant species and classified into three orders (Figure 1): gymnophiona (caecilians); urodela (salamanders and newts); and anura (frogs and toads)
Overview of Amphibians - Exotic and Laboratory Animals . . . The class Amphibia has >7500 described species, including 3 orders: Anura (Salientia), Caudata (Urodela), and Gymnophiona (Apoda) Anura refers to tailless amphibians and is the largest order, comprising >6000 species, including frogs and toads (see Table: Similarities and Differences Between Frogs and Toads
ADW: Anura: INFORMATION They are found throughout most of the world, except in polar regions, and some oceanic islands and extremely xeric deserts Anuran diversity is greatest in the tropics Twenty-five families are currently recognized, representing more than 4,000 species, with more being discovered regularly
The Scientific Name for a Frog: Explained - Vital Frog Scientific names also play a crucial role in the classification of frogs Frogs belong to the class Amphibia, which includes other amphibians like salamanders, newts, and caecilians The class Amphibia is further divided into several orders, with the order Anura encompassing all the different frog species
Clades of Amphibians | Biology for Majors II - Lumen Learning Amphibia comprises an estimated 6,770 extant species that inhabit tropical and temperate regions around the world All living species are classified in the subclass Lissamphibia (“smooth-amphibian”), which is divided into three clades: Urodela (“tailed”), the salamanders; Anura (“tail-less”), the frogs; and Apoda (“legless ones”), the caecilians
