The care of offspring among amphibians has been little studied but, in general, the larger the number of eggs in a batch, the less likely it is that any degree of parental care takes place. Nevertheless, it is estimated that in up to 20% of amphibian species, one or both adults play some role in the care of the young. [127]
All extant (living) amphibians belong to the monophyletic subclass Lissamphibia, with three living orders: Anura , Urodela (salamanders), and Gymnophiona . Evolved to be mostly semiaquatic , amphibians have adapted to inhabit a wide variety of habitats , with most species living in freshwater , wetland or terrestrial ecosystems (such as ...
They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. A list of amphibians organizes the class of amphibian by family and ...
The largest living amphibian is the 1.8 m (5 ft 11 in) South China giant salamander (Andrias sligoi), but this is dwarfed by prehistoric temnospondyls such as Mastodonsaurus which could reach up to 6 m (20 ft) in length. The study of amphibians is called batrachology, while the study of both reptiles and amphibians is called herpetology.
Desert ecology is the study of interactions between both biotic and abiotic components of desert environments. A desert ecosystem is defined by interactions between organisms, the climate in which they live, and any other non-living influences on the habitat. Deserts are arid regions that are generally associated with warm temperatures; however ...
The new study is a comprehensive view of their plight, assessing more than 93% of known amphibian species. It shows how humans are reshaping the world at a rapid rate and how climate change — a ...
Linnaeus, working from species-poor Sweden, where the common adder and grass snake are often found hunting in water, included all reptiles and amphibians in class "III – Amphibia" in his Systema Naturæ. [8] The terms reptile and amphibian were largely interchangeable, reptile (from Latin repere, 'to creep') being preferred by the French. [9]
The ASC's Stephen R. Edwards wrote Mammal Species of the World first and started Amphibian Species of the World second. Edwards decided to write about living amphibians because Richard G. Zweifel had just composed a large list of amphibian names and because experts from the University of Kansas were available to assist him.
