Oviduct structure and function and reproductive modes in amphibians. The structure and function of the oviducts of members of the three Orders of the Class Amphibia (Anura, frogs and toads; Urodela, salamanders and newts; Gy... MH Wake,R Dickie - 《Journal of Experimental Zoology Part A Ecolo...
Modern amphibians include the Anura (frogs and toads), the Urodela (salamanders) and the Apoda (caelicians). All are ectothermic,Answer and Explanation: As the name amphibian indicates, these animals are able to live in two types of environment, namely, water and land. Amphibian eggs are...
Large populations of cane toads can be found around the world. In the early 20th century several countries introduced the species to control crop-eating insects. The species’ expansion has been well documented, and cane toads are now considered to be one of the most invasive species. ...

These three orders of livingamphibiansare thought to derive from a single radiation of ancient amphibians, and although strikingly different in body form, they are probably the closest relatives to one ...
Amphibians are cold-blooded vertebrates belonging to the classAmphibia, including all frogs, toads, salamanders, newts, and caecilians. They spend part of their lives in water and the rest mostly on land. In fact, the word ‘amphibian’ comes from a Greek word meaning ‘both lives’, referrin...
amphibians include ectothermic tetrapods such as frogs toads and salamanders. the distinguishing feature that separates amphibians from reptiles is their breeding behaviour. most amphibians need a body of water to breed as their eggs are shell-less. furthermore, they undergo metamorphosis where the ...
Characteristics of Reptiles Excrete nitrogenous wastes in the form of uric acid. In the body, uric acid is much less toxic than ammonia or urea. Thus, it requires little water for dilution, and reptiles lose only small amounts of water in their urine. ...
Other large animals that inhabit areas of the Rockies are Bighorn sheep, mountain goats, varieties of deer (including caribou), and elk. Wild horses may inhabit adjacent plain areas. Small animals include varieties of chipmunks and squirrels, marmots, frogs, toads, salamanders, and snakes. ...
For wood frogs (L. sylvaticus), all of the variables predicting survival had confidence intervals that included zero, but very low survival may have limited our ability to estimate parameters. The terrestrial environment was important for predicting survival in both American toads (Anaxyrus americanus...
