Amphibians,n land, most amphibians remain near ponds and streams; others remain wholly in water throughout life. In the majority of cases amphibians lay eggs in water, where they are fertilized, such eggs thenceforth developing into water-dwelling, gill-breathing larvae, essentially similar in form to their fi

Staging of Embryonic and Larval Amphibians,graphy, anatomy, and histology of the various organs and tissues are now available in the literature, most of them examined in lesser or greater detail to the level of electronmicroscopy. Analyses of ontogeny have also been made at the gross visual level, for a variety of reasons (.), and like a ser

During premetamorphosis there is no real effective level of hormonal secretion in the circulation (Myauchi et al., 1977) and thyroid activity is minimal (Etkin and Gona, 1974). From the end of premetamorphos

The first amphibians, distinguishable from fishes by structural differences that enabled them to survive for periods of time out of water, are found as fossils in the Devonian period of the Paleozoic era, about 35
