The gray whale feeds mostly upon __________. Marine amphibians: a. Respiratory gas exchange is conducted through the thin, gas-permeable skin and the gills. Reptiles have repeatedly invaded marine environments despite their physiological constraints as air breathers. Finally, they become obligatory air-breathers at a young age and this enables them to survive low oxygen concentrations in many of their natural habitats (Graham 1997). 7.

With the exception of a few frog species that lay eggs on land, all amphibians begin life as completely aquatic larvae. Fish gills are organs that allow fish to breathe underwater. Both amphibians and reptiles show episodic breathing patterns that may be centrally generated, though they do respond to changes in oxygen supply. Like other amphibians, the frog exhibits gill respiration in the early stages of its life cycle. Gills … However, during the larval stage, frogs undergo lung development as they approach metamorphosis and rely very little on gill respiration; whereas, toads remain gill-breathers during the entire larval period (McDiarmid and Altig 1999). 6.
