There are a number of ways in which the respiratory system has changed during the development of amphibians. Their respiratory system developed in such a way that they need more oxygen than they used to.
Amniotes (reptiles, mammals, birds) cannot change gender without major surgery and medication. Zebras are mammals, so they cannot naturally change gender. Some types of fish and amphibians change gender when exposed to certain pollutants, and some fish and invertebrates change gender naturally.
The change that was not part of the development and specialization of primitive mammals is the "development of bone." Primitive mammals primarily underwent changes such as specialization of teeth, an increase in overall body size, and an increase in stomach capacity, which were adaptations to their environments and dietary needs. Bone development was already a characteristic of early vertebrates and not a specialization unique to mammals.
Marine mammals respond to temperature change in various ways. In most cases, a change in temperature will cause the mammals to change their habitat.
Why does the respiratory rate change depending on age?
In the early stages of development, amphibians live in the water they breathe with gills as an adult an amphibian lives on land and uses lungs to breathe.
Whales transitioned from land-dwelling mammals to fully aquatic creatures, adapting to a marine habitat. This dramatic change involved evolving streamlined bodies, flippers, and specialized respiratory systems to thrive in ocean environments. Their habitat shift also included the development of sophisticated communication and navigation methods to locate food and socialize in vast ocean spaces.

metamorphosis
Metamorphosis is the change amphibians go throgh.I am a fourth grader just to tell you!
They become tadpoles
A change in the form and often habits of an animal during normal development after the embryonic stage. Metamorphosis includes, in insects, the transformation of a maggot into an adult fly and a caterpillar into a butterfly and, in amphibians, the changing of a tadpole into a frog.
