Question

How are aquatic animals and terrestrial animals adapted to survive?

Answer 1

Answer:

In terrestrial habitats they are subjected to daily and seasonal variation in temperature and water availability. Their success in colonizing different habitats is due to physiological, behavioral, and morphological adaptations to water availability, as well as ionic and thermal balance.

Aquatic animals also have adaptations to regulate temperature, since water transfers heat faster than air. Sea otters use a layer of air pockets combined with oily fur to stay warm. Oxygen is transferred from water through organs called gills in fish, sharks, and rays.
