The animal is responding to its environment.

Aquatic frogs such as the leopard frog(Rana pipiens) and American bullfrog (Rana catesbeiana) typically hibernate underwater. A common misconception is that they spend the winter the way aquatic turtles do, dug into the mud at the bottom of a pond or stream. In fact, hibernating frogs would suffocate if they dug into the mud for an extended period of time. A hibernating turtle's metabolism slows down so drastically that it can get by on the mud's meager oxygen supply. Hibernating aquatic frogs, however, must be near oxygen-rich water and spend a good portion of the winter just lying on top of the mud or only partially buried. They may even slowly swim around from time to time.

Characteristics that are used to divide aquatic biomass into three zones include whether the water is fresh or salt and if the water moves. Fast moving and slow moving water are classified differently.
Basidiomycota are either unicellular or multicellular, sexual or asexual, and terrestrial or aquatic organisms. They obtain nutrition from decaying dead organic matter.
a frog is an amphibian. one of their characteristic is that their skin is moist and since they are partially aquatic animals they could die without water.
One unique characteristic distinguishing animals from members of other kingdoms is animals have more complex and rapid movements. The movement of sponges isn't more complex.
The ocean is not aquatic, it is marine. Aquatic is freshwater. Marine is saltwater.
No. Aquatic plants do not have gills. Aquatic vertebrates, such as fish, have gills.
