gills
Some of the adaptations that allow fish to live in the water are gills, fins, and scales. The gills allow the fish to live in the water. The gills allow the fish to extract oxygen from the water. The fins allow the fish to swim through the water and help it stear itself. For the scales I'm not sure!
The answer is A) live in different environments
Gill and fins,scales
land mammals live on land, sea mammals live in the water.
Seals are marine mammals and do not live 'in Antarctica': Antarctica is a continent. Seals survive in their natural habitat, water, which surrounds Antarctica in the form of the Southern Ocean.
Mammals give birth to live young and typically care for their offspring, while amphibians lay eggs in water and often do not provide parental care. Mammals have adaptations such as fur and mammary glands for terrestrial environments, while amphibians have moist skin and lay eggs in water for their aquatic lifestyle.
because they cannot live out of the water and yes they are mammals!!
Aquatic mammals are mammals that can swim and live in water if necessary.

Yes, mammals like Manatee, dugong, whales and dolphins all live in salt water.
