Do mammals live in water or land?
A majority of mammals live on land, although some are aquatic and some are aerial, and a few are “fossorial” (live underground). Of the land mammals, many live in trees and have larger limbs (and occasionally tails) to help them get from tree to tree. The primary species of aerial mammals is the bat.
Which mammals do not live on land?

Why fish Cannot live outside water?
Though some fish can breathe on land taking oxygen from air, most of the fish, when taken out of water, suffocate and die. This is because gill arches of fish collapse, when taken out of water, leaving the blood vessels no longer exposed to oxygen in air.
How many animals live in the ocean?
Ocean Life Scientists estimate that about one million species of animals live in the ocean. But most of them—95 percent—are invertebrates, animals that don’t have a backbone, such as jellyfish and shrimp.

What kind of animals live in the sea?
These animals have since evolved to be perfectly adapted to their environment. Most of these animals comprise a group known as the cetaceans, which includes the dolphins and whales. The other main group of marine mammals falls into the family of pinnipeds, which includes the seals and sea lions.
What kind of habitat does a marine mammal live in?
Most marine mammals, such as seals and sea otters, inhabit the coast. Seals, however, also use a number of terrestrial habitats, both continental and island.
What are the different types of marine mammals?
Marine mammals are classified into four different taxonomic groups: cetaceans (whales, dolphins, and porpoises), pinnipeds (seals, sea lions, and walruses), sirenians (manatees and dugongs), and marine fissipeds (polar bears and sea otters).
Are there any marine mammals that can walk on land?
Some marine mammals, such as polar bears and otters, have retained four weight-bearing limbs and can walk on land like fully terrestrial animals.
