Name three ways the environment in the ocean is different than life on land.

Explanation:

Marine organisms produce over half of the oxygen that land animals currently need to breathe. ... Most sea animals extract oxygen directly from ocean water, while land animals breathe air from Earth's atmosphere, which consists of about 21 percent pure oxygen

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.
