Devonian North America once again was home to seas that teemed with life. In fact Devonian marine life may have been more abundant and diverse than at any other point in the Paleozoic. [22] Glass sponges became abundant in western New York during the Devonian. [23] Especially notable are the marine fossils of Cuyahoga County, Ohio, which was ...
Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons ...
General characteristics of a large marine ecosystem (Gulf of Alaska). Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal ...
Marine biology is the scientific study of the biology of marine life, organisms that inhabit the sea. Given that in biology many phyla , families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy .

The History of North America encompasses the past developments of people populating the continent of North America. While it was commonly accepted that the continent first became inhabited by humans when individuals migrated across the Bering Sea 40,000 to 17,000 years ago, [ 1 ] more recent discoveries may have pushed those estimates back at ...
Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms. [58]
The first recorded observations on the distribution and habits of marine life were made by Aristotle (384–322 BC). [3] Observations made in the earliest studies of marine biology provided an impetus for the age of discovery and exploration that followed. During this time, a vast amount of knowledge was gained about life that exists in the oceans.
