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.
Marine biology studies species that live in marine habitats. Most of the Earth's surface is covered by ocean, which is the home to marine life. Oceans average nearly four kilometers in-depth and are fringed with coastlines that run for about 360,000 kilometres. [4] [5] Marine biology can be contrasted with biological oceanography.
Aristotle's biology is the theory of biology, grounded in systematic observation and collection of data, mainly zoological, embodied in Aristotle's books on the science. Many of his observations were made during his stay on the island of Lesbos , including especially his descriptions of the marine biology of the Pyrrha lagoon, now the Gulf of ...
The development of marine biology as a scientific field was hampered by the incapacity to efficiently investigate these organisms in their native habitats. This problem was a significant pain point and was resolved by Villepreux-Power's idea, which helped scientists learn more about the biology and behavior of marine life.
If the deep marine hydrothermal setting was the site for the origin of life, then abiogenesis could have happened as early as 4.0-4.2 Gya. If life evolved in the ocean at depths of more than ten meters, it would have been shielded both from impacts and the then high levels of ultraviolet radiation from the sun.
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 ...
The Danish expedition to Arabia 1761–67 can be said to be the world's first oceanographic expedition, as the ship Grønland had on board a group of scientists, including naturalist Peter Forsskål, who was assigned an explicit task by the king, Frederik V, to study and describe the marine life in the open sea, including finding the cause of ...
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 .
