Magic and Gracie off Castle Garden, painted by James E. Buttersworth, c. 1871. Maritime history is the study of human interaction with and activity at sea. It covers a broad thematic element of history that often uses a global approach, although national and regional histories remain predominant.
Turbinaria is a genus of brown algae (Phaeophyceae) found primarily in tropical marine waters. It generally grows on rocky substrates. [1] In tropical Turbinaria species that are often preferentially consumed by herbivorous fishes and echinoids, there is a relatively low level of phenolics and tannins.
Coral reefs are one of the most well-known marine ecosystems in the world, with the largest being the Great Barrier Reef.These reefs are composed of large coral colonies of a variety of species living together.
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 Mediterranean Sea (/ ˌ m ɛ d ɪ t ə ˈ r eɪ n i ən / MED-ih-tə-RAY-nee-ən) is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the east by the Levant in West Asia, on the north by Anatolia in West Asia and Southern Europe, on the south by North Africa, and on the west almost by the Morocco–Spain border.

General characteristics of a large marine ecosystem (Gulf of Alaska) Killer whales (orcas) are highly visible marine apex predators that hunt many large species. But most biological activity in the ocean takes place with microscopic marine organisms that cannot be seen individually with the naked eye, such as marine bacteria and phytoplankton.
