Foxfire in the fungus Panellus stipticus Blue ocean glow caused by myriad tiny organisms, such as Noctiluca. Noctiluca scintillans, a bioluminescent dinoflagellate. Bioluminescence is the production of light by living organisms. This list of bioluminescent organisms is organized by the environment, covering terrestrial, marine, and microorganisms.
Marine ecosystems are characterized by the biological community of organisms that they are associated with and their physical environment. Classes of organisms found in marine ecosystems include brown algae, dinoflagellates, corals, cephalopods, echinoderms, and sharks. Marine ecosystems are important sources of ecosystem services and food and ...
Marine invertebrates are the invertebrates that live in marine habitats. Invertebrate is a blanket term that includes all animals apart from the vertebrate members of the chordate phylum. Invertebrates lack a vertebral column, and some have evolved a shell or a hard exoskeleton.
Marine mammals are mammals that rely on marine (saltwater) ecosystems for their existence. They include animals such as cetaceans ( whales, dolphins and porpoises ), pinnipeds ( seals, sea lions and walruses ), sirenians ( manatees and dugongs ), sea otters and polar bears. They are an informal group, unified only by their reliance on marine ...
The animals rooted to or living on the ocean floor are not pelagic but are benthic animals. [147] Life within the ocean evolved 3 billion years prior to life on land. Both the depth and the distance from shore strongly influence the biodiversity of the plants and animals present in each region. [148]
Aquatic plants are plants that have adapted to living in aquatic environments ( saltwater or freshwater ). They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes. A macrophyte is a plant that grows in or near water and is either emergent, submergent, or floating.
Wildlife of Iceland. The wildlife of Iceland is the wild plant and animal life found on the island of Iceland, located in the north Atlantic Ocean just south of the Arctic Circle. The flora, fauna, and funga is limited by the geography and climate of the island. The habitats on the island include high mountains, lava fields, tundras, rivers ...
From shallow waters to the deep sea, the open ocean to rivers and lakes, numerous terrestrial and marine species depend on the surface ecosystem and the organisms found there. The ocean's surface acts like a skin between the atmosphere above and the water below, and hosts an ecosystem unique to this environment.
