Seaweeds can be found in the following groups ... Seaweed, or macroalgae ... The deepest living seaweed are some species of red algae.
Posidonia oceanica is a flowering plant which grows in dense meadows or along sandy channels in the waters of the Mediterranean. It is found at depths of 1–35 metres (3.3–114.8 ft), [8] depending on water clarity. Subsurface rhizomes and roots stabilize the plant, while erect rhizomes and leaves reduce silt accumulation.
Environments in which subsurface life has been found [1]. The deep biosphere is the part of the biosphere that resides below the first few meters of the ocean's surface. It extends down below 10 kilometers below the continental surface and 21 kilometers below the sea surface, at temperatures that may reach beyond 120 °C (248 °F) [2] which is comparable to the maximum temperature where a ...
Scientists working in the Antarctic region have discovered a type of seaweed living at depths some 100 metres below the surface. Researchers hailed the discovery of red alga Palmaria decipiens ...
A new study of biological markers contained in fossilized plaque found that, before they largely disappeared from Western diets, different types of seaweed were once a staple food for Europeans ...
Kelp forests occur worldwide throughout temperate and polar coastal oceans. [1] In 2007, kelp forests were also discovered in tropical waters near Ecuador. [4] Global distribution of kelp forests. "I can only compare these great aquatic forests ... with the terrestrial ones in the intertropical regions. Yet if in any country a forest was ...
Deep-water coral Paragorgia arborea and a Coryphaenoides fish at a depth of 1,255 m (4,117 ft) on the Davidson Seamount. The habitat of deep-water corals, also known as cold-water corals, extends to deeper, darker parts of the oceans than tropical corals, ranging from near the surface to the abyss, beyond 2,000 metres (6,600 ft) where water temperatures may be as cold as 4 °C (39 °F).
Pelagic fish. Pelagic fish live in the pelagic zone of ocean or lake waters—being neither close to the bottom nor near the shore—in contrast with demersal fish that live on or near the bottom, and reef fish that are associated with coral reefs. [ 1 ] The marine pelagic environment is the largest aquatic habitat on Earth, occupying 1,370 ...
