The ocean is broadly divided into three zones depending on thelight levels. The sunlight, or euphotic, zone spans from the water's surface to around 656 feet, where enough light for photosynthesis penetrates the water. The depths deep-sea plants can reach vary with the light levels in...
Deep-sea fish, in general, any species of fishes (class Osteichthyes) that are found at extreme ocean depths, usually more than 600 m and even to as much as 8,370 m (that is, about 2,000 to 27,500 feet). Mid-water species, which represent more than a doz
The deep sea (or deep layer) is the lowest layer in the ocean. Little or no light penetrates this part of the ocean, and most of the organisms that live there rely for subsistence on falling organic matter. Furthermore, most deep ocean waters have sufficient oxygen to support life. ...

Southern OceanA verdict by the International Hydrographic Organization in the spring of 2000 delimited a fifth world ocean - the Southern Ocean - from the southern portions of the Atlantic Ocean, Indian Ocean, and Pacific Ocean. The Southern Ocean extends from the coast of Antarctica north to 60...
A total of 46 novel fungal OTUs were recovered, including a novel Zygomycete lineage.The Mariana Trench area also harbors a diverse fungal community in deep-sea sediments.28S rDNA is an efficient target gene to describe fungal community in the deep-sea environment.Different parts of rDNA region...
In six of the ocean's deepest crevasses, scientists found tiny shrimp-like creatures chomping on tiny bits of plastic.
The ocean floor is home to many unique communities of plants and animals.海底是许多独特的动植物群落的家园。Most of these marine ecosystems are near the water surface, such as the Great Barrier Reef, a 2.000km long coral formation off the northeaster coast of Australia.这些海洋生态系统大多位于...
