Pelagic Zone
Comb jellies live in various marine environments, from coastal waters to open oceans. They can be found in both shallow and deep waters around the world.
Organisms that live in open sea surfaces include phytoplankton (microscopic algae), zooplankton (tiny animals), fish, sea birds, and marine mammals such as dolphins and whales. These organisms are adapted to the dynamic and often nutrient-rich environment of open ocean waters.
This is very much a matter of the detail you wish to go into. Marine habitats can be divided into coastal and open ocean habitats. You might distinguish between warmer and colder surface waters, or the different levels of the deep sea such as benthic, demersal and pelagic. There are vast differences as habitats between a kelp bed and a coral reef.
Most productivity in open oceans is limited to surface waters primarily due to the availability of sunlight, which is essential for photosynthesis. Phytoplankton, the primary producers in marine ecosystems, thrive in the well-lit epipelagic zone (the upper layer of the ocean) where light penetrates. Below this layer, light diminishes rapidly, restricting photosynthetic activity and, consequently, the overall productivity of marine life. Additionally, nutrient availability tends to decrease with depth, further limiting productivity in the deeper ocean waters.
pelagic environment is a marine or freshwater envrionment that is not on the sea bed or river bed. A marine ecosystem can be divided into a benthic habitat (living off the sea bed, eg the coral reef) or pelagic (open waters) where the majority of fisheries may operate
'Marine' = to do with the sea and open ocean.
The open ocean is vast and expansive, typically characterized by deep blue waters. It can vary in appearance based on factors such as weather conditions and time of day. You may see calm waters or rough waves, marine life such as dolphins or whales, and distant horizons with no land in sight.
The marine biome is a more scientific way of saying "an ocean habitat". I haven't seen any sharks prancing through the deciduous forests or galloping over the open tundra lately. I must conclude that, yes, sharks live in the marine biome.
A marine-based ecozone is a geographic region characterized by its marine ecosystems and the physical factors that influence them, such as ocean currents, salinity levels, and temperature. These ecozones are defined by the marine species and habitats that are present and play a critical role in supporting diverse marine life. Examples of marine-based ecozones include coral reefs, kelp forests, and open ocean environments.
Cetaceans, which include whales, dolphins, and porpoises, primarily inhabit marine ecosystems. They are found in a variety of oceanic environments, ranging from coastal waters and bays to the deep sea. These ecosystems are characterized by diverse habitats, such as coral reefs, open ocean, and continental shelves, where cetaceans rely on abundant prey like fish and squid for food. Their presence also plays a crucial role in maintaining the health and balance of marine ecosystems.
A medusa, commonly known as a jellyfish, primarily lives in oceanic environments, ranging from the surface to the deep sea. They can be found in various marine habitats, including coastal areas, open waters, and sometimes estuaries. Some species may also inhabit brackish waters, but they are predominantly associated with saltwater environments.
