How are the benthic zones divided?
The benthic environment is also divided into zones, most of which correspond to the pelagic divisions: The supralittoral zone lies above the high tide line. Also called the spray zone, it is only submerged during storms or unusually high waves. The littoral zone is the region between the high and low tides.
What is considered benthic?
The word benthos comes from a Greek term meaning “depths of the sea.” Benthic communities are complex and include a wide range of animals, plants and bacteria from all levels of the food web. Clams, worms, oysters, shrimp-like crustaceans and mussels are all examples of benthic organisms.
What are the pelagic zones from shallow to deep?
The ocean is divided into five zones: the epipelagic zone, or upper open ocean (surface to 650 feet deep); the mesopelagic zone, or middle open ocean (650-3,300 feet deep); the bathypelagic zone, or lower open ocean (3,300-13,000 feet deep); the abyssopelagic zone, or abyss (13,000-20,000 feet deep); and the …
What does pelagic mean what are the pelagic zones from shallow to deep?
The pelagic zone is the part of the open sea or ocean comprising the water column, i.e., all of the sea other than that near the coast or the sea floor. In contrast, the demersal zone comprises the water that is near to (and is significantly affected by) the coast or the sea floor.
What is the depth of the benthic zone?
The benthic zone starts at the shore and extends down along the bottom of the lake or ocean. This means that it could be as shallow as a few inches at its start, but may reach depths of 6,000 meters as it coincides with the abyssal plain at the bottom of the ocean.
What is the benthic division?
A primary division of the sea that includes all of the ocean floor.
What is marine benthic?
Marine Benthic Invertebrates Organisms living in or on the sediment on the seafloor are called benthos. Marine benthic invertebrate communities are dominated by polychaete annelids, molluscs, crustaceans, and echinoderms, but include members of many lesser known animal phyla.
What is the benthic layer in an aquatic biome?
The benthic zone is the ecological region at the lowest level of a body of water. It starts at the shoreline and continues down until it reaches the floor, encompassing the sediment surface and sub- surface layers. Although this zone may appear barren, it plays a vital role in the health of aquatic ecosystems.
