12/5/2023 0 Comments Benthos abyssal zone animalsThese include snails, oysters, insects, amphipods, crayfish and the larvae of many aquatic insects (such as dragonflies, stoneflies, caddisflies, chironomid midges and blackflies). They live on or at the bottom of special reservoirs as some parts of their life. Large benthic animals (seen without a microscope) are called macrozoobenthos or macroinvertebrates. They are involved in recycling energy and essential nutrients.īenthos can be subdivided again based on size. Benthic microflora (such as bacteria, fungi and many protozoa) form dissociative communities. Zoobenthos, on the other hand, refers to all types of predators (such as benthic animals and protozoa). different types of algae and aquatic plants). The term phytobenthos is used to refer to the primary producer (e.g. Types of Benthic Communities(Mackie, 1998) These are usually invertebrates that can be filtered through a mesh size of 200-500 μm (Stickney 1984 Rosenberg and Resh 1993). Benthic macroinbertibrates are important fauna of freshwater, bay and marine aquatic ecosystems. Some Benthos live a part of their life cycle in other habitats such as beach. They live in a variety of water bodies, from small aquariums to the Mississippi River, the Great Lakes, and the ocean floor. Macroinvertebrates are part of the food chain that feeds many fish and other vertebrates in lakes and rivers. When benthos die, they decompose and release nutrients that are reabsorbed by plants and other animals.īenthic macroinvertebrates feed on algae and coarse organic matter (such as fallen leaves), fungi and bacteria, fine-suspended organic matter, and prey. Benthos plays an important role in maintaining natural energy flow and nutrient balance. Due to their abundance and location, they are known as middlemen in the aquatic food chain. Some eat benthos, leaves and other organic matter. Special knowledge on abundance, number of species and seasonal evolution is required for successful management of an aquatic ecosystem.īenthos are an important part of the food chain, especially for fish. The biological productivity of aquatic systems depends on the bioavailability of plankton and benthos. oysters) and deposit feeders (e.g., snails) (Ameen 1987). The sedimental organisms at the bottom of the basin are called benthos.īenthic animals can be divided into filter feeders (e.g. Such organisms live in flowing or stagnant water bodies and are also found in salt or freshwater habitats. Benthos refers to some aquatic organisms that live above, inside, or near the bottom of a body of water. The word ‘benthos’ comes from the Greek word ‘bathys’ which means depth.
