Filter feeders can play an important role in condensing biomass and removing excess nutrients (such as nitrogen and phosphate) from the local waterbody, and are therefore considered water-cleaning ecosystem engineers. They are also important in bioaccumulation and, as a result, as indicator organisms. Filter feeders can be sessile, planktonic ...
Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals) [6] are a phylum of simple, aquatic invertebrate animals, nearly all living in sedentary colonies. Typically about 0.5 millimetres (⁄64 in) long, they have a special feeding structure called a lophophore, a "crown" of tentacles used for filter feeding.
Barnacles are exclusively marine invertebrates; many species live in shallow and tidal waters. Some 2,100 species have been described. Barnacle adults are sessile; most are suspension feeders with hard calcareous shells, but the Rhizocephala are specialized parasites of other crustaceans, with reduced bodies.
Thelenota ananas, a giant sea cucumber from the Indo-Pacific tropics. Sea cucumbers are echinoderms from the class Holothuroidea (/ ˌhɒləˌθjʊəˈrɔɪdiə, ˌhoʊ -/ HOL-ə-thure-OY-dee-ə, HOHL-). They are marine animals with a leathery skin and an elongated body containing a single, branched gonad. They are found on the sea floor worldwide.
The term benthos, coined by Haeckel in 1891, [3] comes from the Greek noun βένθος 'depth of the sea'. [1][4] Benthos is used in freshwater biology to refer to organisms at the bottom of freshwater bodies of water, such as lakes, rivers, and streams. [5] There is also a redundant synonym, Benton. [6]
Lahille, 1890. Ascidiacea, commonly known as the ascidians or sea squirts, is a paraphyletic class in the subphylum Tunicata of sac-like marine invertebrate filter feeders. [2] Ascidians are characterized by a tough outer "tunic" made of a polysaccharide. Ascidians are found all over the world, usually in shallow water with salinities over 2.5%.
Chaetopterus or the parchment worm or parchment tube worm is a genus of marine polychaete worm that lives in a tube it constructs in sediments or attaches to a rocky or coral reef substrate. [ 1][ 2][ 3] The common name arises from the parchment -like appearance of the tubes that house these worms. [ 3] Parchment tube worms are filter feeders ...
The silver carp is a filter feeder, and possesses a specialized feeding apparatus capable of filtering particles as small as 4 μm. The gill rakers are fused into a sponge-like filter, and an epibranchial organ secretes mucus, which assists in trapping small particles. A strong buccal pump forces water through this filter.
