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 (1 ⁄ 64 in) long, they have a special feeding structure called a lophophore, a "crown" of tentacles used for filter feeding.
Stenolaemata are a class of exclusively marine bryozoans. Stenolaemates originated and diversified in the Ordovician, and more than 600 species are still alive today. [1] All extant (living) species are in the order Cyclostomatida, the third-largest order of living bryozoans. [2] These animals are stationary suspension feeders that live on the ...
Bryozoans are animals in the phylum Bryozoa. The phylum is subdivided in 3 classes: Phylactolaemata, Stenolaemata and Gymnolaemata. Subcategories.
The lophophore (/ ˈ l ɒ f ə ˌ f ɔːr, ˈ l oʊ f ə-/) [1] is a characteristic feeding organ possessed by four major groups of animals: the Brachiopoda, Bryozoa, Hyolitha, and Phoronida, which collectively constitute the protostome group Lophophorata. [2] All lophophores are found in aquatic organisms.
Archimedes is a genus of fenestrate bryozoans with a calcified skeleton of a delicate spiral-shaped mesh that was thickened near the axis into a massive corkscrew-shaped central structure. The most common remains are fragments of the mesh that are detached from the central structure, and these may not be identified other than by association ...
Heterotrypa, a trepostome bryozoan from the Corryville Formation (Upper Ordovician) in Covington, Kentucky. Bryozoans – half of all documented species of Bryozoa are fossils and extinct. [5] Class Stenolaemata / Gymnolaemata [!] (mostly marine, calcareous bryozoans): Order Cheilostomata [!] (living, rimmed-mouthed moss animals)
Fenestella is a genus of bryozoans or moss animals, forming fan–shaped colonies with a netted appearance. It is known from the Middle Ordovician to the early Upper Triassic , reaching its largest diversity during the Carboniferous. Many hundreds of species have been described from marine sediments all over the world.
Bryozoology is a branch of zoology specializing in Bryozoa, commonly known as moss animals, a phylum of aquatic invertebrates that live in clonal colonies.
