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 .
Bryozoology is a branch of zoology specializing in Bryozoa, commonly known as moss animals, a phylum of aquatic invertebrates that live in clonal colonies.
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)
Bryozoans are animals in the phylum Bryozoa. The phylum is subdivided in 3 classes: Phylactolaemata, Stenolaemata and Gymnolaemata. The phylum is subdivided in 3 classes: Phylactolaemata, Stenolaemata and Gymnolaemata.
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.
Graptolite fossils were later referred to a variety of groups, including other branching colonial animals such as bryozoans ("moss animals") and hydrozoans. The term Graptolithina was established by Bronn in 1849, who considered them to represent orthoconic cephalopods.
Meanwhile, a trip to Aspen, Colorado, transformed my definition of luxury. In Paris and New York, five-star hotels and Michelin-star restaurants coexist alongside $1 pizza and cheap crepe carts.
Phylactolaemata [1] is a class of the phylum Bryozoa whose members live only in freshwater environments. Like all bryozoans, they filter feed by means of an extensible "crown" of ciliated tentacles called a lophophore, and like nearly all bryozoans (the only known exception being Monobryozoon), they live in colonies, each of which consists of clones of the founding member.
