Bryozoa are a phylum of simple, aquatic invertebrate animals, nearly all living in sedentary colonies. Typically about 0.5 millimetres long, they have a special feeding structure called a lophophore, a "crown" of tentacles used for filter feeding. Most marine bryozoans live in tropical waters, but a few are found in oceanic trenches and polar waters. The bryozoans are classified as the marine bryozoans (Stenolaemata), freshwater bryozoans (Phylactolaemata), and mostly-marine bryozoans (Gymnolaemata), a few members of which prefer brackish water. 5,869 living species are known. At least two genera are solitary ; the rest are colonial.
Leaf warblers are small insectivorous passerine birds belonging to the genus Phylloscopus.
Stenolaemata are a class of exclusively marine bryozoans. Stenolaemates originated and diversified in the Ordovician, and more than 600 species are still alive today. All extant (living) species are in the order Cyclostomatida, the third-largest order of living bryozoans.
Cheilostomatida, also called Cheilostomata, is an order of Bryozoa in the class Gymnolaemata.
Cyclostomatida, or cyclostomata, are an ancient order of stenolaemate bryozoans which first appeared in the Lower Ordovician. It consists of 7+ suborders, 59+ families, 373+ genera, and 666+ species. The cyclostome bryozoans were dominant in the Mesozoic; since that era, they have decreased. Currently, cyclostomes seldom constitute more than 20% of the species recorded in regional bryozoan faunas.
Coccothrinax is a genus of palms in the family Arecaceae. There are more than 50 species described in the genus, plus many synonyms and subspecies. A new species was described as recently as 2017. Many Coccothrinax produce thatch. In Spanish-speaking countries, guano is a common name applied to Coccothrinax palms. The species are native throughout the Caribbean, the Bahamas, extreme southern Florida and southeastern Mexico, but most of the species are known only from Cuba.
Domingo Cullen was the governor of province of Santa Fe, Argentina during 1838.
A zooid or zoöid is a single animal that is part of a colonial animal. This lifestyle has been adopted by animals from separate unrelated taxa. Zooids are multicellular; their structure is similar to that of other solitary animals. The zooids can either be directly connected by tissue or share a common exoskeleton. The colonial organism as a whole is called a zoon, plural zoa.
Ascophora is an infraorder under order Cheilostomatida of the Bryozoa.
The ascus is a diagnostic morphological feature of the bryozoan suborder Ascophora. It is a water-filled sac of frontal membrane opening (ascopore) at or near the zooid orifice. It functions as a hydrostatic system by allowing water into the space below the inflexible, calcified frontal wall when the zooid everts its polypide by muscles pulling the frontal membrane inwards. The ascus, along with a calcified frontal shield, define ascophoran bryozoa.
Malacostegina is a sub-order of marine, colonial bryozoans in the order Cheilostomatida. The structure of the individual zooids is generally simple, with an uncalcified, flexible frontal wall. This sub-order includes the earliest known cheilostome, in the genus Pyriporopsis (Electridae).
Alan H. Cheetham is a paleobiologist and retired senior scientist and curator of invertebrate paleontology at the Smithsonian Institution's National Museum of Natural History.
The Ctenostomatida are an order of bryozoans in the class Gymnolaemata. The great majority of ctenostome species are marine, although Paludicella inhabits freshwater. They are distinguished from their close relatives, the cheilostomes, by their lack of a calcified exoskeleton. Instead, the exoskeleton is chitinous, gelatinous, or composed only of a soft membrane, and always lacks an operculum. Colonies of ctenostomes are often composed of elongated, branch-like stolons, although more compact forms also exist.
Ferdinand Canu (1863–1932) was a French paleontologist and author. In 1923 he was awarded Daniel Giraud Elliot Medal for his work North American Later Tertiary and Quaternary Bryozoa.
Stomachetosella is a genus of marine, filter-feeding invertebrates, known as bryozoa, belonging to the order Cheilostomatida. The genus name derives from the Latin stoma, meaning "mouth," and ochetos, meaning "small canal."
Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 2015.
Callopora lineata is a species of colonial bryozoan in the family Calloporidae. It is found on rocky shores in the Atlantic Ocean and the Mediterranean Sea.
Notiolofos is an extinct genus of sparnotheriodontid ungulate from the order Litopterna. The animal lived during the Eocene, in modern-day Antarctica. The genus contains two species, N. arquinotiensis, the type species, and N. regueroi.
Eliza Catherine Jelly was an English bryozoologist. She was one of the first women to work and publish in the field of bryozoology. Her 1889 text The Synonymic Catalogue of the Recent Marine Bryozoa is still used as a reference material.
