Bryozoa

Belongs within: Eumetazoa.Contains: Plumatella, Cheilostomata, Stenolaemata, Stoloniferina, Alcyonidium, Flustrellidae, Vesiculariidae, Arachnidiidae. The Bryozoa, sometimes known as moss animals or lace animals, are aquatic (mostly marine) minute colonial animals with the mouth surrounded by a ring of tentacles (the lophophore) and a U-shaped gut with the anus situated outside the lophophore. The lophophore can be retrated… Continue reading Bryozoa

Vesiculariidae

Belongs within: Bryozoa. The Vesiculariidae are a family of ctenostome bryozoans characterised by the presence of a distinct stolon. Members include the genus Vesicularia which has ovate, deciduous, distant zooecia that are contracted at the base and polypides possessing a gizzard (Harmer 1915). Characters (from Harmer 1915): Axis relatively thick, branching, tubular; zooecia directly attached to… Continue reading Vesiculariidae

Cheilostomata

Belongs within: Bryozoa.Contains: Calescharidae, Arachnopusioidea, Mamilloporoidea, Phidoloporidae, Celleporidae, Hippothoidae, Lepraliellidae, Catenicelloidea, Smittinidae, Lepraliomorpha, Flustridae, Cribrilinidae, Membraniporidae, Electridae, Bugulidae, Beaniidae, Candidae, Calloporidae, Thalamoporellidae. The Cheilostomata are a group of bryozoans in which the individual zooids are calcareous and box-like, and have a small orifice closed by a hinged, chitinous operculum (Prothero 1998). They have historically been… Continue reading Cheilostomata

Petraliellidae

Belongs within: Lepraliomorpha. Bryozoans get rooted Published 11 September 2022 Life as a sessile organism comes with its challenges. Whereas your mobile compatriots have the option to change their surroundings if conditions become difficult, you need to weather things as they come. You need a firm, broad foundation to achieve optimum growth. You need to… Continue reading Petraliellidae

Fenestrata

Belongs within: Cryptostomata.Contains: Fenestellidae. The Fenestrata are a group of bryozoans known from the Early Ordovician to the Permian. Fenestrates have zoaria arranged in a lacy network with short autozooids on one side of the zoarium, often with a hemiseptum at the base (Prothero 1998).

Trepostomata

Belongs within: Stenolaemata.Contains: Trematoporidae, Dyscritellidae, Stenoporidae, Ulrichotrypellidae, Cystoporata, Cryptostomata, Halloporina. The Trepostomata are a group of bryozoans known from the Ordovician to the Triassic, being particularly abundant during the Ordovician. Massive trepostome colonies form a dominant component of some Ordovician limestones (Prothero 1998). Characters (from Prothero 1998): Zoarium including three different forms of zooecia: autopores,… Continue reading Trepostomata

Cystoporata

Belongs within: Trepostomata. The Cystoporata are a group of bryozoans known from the Ordovician to the Triassic. Members of this group have curved partitions (cystiphragms) separating zooecia, and often crescentic projections (lunaria) around the apertures (Prothero 1998). <==Cystoporata |–Lichenalia [Rhinoporidae]T93 | `–L. concentrica Hall 1852T93 |–Botryllopora [Botrylloporidae]T93 | `–B. socialis Nicholson 1874T93 |–RevalotrypidaeT93 | |–Revalotrypa… Continue reading Cystoporata

Membraniporidae

Belongs within: Cheilostomata. The Membraniporidae are a family of cheilostome bryozoans with poorly calcified frontal walls and generally monomorphic zooids, and a twinned ancestrula (the initial pair of zooids in the colony) (Taylor & Monks 1997). The sea-mat Membranipora membranacea is widespread in temperate regions of the Atlantic and Pacific Oceans, where it grows encrusting… Continue reading Membraniporidae

Lepraliellidae

Belongs within: Cheilostomata. Lepraliellidae is a family of bryozoans (including both erect and encrusting forms) with relatively smooth frontals and an avicularium set in the proximal ring of the orifice (Gordon 1993). Lacy Lepraliellidae Published 10 May 2010 Lepraliellidae are a family of bryozoans (small colonial animals sometimes known as ‘lace animals’ or ‘moss animals’… Continue reading Lepraliellidae

Beaniidae

Belongs within: Cheilostomata. Beaniidae is a family of bryozoans forming reticulate sheets or diffuse uniserial colonies, loosely attached to their substratum or attached by rhizoids (Tilbrook et al. 2001). The frontal surface of the autozooids is generally membranous. <==Beaniidae |–Bugulella clavata Hincks 1887THG01 `–Beania Johnston 1840THG01 |–*B. mirabilis Johnston 1840THG01 |–B. bermudezi Lagaaij 1968T93 |–B.… Continue reading Beaniidae
