skeleton, the supportive framework of an animal body.The skeleton of invertebrates, which may be either external or internal, is composed of a variety of hard nonbony substances.The more complex skeletal system of vertebrates is internal and is composed of several different types of tissues that are known collectively as connective tissues.This designation …The origin of the brachiopods is uncertain; they either arose from reduction of a multi-plated tubular organism, or from the folding of a slug-like organism with a protective shell on either end. Since their Cambrian origin, the phylum rose to a Palaeozoic dominance, but dwindled during the Mesozoic . Origins Brachiopod fold hypothesis

Priapulida (priapulid worms, from Gr. πριάπος, priāpos 'Priapus' + Lat. -ul-, diminutive), sometimes referred to as penis worms, is a phylum of unsegmented marine worms.The name of the phylum relates to the Greek god of fertility, because their general shape and their extensible spiny introvert (eversible) proboscis may resemble the shape of a human …The phylum Cnidaria (pronounced “nih DARE ee uh”) includes soft-bodied stinging animals such as corals, sea anemones, and jellyfish (Fig. 3.23 A). The phylum’s name is derived from the Greek root word cnid- meaning nettle, a stinging plant.Cnidarians are found in many aquatic environments. Sea anemones are widely distributed, from cold arctic waters to the equator, …Shape and Symmetry of Brachiopoda: Brachiopoda are marine animals with a large lophophore consisting of a pair of coiled or folded arms bearing ciliated tentacles. The animal is enclosed in a bivalved shell. So they are commonly known as ‘Lamp shells’. The name Brachiopoda was coined by Dumeril (1806) (brachion-arm, podos-foot).Taxonomy - Classification, Organisms, Groups: Recent advances in biochemical and electron microscopic techniques, as well as in testing that investigates the genetic relatedness among species, have redefined previously established taxonomic relationships and have fortified support for a five-kingdom classification of living organisms.

(ed). (1982). Synopsis and Classification of Living Organisms. McGraw-Hill, New York. 2 volumes.Phylum Brachiopoda (lamp shells) has about 300 living species placed into two classes, Articulata and Inarticulata. More than 30,000 extinct species have been described.Brachiopods (from the Greek, meaning “arm-foot”), also known as lamp shells or the “other” bivalves,haveplayedacentralroleinbothgeologists’andbiologists’understandingofthehistory …Phylum Brachiopoda. Brachiopoda (brak-i-op´o-da) (Gr. brachion, arm, + pous, podos, foot), or lamp shells, are an ancient group. Although about 325 species are now living, some 12,000 fossil species, which once flourished in the Paleozoic and Mesozoic seas, have been described. Modern forms have changed little from early ones.The exact relationships between the different phyla are not entirely certain. The lophophores include groups that are united by the presence of the lophophore, a set of ciliated tentacles surrounding the mouth. Lophophorata include the flatworms and several other phyla, including the Bryozoa, Entoprocta, Phoronida, and Brachiopoda.Only about 300 to 500 species of brachiopods exist today, a small fraction of the perhaps 15,000 species (living and extinct) that make up the phylum Brachiopoda. Brachiopod shells come in a variety of shapes and sizes. Sometimes the bottom valve is convex like the top valve, but in many species the bottom valve is concave or occasionally conical.

Gibbons and Murray 1978 (Approved Lists 1980) The Bacillota (synonym Firmicutes) are a phylum of bacteria, most of which have gram-positive cell wall structure. [2] The renaming of phyla such as Firmicutes in 2021 remains controversial among microbiologists, many of whom continue to use the earlier names of long standing in the literature.

Lophophorata: This group includes the Phoronida and Entoprocta (both small groups) as well as the Bryozoa ("moss" animals) and Brachiopoda (brachiopods), both of which have an extensive fossil record. The feature shared by this group is the lophophore, an unusual feeding appendage bearing hollow tentacles.. While the Lophophorata are a well-recognized group, phylogenetic …For example, a previously classified group of animals called lophophorates, which included brachiopods and bryozoans, were long-thought to be primitive deuterostomes.

9. The brachiopods, phoronids and bryozoans were grouped under Tentaculata by Hatschek (1888) and under Lophophorata by Schneider (1902). 10. Because of the controversies regarding the systematic position, the brachiopods have been given the status of a separate phylum called Brachiopoda. Characteristic Features of Brachiopods: 1. The rotifers are a microscopic (about 100 µm to 30 mm) group of mostly aquatic organisms that get their name from the corona, a rotating, wheel-like structure that is covered with cilia at their anterior end (Figure 1).
