• Bryozoans • Characteristics of Phylum: – Small, colonial animals –– Some are encrusting forms, others form a branching Some are encrusting forms, others form a branching network that looks like a small tree Invertebrates • Brachiopods • Characteristics of Phylum: – Two shells or “valves ” enclose the bodyThe taccretion theory (or accretion) in astrophysics, explains that planets and other celestial bodies are formed by the condensation of small dust particles, attracted by the force of gravity. The idea that planets form this way was put forward by the Russian geophysicist Otto Schmidt (1891-1956) in 1944; He proposed that a huge cloud of gas ...Brachiopods and molluscs are lophotrochozoans with hard external shells which are often believed to have evolved convergently. While palaeontological data indicate that both groups are descended from biomineralising Cambrian ancestors, the closest relatives of brachiopods, phoronids and bryozoans, are mineralised to a much lower extent and are comparatively poorly represented in the ...

Asexual reproduction occurs by budding off new zooids as the colony grows, and is this the main way by which a colony expands in size. If a piece of a bryozoan colony breaks off, the piece can continue to grow and will form a new colony.A Anatomy and Physiology. A bryozoan colony is composed of identical linked animal units ( zooids ). An individual zooid consists of a partially protrusible organ system (= polypide) surrounded by a body wall. The polypide bears a large retractable lophophore with cilated tentacles used to collect food. 2 days ago · Major distinguishing characteristics: Lophophore and pedicle Approximate number of species described: between 300 and 500 extant Bryozoa [edit | edit source] A freshwater Bryozoan, species unknown.

Bryozoans are a classic "wild card" taxa, jumping around in otherwise stable phylogenies. They seem to be closer to Trochozoa than to Ecdysozoa or Deuterostomia in most molecular analyses. Alas, the bryozoan genome is as derived as its morphology, making it a difficult subject for molecular methods.
