Another common feature of the phylum is the radial cleavage pattern, which may confirm the close relationship between brachiopods and phoronids or represent a plesiomorphic state. Nielsen (2002, p. 44) stated that ...Many familiar species belong to the phylum Arthropoda—insects, spiders, scorpions, centipedes, and millipedes on land; crabs, crayfish, shrimp, lobsters, and barnacles in water (Fig. 3.72).

SincePhylum Mollusca is the second largest phylum. A few molluscs such as Unio possess green glands which mimic the liver in vertebrates. They possess osphradia to test the chemical nature of water. The statocysts …Abstract. Brachiopods, a group of benthic suspension-feeding marine invertebrates, made their first appearance in the Lower Cambrian. In the Yangtze Platform (South China), well-exposed Lower Cambrian stratigraphic succession represents shallow to deeper water environments. Strata from eastern Yunnan, southern Shaanxi and the Yangtze gorges ...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.Brachiopods , phylum Brachiopoda, are a phylum of trochozoan animals that have hard "valves" on the upper and lower surfaces, unlike the left and right arrangement in bivalve molluscs. Brachiopod valves are hinged at the rear end, while the front can be opened for feeding or closed for protection. Two major categories are traditionally recognized, articulate and inarticulate brachiopods. The ... The tiny larval bryozoan is a clamlike swimmer in a bivalve shell. Opening its shell like an umbrella, it parachutes down onto a clean kelp blade. Alert for chemical cues, the bryozoan tests the surface, then cements itself to the blade with a sticky glue. The youngster settles in place and changes to its adult form, a captive within its own ... This phylum ranges from early Cambrian to Recent. Marine articulate brachiopods are first found in the early Cambrian, are abundant in Ordovician, Silurian, ...The Phylum Brachiopoda, which appeared in the Lower Cambrian Period, was one of the most abundant Paleozoic fossil phyla with over 30,000 species. That number has now dropped to 280 living species. The animal has two unequal valves which makes the brachiopod’s exoskeleton. They have a tiny heart with a poorly-developed circulatory system. Moss animal, any member of the phylum Bryozoa (also called Polyzoa or Ectoprocta), in which there are about 5,000 extant species. Another 15,000 species are known only from fossils.

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.Brachiopods are marine filter-feeding animals with two shells that hinged at the centre of the back.
