What is bryozoa
Bryozoans are colonial organisms, formed from repeated identical modules called zooids, and they can adopt forms ranging from encrusting to erect to massive ( ...Bryozoans are a primitive, ancient group of creatures whose fossil remains are found in rocks from long ago. While they are more abundant and common in marine environments, they have also adapted to freshwater habitats. Some estimates suggest that there are 20-25 species in North American freshwaters, but this is a bit unclear as this group is ...Bryozoan lineages were already quite diverse (multiple higher taxa) in the Early Ordovician when they are first observed in the fossil record. This supports the long held expectation that the phylum Bryozoa had its origin well before, in the Cambrian or earlier, and their first appearance in the fossil record is related to the advent of ...

Bryozoan colonies grow by budding from the adult zooids. New colonies will establish from a free-swimming, microscopic larval stage or by growth of dormant spore-like "statoblasts." Most Bryozoans live in salt water, and of the 20 or so freshwater species found in North America, most are found in warm-water regions attached to plants, logs ...Bryozoa is a phylum of usually sedentary colonial marine invertebrates. Colony morphologies are diverse, typically encrusting or branching, many of them calcified. In all species, the majority or totality of the colony is composed of (typically) box- or cylinder-shaped “autozooids,” which feed, providing nourishment for the colony. Bryozoans are stationary epifaunal suspension feeders. [3] Distribution. The majority of fossils of this genus are distributed throughout Europe and North America, but they have …Lophophorate phylums.

In living Bryozoa, each colony comprises a number of minute individuals (zooids) each with a crown of tentaclesprotrusible through an orifice and a body that is permanently attached within the exoskeleton.The skeletal structure of the entire colony is termed the zoarium (pl. zoaria) and this is composed of zooecia (sing. zooecium), the exoskeletons secreted by individual zooids.Bryozoans (Ordovician to today with no peak period) are animals that live in a colony and excrete a skeleton to support themselves. Sometimes the skeleton is made of minerals, and sometimes it is made of chitin. Bryozoans are primarily marine, but are sometimes found in tidal or delta environments. Each animal in the colony is called a zooid.Bryozoans form colonies by asexual budding from a primary zooid, or ancestrula, formed by metamorphosis of a sexually produced larva or from some kind of ...
