Bryozoa anatomy

A Bryozoan's Medical Endosymbiont. The spiral-tufted bryozoan ( Bugula neritina) is being studied for a potential Alzheimer's disease and cancer drug—but it's not the bryozoan that makes the chemical. The chemical, found in the bryozoan's tissues, is produced by its bacterial endosymbiont, Candidatus Endobugula sertula. In exchange for a ...

In the present study, we investigate the mechanisms of survival and physiological adaptations due to desiccation and low temperatures in the statoblasts of two populations of the freshwater bryozoan Cristatella mucedo. Our results show that both sessoblasts and floatoblasts tolerate almost complete desiccation and subzero temperatures. In continuation of soft part anatomy of bryozoa is the reproductive portion of the zooid. Salt water bryozoa typically reproduce sexually. In the case of sexual reproduction, there two anatomical features that are needed. They are the ovaries and spermatozoa. Both of these features are found adjacent on each side of the stomach. Anatomy. The interior of the shell is lined with a mantle, a membranous duplication of the body wall, through which respiration may occur and which secretes the shells. The shell is closed and opened by adductor and diductor muscles respectively. The scars of these muscles may be seen on the inside of the valves.
