4 days ago · While the conclusions often show a high degree of coevolution and cospeciation, the genus- and species-level taxonomy is still permeated by the assumption, influenced by the old literature, that a single parabasalian species can be found in many unrelated hosts. Molecular data have shown that this is rarely the case (James, Tai, et al., 2013).
2 hours ago · A few are endosymbionts in lichens, plants, various protists, or sponges and provide energy for the host. Some live in the fur of sloths, providing a form of camouflage. Aquatic cyanobacteria are known for their extensive and highly visible blooms that can form in both freshwater and marine environments. The blooms can have the appearance of ...
1 day ago · Taxonomy. Carl Linnaeus, who classified most kinds of sessile animals as belonging to the order Zoophyta in the class Vermes, mistakenly identified the genus Spongia as plants in the order Algae.
5 days ago · This convenient division is not without fault, for, strictly speaking, many planktonic organisms are neither clearly plant nor animal but rather are better described as protists. When size is used as a criterion , plankton can be subdivided into macroplankton, microplankton, and nannoplankton, though no sharp lines can be drawn between these ...

4 days ago · Protists exhibit incredible diversity, with more than 200,000 known species. They come in various shapes and sizes , ranging from microscopic single cells to larger multi-cellular organisms. This vast array of forms and structures makes the study of protists a fascinating and challenging field.
3 days ago · 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 ( in) long, they have a special feeding structure called a lophophore, a "crown" of tentacles used for filter feeding.
