Polykrikos
''Polykrikos'' (from Greek “poly” - many, and “krikos” – ring or circle) is one of the genera of family Polykrikaceae that includes athecate pseudocolony-forming dinoflagellates. ''Polykrikos'' are characterized by a sophisticated ballistic apparatus, named the nematocyst-taeniocyst complex, which allows species to prey on a variety of organisms. ''Polykrikos'' have been found to regulate algal blooms as they feed on toxic dinoflagellates. However, there is also some data available on Polykrikos being toxic to fish. History of knowledge ''Polykrikos'' was first seen in 1868 by Uljanin and was mistakenly considered as a metazoan larva of a turbellarian flatworms. In 1873 Butschili re-examined the specimen and concluded that the cell was an unusual ciliate, and Bergh later, in 1881, clarified ''Polykrikos'' dinoflagellate affinities. Morphology ''Polykrikos'' is a colony of zooids (units of a colonial organism) that carry out simultaneous functions of a whole cell. ...

Polykrikaceae
The Polykrikaceae (also known as Polykrikidae) are a family of athecate dinoflagellates of the order Gymnodiniales. Members of the family are known as polykrikoids. The family contains two genera: '' Polykrikos'' and '' Pheopolykrikos''. Characteristics The most distinctive feature of polykrikoids is their formation of multinucleate "pseudocolonies" consisting of an even number of subunit zooids. The two genera differ in number of nuclei; possessing two nuclei regardless of the number of zooids is a synapomorphy for ''Polykrikos'', whereas ''Pheopolykrikos'' possess equal numbers of nuclei and zooids. Along with the Warnowiaceae (warnowiids), polykrikoids are known for possessing unusually complex subcellular structures. In particular, an extrusome complex of two organelles called the nematocyst and taeniocyst is considered a synapomorphy for ''Polykrikos''. Molecular phylogenetics studies suggest some inconsistency in the taxonomy of this group, particularly in the assig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polykrikos Kofoidii
''Polykrikos kofoidii'' is a species of phagotrophic marine pseudocolonial dinoflagellates that can capture and engulf other protist prey, including the toxic dinoflagellate, ''Alexandrium tamarense''. ''P. kofoidii'' is of scientific interest due to its status as a predator of other dinoflagellates, a behavior that is significant in the control of algal blooms. It has a complex life cycle of both vegetative (asexual) and sexual reproduction complicated by its pseudocolonial structure.
