The silicoflagellates are a small group of unicellular photosynthetic protists, or algae, belonging to the supergroup of eukaryotes known as Stramenopiles. They behave as plankton and are present in oceanic waters. They are well-known from harmful algal blooms that cause high mortality of fish. Additionally, they compose a rich fossil record represented by their silica skeletons.
The axodines are a group of unicellular stramenopiles that includes silicoflagellate and rhizochromulinid algae, actinomonad heterotrophic flagellates and actinophryid heliozoa. Alternative classifications treat the dictyochophytes as heterokont algae, or as Chrysophyceae. Other overlapping taxonomic concepts include the Actinochrysophyceae, Actinochrysea or Dictyochophyceae sensu lato. The grouping was proposed on the basis of ultrastructural similarities, and is consistent with subsequent molecular comparisons.
Stentor, sometimes called trumpet animalcules, are a genus of filter-feeding, heterotrophic ciliates, representative of the heterotrichs. They are usually horn-shaped, and reach lengths of two millimeters; as such, they are among the largest known extant unicellular organisms. They reproduce asexually through binary fission.
The Cymothoidae are a family of isopods in the suborder Cymothoida found in both marine and freshwater environments. Cymoithoids are ectoparasites, usually of fish, and they include the bizarre "tongue-biter", which attaches to a fish's tongue, causing it to atrophy, and replaces the tongue with its own body. Ceratothoa oestroides is one of the most devastating ectoparasites in Mediterranean aquaculture. Around 40 genera and more than 380 species of cymothoid are recognised. Species of the Cymothoidae are generally found in warmer waters and rarely in the cool and cold climates.
Protozoa are a polyphyletic group of single-celled eukaryotes, either free-living or parasitic, that feed on organic matter such as other microorganisms or organic debris. Historically, protozoans were regarded as "one-celled animals".
Frontonia is a genus of free-living unicellular ciliate protists, belonging to the order Peniculida. As Peniculids, the Frontonia are closely related to members of the genus Paramecium. However, whereas Paramecia are mainly bacterivores, Frontonia are capable of ingesting large prey such as diatoms, filamentous algae, testate amoebas, and even, in some circumstances, members of their own species. In bacteria-rich saprobic conditions, Frontonia leucas can live as a facultative bacterivore.
Cheilotoma is a genus of beetles in the subfamily Cryptocephalinae of the leaf beetles family.
Dimarcusidae is a family of triclads found mostly in freshwater habitats of caves, although at least one species, Rhodax evelinae, occurs in surface waters. Currently the family contains only seven species distributed in five genera, although the total number of species is thought to be much higher.
Mallosia, described by Étienne Mulsant in 1847, is a genus of longhorn beetles of the subfamily Lamiinae, tribe Saperdini. It is distributed in the Palearctic, from Greece to Caucasus and Iran.
Hozbeka is a monotypic moth genus in the family Oecophoridae erected by Hüseyin Özdikmen in 2009. Its only species, Hozbeka anomala, was described by John Frederick Gates Clarke in 1978. It is found in Chile.
Dorcadion glabrofasciatum is a species of beetle in the family Cerambycidae. It was described by Karl Daniel in 1900. It is known from Turkey.
Condylostoma is a genus of unicellular ciliate protists, belonging to the class Heterotrichea.
Cothurnia is a genus of freshwater and marine peritrichs in the family Vaginicolidae. It is characterised by living in a transparent tubular lorica. During the feeding or vegetative phase of its life cycle, Cothurnia attaches to submerged surfaces through a short stalk — mostly on the surfaces of fishes, crustaceans and aquatic plants. It is commonly studied for its epibiotic relationship with the host that it is attached to.
Eminella is a monotypic genus of Argentinian running crab spiders containing the single species, Eminella ctenops. It was first described by H. Özdikmen in 2007, and is only found in Argentina.
Neodietrichia is a monotypic genus of North American dwarf spiders containing the single species, Neodietrichia hesperia. It was first described by H. Özdikmen in 2008, and has only been found in Canada and the United States.
Chileana is a genus of soil centipedes in the clade Linotaeniidae and family Geophilidae found in southern Chile. This genus currently includes only one species, C. araucanensis. Females of this species are about 30mm long, with a pale yellow body and a red head; bearing 12–15 pleural pores; long, tapering antennae with sparse basal sections and rather hairy distal sections; and a labrum with four median tubercles bearing a few cilia on the sides. Males have 10 pleural pores, thick ultimate legs armed with claws, and 43 leg pairs.
Briggsus is a genus of armoured harvestmen in the family Cladonychiidae. There are about five described species in Briggsus, found in the coastal forests of Oregon and Washington.
Marina Dmitrievna Zerova was a Ukrainian entomologist. Several insects have been named after her. She became Doctor of Biological Sciences (1980), Professor (1989) and Honored Worker of Science and Technology of Ukraine (2003). In 1981 she was awarded the Award of the National Academy of Sciences of Ukraine named after DK Zabolotny.
Kirkayakidae is a family of millipedes belonging to the order Chordeumatida. This family was formerly known as Altajellidae. Adult millipedes in this family have 28 segments rather than the 30 segments usually found in chordeumatidans.
Octactis is a genus of silicoflagellates, marine photosynthetic unicellular protists that take the form of either flagellates or axopodial amoebae. Described by Josef Schiller in 1925, Octactis contains various species of marine phytoplankton, some of them responsible for algal blooms that are toxic to fish.
