Katodinium is a genus of dinoflagellates belonging to the family Tovelliaceae. [1]
The genus was first described by Fott in 1957. [1]
The Noctilucales are an order of marine dinoflagellates. They differ from most others in that the mature cell is diploid and its nucleus does not show a dinokaryotic organization. They show gametic meiosis.
Cryptomonas is the name-giving genus of the Cryptomonads established by German biologist Christian Gottfried Ehrenberg in 1831. The algae are common in freshwater habitats and brackish water worldwide and often form blooms in greater depths of lakes. The cells are usually brownish or greenish in color and are characteristic of having a slit-like furrow at the anterior. They are not known to produce any toxins. They are used to feed small zooplankton, which is the food source for small fish in fish farms. Many species of Cryptomonas can only be identified by DNA sequencing. Cryptomonas can be found in several marine ecosystems in Australia and South Korea.
The Globigerinina is a suborder of foraminiferans that are found as marine plankton. They produce hyaline calcareous tests, and are known as fossils from the Jurassic period onwards. The group has included more than 100 genera and over 400 species, of which about 30 species are extant. One of the most important genera is Globigerina; vast areas of the ocean floor are covered with Globigerina ooze, dominated by the shells of planktonic forms.
The Syndiniales are an order of early branching dinoflagellates, found as parasites of crustaceans, fish, algae, cnidarians, and protists. The trophic form is often multinucleate, and ultimately divides to form motile spores, which have two flagella in typical dinoflagellate arrangement. They lack a theca and chloroplasts, and unlike all other orders, the nucleus is never a dinokaryon. A well-studied example is Amoebophrya, which is a parasite of other dinoflagellates and may play a part in ending red tides. Several MALV groups have been assigned to Syndiniales; recent studies, however, show paraphyly of MALVs suggesting that only those groups that branch as sister to dinokaryotes belong to Syndiniales.
Chlamydomonadaceae is a family of algae within the order Chlamydomonadales. Traditionally, it has been defined as containing single-celled flagellates with a cell wall.
Dinophyceae is a class of dinoflagellates.
Abathomphalus is a genus of foraminifera included in the Globotruncanid family.
Hedbergella is an extinct genus of planktonic foraminifera from the Cretaceous, described by Loeblich and Tappan, 1961, as:
Test free, trochospiral, biconvex, umbilicate, periphery rounded with no indication of keel or poreless margin; chambers globular to ovate; sutures depressed, radial, straight or curved; wall calcareous, finely perforate, radial in structure, surface smooth to hispid or rugose; aperture an interiomarginal, extraumbilical-umbilical arch commonly bordered above by a narrow lip or spatulate flap, ... Includes species otherwise similar to Praeglobotruncana but which lack a keel or poreless margin, hence is regarded as a separate genus rather than as a subgenus of Praeglobotruncana as by Banner and Blow (1959).
Spirulina agilis is a freshwater cyanobacterium from the genus Spirulina.
Helen Niña Tappan Loeblich was an American micropaleontologist who was a professor of geology at the University of California, Los Angeles, a United States Geological Survey (USGS) biostratigrapher, and a scientific illustrator whose micropaleontology specialty was research on Cretaceous foraminifera.
Alfred R. Loeblich Jr was an American micropaleontologist. He was married to Helen Niña Tappan Loeblich and the two co-authored a number of important works on the Foraminifera and related organisms.
Ceratoperidinium is a genus of dinoflagellates in the order Gymnodiniales. The genus contains two species. It was first created in 1969 by Margalef, with Ceratoperidinium yeye as the type species. However, because it was not correctly described it was considered invalid, as was C. yeye. In 1980, Lobelich III described the genus as Ceratoperidinium Margalef ex Loeblich III, renaming C. yeye as C. margalefii. In 2014, Gyrodinium falcatum was reassigned to Ceratoperidinium based on genetic analysis.
Tolypella is a genus of green algae belonging to the family Characeae.
Acanthoica is a genus of algae belonging to the family Rhabdosphaeraceae.
Kephyrion is a genus of algae belonging to the family Dinobryaceae.
Heterocapsa is a genus of dinoflagellates belonging to the family Heterocapsaceae.
Saturnella is a genus of algae belonging to the family Oocystaceae.
Peridiniaceae is a family of dinoflagellates belonging to the order Peridiniales.
Nicholsonella is an extinct genus of bryozoans of uncertain taxonomic placement. Its colonies can take the forms of thick branching masses or branches.
