The Warnowiaceae are a family of athecate dinoflagellates (a diverse group of unicellular eukaryotes).Members of the family are known as warnowiids.The family is best known for a light-sensitive subcellular structure known as the ocelloid, a highly complex arrangement of organelles with a structure directly analogous to the eyes of multicellular organisms.
Mixotrophic dinoflagellates have the ability to thrive in changing ocean environments, resulting in shifts in red tide phenomenon and paralytic shellfish poisoning. [6] It is unknown as to how many species of dinoflagellates have mixotrophic capabilities, as this is a relatively new feeding-mechanism discovery.
Amphidinium is a genus of dinoflagellates. The type for the genus is Amphidinium operculatum Claparède & Lachmann. The genus includes the species Amphidinium carterae which is used as a model organism. [1] As dinoflagellates, Amphidinium spp. have chloroplasts. The Amphidinium chloroplast genome is unusual in not having a single contiguous ...
Alexandrium is a genus of dinoflagellates. It contains some of the dinoflagellate species most harmful to humans, because it produces toxic harmful algal blooms (HAB) that cause paralytic shellfish poisoning (PSP) in humans.
Karlodinium veneficum is a species of dinoflagellates belonging to the family Kareniaceae. [1] This species is predominantly inhabiting aquatic environments, particularly in temperate coastal regions. Karlodinium veneficum genome sizes have been reported as ~20 pg/cell [2] and 4 pg/cell. [3]
Peridinium is a genus of motile, marine and freshwater dinoflagellates. [1] [2] Their morphology is considered typical of the armoured dinoflagellates, and their form is commonly used in diagrams of a dinoflagellate's structure. [1] [3] Peridinium can range from 30 to 70 μm in diameter, and has very thick thecal plates. [1] [3]
An amateur fossil hunter has uncovered a piece of animal vomit which dates back 66 million years on a beach in Denmark.
The dinoflagellete type of luciferin used in this reaction is one of the four common types of luciferin found in the marine environment, [11] and the genome of P. fusiformis contains shared common origin with other dinoflagellates that contain the luciferase enzyme. [5] In the laboratory, two different types bioluminescent flashes have been ...
