Description |
|---|---|---|
Buccal membranelles |
The buccal membranelles are entirely situated in the buccal cavity and constitute the posterior portion of the oral primordium in early dividers. Note that some authors do not differentiate... |
|
Capsules |
Capsules are probably extrusive organelles that are attached to the cell membrane of cytoplasmic extensions, such as, accessory combs, striae, and tentaculoids. They are subspherical, 200-600 nm... |
|
Carnivory |
Predation |
The eating and/or digesting of animal biomass. |
Chloroplast (compound) |
Taxonomy |
The compound chloroplast, in which all pyrenoids are concentrated centrally in the cell, was originally thought to be a rare type of chloroplast in dinoflagellates. However, in recent years this... |
Cingular plates |
Taxonomy |
In thecate dinoflagellates, the plate that make up the cingulum (designated with a 'c'). |
Cingulum |
Taxonomy |
In dinoflagellate, this structure is usually a furrow (girdle) encircling the cell once or several times, and it can be displaced. In thecated species, the cingulum is made up of plates. This... |
Collar membranelles |
The collar membranelles form a closed zone on the peristomial rim and constitute the anterior portion of the oral primordium in early dividers. They have larger polykinetids and longer cilia than... |
|
Concave |
Taxonomy |
Hollowed or rounded inward resembling the inside of a bowl. |
Conoid |
Parasitology, Taxonomy |
A cone-shaped cytoskeletal structure that functions as scaffolding for rhoptries of the apical complex. Conoids comprise microtubules and can be completely closed, as in apicomplexans, or open-... |
Convex |
Taxonomy |
Curved or rounded resembling the exterior of a sphere or circle. |
Cosmopolitan |
Ecology |
Globally distributed. |
Dense granules |
Parasitology, Taxonomy | |
Density (of infection) |
Parasitology |
Number of individuals of a particular parasite species per unit area, volume, or weight of infected host tissue or organ. The units should always be clearly specified. |
Disjunction |
Ecology |
The spatial separation of populations due to dispersal or vicariance. |
Dispersal |
Ecology |
The flow of organisms from one location to another, either passively (for example, blown by wind) or actively (for example, flight). |
Dorsal |
Taxonomy |
Of or relating to the back side of an organism. |
Dorsal kinety |
The dorsal kinety is separate from the right and left ciliary field between which it is situated dorsally. It is the longest kinety, usually extending from the membranellar zone to the base of the... |
|
Dorsoventral |
Taxonomy |
Extending along the axis joining the dorsal and ventral sides. |
Ejectisome |
Parasitology, Predation, Taxonomy | |
Endemic |
Ecology |
Restricted to specific geographic locations. |
