Description

Sulcal furrow (acrobase)

Taxonomy

see Apical structure complex (ASC)

Sulcus

Taxonomy

Longitudinal area on the ventral surface of dinoflagellate-type cells that froms a pronounced furrow or depression that houses the longitudinal flagellum. In thecated species, the sulcus is made...

Synenergide nucleus

This is a peculiar aspects of some trophonts which remain uninucleate during the growth phase (described by Chatton). This large nucleus, which stops undergoing mitosis, progressively accumulates...

Tentaculoids

Tentaculoids are small, finger-like, and possibly contractile cytoplasmic extensions between the collar membranelles (Corliss 1979, Laval-Peuto and Brownlee 1986). The term was introduced by...

Theca

Taxonomy

Dinoflagellate membrane system encompassing the whole cell consisting of a complex of three to six membranes. 

Thecal plates

Taxonomy

Plates of armoured (thecated) dinoflagellate species which are composed of cellulose or polysaccharide microfibrils. Their particular size, shape and arrangement on the cell are characteristic to...

Trichocyst

Taxonomy, Predation

A cytoplasmic ejectile organelle; a minute structure that emerges through pores in the theca of armoured dinoflagellates and related lineages that releases filamentous or fibrillar threads when...

Trophocyte

Taxonomy, Life cycle, Parasitology

Trophosome

Ventral kinety

The ventral kinety is on the left side of the right ciliary field and on the right side of the oral primordium. It is the longest entirely monokinetidal ciliary row on the ventral side (Figs 1b, f...

Ventral organelles

The ventral organelles comprise a transverse (V1) and an oblique (V2) organelle, i.e., two short dikinetidal kineties posterior to the ventral collar membranelles. The term was introduced by...

Ventral pore

Taxonomy

In some dinoflagellate armored species, a ventral pore may be present at the juncture of the first apical plate (1') and an anterior intercalary or another apical plate on the epitheca. Sometimes...

Vicariance

Ecology

The separation of once continuous populations into separate populations by geological or climatic events.
