Background As dominant components of planktonic microeukaryotes, the tintinnine ciliates act as a trophic link between microbial food web and traditional planktonic food chain in aquatic ecosystems. However, traditionally the taxonomy and systematics

In the present study the morphology and ciliary pattern of three marine tintinnid ciliates, namely Tintinnopsis tocantinensis Kofoid and Campbell, 1929, Tintinnopsis radix (Imhof, 1886) Brandt, 1907, and Tintinnopsis cylindrica Daday, 1887, isolated from

Many microbial taxa in the marine plankton appear super-saturated in species richness. Here, we provide a partial explanation by analyzing how species are organized, species packing, in terms of both taxonomy and morphology. We focused on a well-studied

An examination of plankton samples collected from the inshore and offshore waters in the vacancy of Hurghada area in the Egyptian Red Sea coast revealed the presence of a diverse community of planktonic tintinnids (Protozoa). Ninety two tintinnid species

Tintinnids are loricated ciliates found in coastal and oceanic waters that play a key role in the transference of energy to highest trophic levels. The purpose of this article is intended to integrate the available information about the taxonomy and distribution
