“…Cells feed on small naked amoebae and capture a prey by the ventral side of the body, remaining motionless for a short time, until food is absorbed (Nikolaev et al, 2006). Morphology of observed cells is in agreement with previous studies, but Mikrjukov and Mylnikov (1998) described larger cells (up to 40 µm in diameter in culture), while the largest cells observed in our investigation were 15 µm. This species is very easily distinguished from other flagellates because of its unusual morphology.…”

“…Also tetraflagellar, giant multi-flagellar (with up to 200 flagella), branching or horseshoe-shaped forms, developing in culture after sharp salinity decrease, have been described (Mikrjukov and Mylnikov, 1998). Cells feed on small naked amoebae and capture a prey by the ventral side of the body, remaining motionless for a short time, until food is absorbed (Nikolaev et al, 2006).…”

“…Particularly, the diversity of heterotrophic flagellates and centrohelid heliozoans of the Black Sea is poorly studied and reports on their observations are limited to a few papers (Ostroumov, 1917;Valkanov, 1940Valkanov, , 1970Moiseev, 1980;Mikrjukov and Mylnikov, 1998;Mikrjukov, 1999;Leonov, 2010;. The aims of our study were to identify species composition and investigate details of the morphology of heterotrophic flagellates and centrohelids from the Black Sea (the Southern part of the Crimea) by methods of light and electron microscopy.…”

SummarySpecies composition and morphology of heterotrophic flagellates and centrohelid heliozoa in littoral and supralittoral zones of the Black Sea in the Southern part of the Crimea were studied. Overall, 68 species of heterotrophic flagellates and 2 species of centrohelids were encountered in this survey, of which 44 species are the first records for the Black Sea. Many species are widespread and known not only from marine but also from freshwater and soil habitats. Most observed species feed on bacteria, 14 species consume other protists (heterotrophic flagellates, algae, and naked amoebae). Micrographs and morphological descriptions of 20 species

“…Outside bilaterians, MCCs are found in ctenophores (Tamm and Tamm 1988) and in sponges; although, in the latter case, each BB is associated to an accessory BB (i.e., like in a centrosome), suggesting that distinct mechanisms are used for BB assembly in these cells (Boury-Esnault et al 1999). It is worth mentioning that MCCs are also found outside of animals in phyla as diverse as plants, ciliates, or amoebozoa (Tamm et al 1975;Mikrjukov and Mylnikov 1998;Hodges et al 2010). This distribution is most likely the result of convergent evolution, however, because these phyla originate from distinct mono-or biflagellated unicellular ancestors (Adl et al 2012;Azimzadeh 2014).…”

Many animal cells assemble single cilia involved in motile and/or sensory functions. In contrast, multiciliated cells (MCCs) assemble up to 300 motile cilia that beat in a coordinate fashion to generate a directional fluid flow. In the human airways, the brain, and the oviduct, MCCs allow mucus clearance, cerebrospinal fluid circulation, and egg transportation, respectively. Impairment of MCC function leads to chronic respiratory infections and increased risks of hydrocephalus and female infertility. MCC differentiation during development or repair involves the activation of a regulatory cascade triggered by the inhibition of Notch activity in MCC progenitors. The downstream events include the simultaneous assembly of a large number of basal bodies (BBs)-from which cilia are nucleated-in the cytoplasm of the differentiating MCCs, their migration and docking at the plasma membrane associated to an important remodeling of the actin cytoskeleton, and the assembly and polarization of motile cilia. The direction of ciliary beating is coordinated both within cells and at the tissue level by a combination of planar polarity cues affecting BB position and hydrodynamic forces that are both generated and sensed by the cilia. Herein, we review the mechanisms controlling the specification and differentiation of MCCs and BB assembly and organization at the apical surface, as well as ciliary assembly and coordination in MCCs.

The free-living heterotrophic fl agellates are phylogenetically very diverse, and their phylogenetic diversity is nearly equal to that of all eukaryotes. They constitute the microbial loop together with bacteria and other protists, and play an indispensable and important role in aquatic ecosystems. However, their diversity has not been fully understood. In addition, recent environmental DNA studies suggest that there are many unidentifi ed heterotrophic fl agellate lineages in nature. This chapter describes the current knowledge on the diversity, biology and ecology of various groups of free-living heterotrophic fl agellates.
