  2. Peranema - Wikipedia

    en.wikipedia.org/wiki/Peranema

    Peranema. Peranema's basic anatomy is that of a typical euglenid. The cell is spindle or cigar-shaped, somewhat pointed at the anterior end. It has a pellicle with parallel finely-ridged proteinaceous strips underlain by microtubules arranged in a helical fashion around the body. With this type of pellicle, which is shared by many euglenids ...

    Peranema sp. (Heteronematales) The first attempt at classifying euglenids was done by Ehrenberg in 1830, when he described the genus Euglena and placed it in the Polygastrica of family Astasiae, containing other creatures of variable body shape and lacking pseudopods or lorica.

    In addition, like some other euglenids, their cells exhibit a certain movement known as metaboly or 'euglenid motion' characterized by extreme flexibility and malleability. [ 2 ] Evolution

    In 1997, a morphological and molecular study of the Euglenozoa put Euglena gracilis in close kinship with the species Khawkinea quartana, with Peranema trichophorum basal to both. [36] Two years later, a molecular analysis showed that E. gracilis was, in fact, more closely related to Astasia longa than to certain other species recognized as ...

    Euglena gracilis. A morphological and molecular study of the Euglenozoa put E. gracilis in close kinship with the species Khawkinea quartana, with Peranema trichophorum basal to both, [4] although a later molecular analysis showed that E. gracilis was more closely related to Astasia longa than to certain other species recognized as Euglena.

    Three types of excavate cells. Top: Jakobida, 1-nucleus, 2-anterior flagellum, 3-ventral/posterior flagellum, 4-ventral feeding groove.Middle: Euglenozoa, 1-nucleus, 2-flagellar pocket/reservoir, 3-dorsal/anterior flagellum, 4-ventral/posterior flagellum, 5-cytostome/feeding apparatus.

  8. Spirocuta - Wikipedia

    en.wikipedia.org/wiki/Spirocuta

    Spirocuta (from Latin spira 'coil, spire' and cutis 'skin') is a clade of euglenids, single-celled eukaryotes or protists belonging to the phylum Euglenozoa.They are distinguished from other euglenids by active deformation of their cell shape, a process called euglenid motion or metaboly.

  9. Euglenales - Wikipedia

    en.wikipedia.org/wiki/Euglenales

    Euglenales consists mostly of freshwater organisms, in contrast to its sister Eutreptiales which is generally marine. Cells have two flagella, but only one is emergent; the other is very short and does not emerge from the cell, so cells appear to have only one flagellum. [3]
