Cavalier-Smith , 1991

The alveolata form a taxon of unicellular eukaryotes . They include the dinoflagellates (Dinoflagellata), the Apicomplexa and the ciliate (Ciliophora). All three tribes contain complex single-celled creatures.

features

The name-giving feature of the individual sub-taxa are differently designed flat vacuoles under the cell membrane (pellicula), so-called alveoli , which have been lost again in some species. The function of these alveoli is not always known. In the case of dinoflagellates, these vacuoles are filled with cellulose in many species and are called theca.

Further features are tubular or bottle-like tapering cristae in the mitochondria .

The group presumably emerged from a Perkinsus- like representative 1.2 billion years ago .

Systematics

Adl et al. divide the alveolata into the following groups:

• Dinoflagellates (Dinoflagellata)
• Apicomplexa
• Ciliates (ciliophora)
• Protalveolata
  • Perkinsidae
  • Chromerida
  • Colpodellida
  • Syndiniales
  • Oxyrrhis
• incertae sedis within the alveolata:
  • Colponema
  • Ellobiopsidae
