Meanings
plural opisthokonts
- biologyAny of very many eukaryotes, including animals and fungi, whose flagellate cells (if any) propel themselves with a single posterior flagellum.
However, these characters are only sporadically found among the various opisthokont allies (described above).

Based on a single posterior flagellum (opisthokont), flattened, nondiscoid mitochondrial cristae, a chitinous exoskeleton, storage of glycogen instead of starch, lack of chloroplasts, and the code UGA for tryptophan, not chain termination, in their mitochondria, Cavalier-Smith [54] suggests a common origin of the true fungi with animalia and choanoflagellate protozoa (fig. 1).

Lehrer, Fungal Allergy and Pathogenicity, Karger Medical and Scientific Publishers, →ISBN, page 211, →ISBNAlthough the group embraces taxa that are diverse in morphology and life history, cells of undisputed opisthokonts have a single emergent flagellum which projects behind the cells while they swim. This is treated as defining the opisthokont ancestry.
