Taxonomy • ?Brachionus polyacanthus Ehrenberg after Bailey (1851); Brachionus leydigii Cohn after Sharma & Sharma (2015) (=B. r. f. rhenanus); B. mirabilis Daday after Thomasson (1971, part.: pl.XX fig.3);
not Brachionus quadridentatus Hermann after Althaus (1957 partim:fig.6d) [=B. urceolaris Müller?]; Leentvaar (1975) [Ref.18194] [=Platyias sp.].
• Hermann (1783:47) in his description of Brachionus quadridentatus refers to Baker's (1753) figures of "Wheel animals having a shell": "Dieses Thierchen ist schon bei Baker Tab XII. fig.11-13 nicht übel abgebildet". Apparently Hermann was unaware that some years earlier Pallas (1766) based his description of Brachionus capsuliflorus on exactly the same figures. Notwithstanding that the 'Principle of Priority' (ICZN Art.23) requires that the oldest available name of a taxon be the valid name, the younger name Brachionus quadridentatus Hermann is in prevailing usage and, for the sake of nomenclatural stability, receives priority over Pallas' earlier established name.
• Polymorphic species with a number of sub- and infrasubspecific taxa of uncertain taxonomic status. Probably represents a complex of cryptic species with narrower geographic ranges and/or ecological tolerances.
• By using sequences of mitochondrial COI and nuclear 18S genes, Garcia-Morales & Dominguez-Dominguez (2019) explored the genetic diversity among some Mexican populations of B. quadridentatus, including B. qu. quadridentatus Hermann, B. qu. f. brevispinus Ehrenberg, and B. qu. cluniorbicularis Skorikov. The authors concluded, that at least three putative species are present within the B. quadridentatus complex. [details]

Environment saltwater occurrences include inland saline waters. [details]

Grammatical gender Gender agreement: yes; name type: adjective [details]

Habitat Bottom sediments (shallow littoral); Eichhornia crassipes (water hyazinth), interrhizon; Littoral microhabitats; Littoral vegetation (Macrophytes and partly emersed terrestrial plants); Macrophytes (Ceratophyllum, Myriophyllum); Macrophytes (Elodea); Macrophytes (Myriophyllum), and littoral vegetation; Macrophytes (Myriophyllum, Potamogeton); Macrophytes (Potamogeton pectinatus?); Macrophytes (Utricularia); Macrophytes (Utricularia, Nymphaea); Open water; Open water (littoral and offshore); Open water (offshore); Open water (tychoplanktonic); Water lenses (Lemna sp.) [details]

Taxonomy • ?Brachionus polyacanthus Ehrenberg after Bailey (1851); Brachionus leydigii Cohn after Sharma & Sharma (2015) (=B. r. f. rhenanus); B. mirabilis Daday after Thomasson (1971, part.: pl.XX fig.3);
not Brachionus quadridentatus Hermann after Althaus (1957 partim:fig.6d) [=B. urceolaris Müller?]; Leentvaar (1975) [Ref.18194] [=Platyias sp.].
• Hermann (1783:47) in his description of Brachionus quadridentatus refers to Baker's (1753) figures of "Wheel animals having a shell": "Dieses Thierchen ist schon bei Baker Tab XII. fig.11-13 nicht übel abgebildet". Apparently Hermann was unaware that some years earlier Pallas (1766) based his description of Brachionus capsuliflorus on exactly the same figures. Notwithstanding that the 'Principle of Priority' (ICZN Art.23) requires that the oldest available name of a taxon be the valid name, the younger name Brachionus quadridentatus Hermann is in prevailing usage and, for the sake of nomenclatural stability, receives priority over Pallas' earlier established name.
• Polymorphic species with a number of sub- and infrasubspecific taxa of uncertain taxonomic status. Probably represents a complex of cryptic species with narrower geographic ranges and/or ecological tolerances.
• By using sequences of mitochondrial COI and nuclear 18S genes, Garcia-Morales & Dominguez-Dominguez (2019) explored the genetic diversity among some Mexican populations of B. quadridentatus, including B. qu. quadridentatus Hermann, B. qu. f. brevispinus Ehrenberg, and B. qu. cluniorbicularis Skorikov. The authors concluded, that at least three putative species are present within the B. quadridentatus complex. [details]
