The heraldic rotifer ( Brachionus calyciflorus ) is a species from the genus Brachionus from the tribe of the rotifers (Rotatoria). B. calcyflorus shows cyclic parthenogenesis (sexual and asexual reproduction), a transition to obligatory parthenogenesis is possible. Due to this property, the rotifer is also used in biological research.
morphology
The foot is long and flexible. There are four spines anteriorly, 0–2 spines posteriorly. Males are smaller than females. Subspecies are e.g. B. B. c. var. pala and B. c. var. dorcas .
ecology
Brachionus calyciflorus is widespread in planktonic lakes and smaller bodies of water.
