Morphology
provided by Marine Rotifera LifeDesk
Brachionus falcatus is not highly variable except for slight growth in the anterior and posterior spines. Occipital margin with six spines; intermediates much longer and curved ventrally; medians and laterals shorter and of almost equal length. Posterior spines long, incurved and with widely separated bases. The anterior and posterior spines vary considerably. A form with very spines was found in large numbers from a river. This form with shorter spines may be a modification for running water existence since longer spines tend to entangle easily. Lorica composed of a dorsal and ventral plate and compressed dorso-ventrally. Anterior dorsal margin with six spines. The intermediates are much longer than the laterals and curved laterally outwards. Median spines equal to the lateral spines.
