By combining phalloidin‐TRITC staining with confocal scanning laser microscopy (CSLM), the pattern of the musculature in two species of Rotifera, Euchlanis dilatata unisetata and Brachionus quadridentatus is revealed. The same general muscle pattern prevails in both species. The major components of the body wall musculature are: 1. retractor muscles (5 pairs in E. dilatata unisetata and 3 pairs in B. quadridentatus ); 2. Two pairs of dorso‐ventral muscles; 3. Two pairs of perpendicular muscles (in E. dilatata unisetata ); 4. retractors of the corona (median, lateral and ventral); 5. Foot retractors. In addition, three pairs of cutaneo‐visceral muscles and visceral muscles (including mastax muscles) are described. The sphincter of the corona was found only in B. quadridentatus . The high degree of muscle differentiation points to a high level of development of rotifer muscular system.
