(2011). The claw closer muscle of two estuarine crab species, Cyrtograpsus angulatus and Neohelice granulata (Grapsoidea, Varunidae): histochemical fibre type composition. -Acta Zoologica (Stockholm) 00: 1-7. This study permitted the characterization of four types of muscle fibres in the claw closer muscles of Cyrtograpsus angulatus and Neohelice granulata. Succinic dehydrogenase (SDH) for mitochondria, periodic acid Schiff (PAS) for glycogen, Sudan Black B for lipids and myosin-adenosine triphosphatase (m-ATPase) preincubated at alkaline and acid pHs were used for that purpose. The mean fibre diameters, the relative areas and frequencies of each muscle fibre type were calculated. Types I and IV would be considered 'extreme' groups with type I fibres large, weak and acid/alkaline-labile m-ATPase, weak SDH, PAS and Sudan, and type IV fibres small, very strong and acid/alkaline-resistant m-ATPase, strong SDH and PAS, and moderate Sudan. Types II and III would belong to a predominant 'intermediate' group. Type IV fibres were scarce in C. angulatus but represented 25% of the total fibre population in N. granulata. In C. angulatus, the relative area occupied by type I fibres was bigger than its relative proportion, whereas in N. granulata, types I and II had similar patterns. Concluding, variations in fibre type composition in the claw closer muscles of C. angulatus and N. granulata would be linked to different habitats and feeding behaviours. © 2011 The Royal Swedish Academy of Sciences.
