The fiber type profiles of M. gastrocnemius of five species in Order Carnivora were estimated histochemically. The muscle of all these five species contained two types of fibers which differed from each other in adenosine triphosphatase (ATPase) activity after preincubation at pH 4.2 (Vulpes vulpes), 4.3 (Martes melampus), 4.2-4.4 (Nyctereutes procyonoides) and 4.3-4.4 (Meles meles, Mustela itatsi) and in succinate dehydrogenase (SDH) activity. Based on the ratio of the number of muscle fibers with a high APTase activity to that with a low activity after incubation at a definite acidic pH range, the muscles in Nyctereutes procyonoides and Vulpes vulpes differed from those in the other three species. The ratio was higher in the former than in the latter. It was found also that among these species, the muscle in Martes malampus had the highest proportion of the fibers with a strong SDH activity.
