Interstitial connective tissue (perimysium).
PTAH histochemical stain. (A) The red connective tissue was present in the interstitial spaces between muscle fibers and was observed in the areas intramuscular nerves (plus). Neonate male of striped dolphin (Stenella coeruleoalba). 100× magnification. (B) Variable fatty infiltration of the interstitial connective tissue was observed within the deep-diving species in our study. Juvenil female of Cuvier’s beaked whale (Ziphius cavirostris). 40× magnification.
