For instance, is the skeletal muscle of an elephant made of the same balance of fibers and cells as the skeletal muscle of a hippopotamus?
I recognize that slow- and fast-twitch muscles are a thing, and that which animals have which vary. I also recognize that different animals might have different numbers of mitochondria per muscle cell, and that there's a difference between skeletal, smooth, and cardiac muscle, but am still conflicted on one thing would it be accurate to claim that the mechanical properties, density, and the like of all types of animal skeletal muscle are the same?
If you happen to have a source for your answer, please supply one - it'll be useful for something I'm trying to write.
