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.

    $\begingroup$ I recall Comparative Biomechanics by Vogel stating the power density is roughly similar. Similar enough to group together and make comparisons with groups of man made actuators. $\endgroup$

    $\begingroup$ This doesn't appear to be answerable by anything other than opinion — can you please specify your criteria for "similar". $\endgroup$

  • $\begingroup$ @tyersome Having similar physical densities, compressive and tensile strengths, Young's moduli, extensibilities, and so on and so forth - essentially, properties of the muscle in regards to materials science. $\endgroup$
