This is greatly overstated, though, since the similarity was more structural than anything else. In fact, Volta is just as well known for the much more important demonstration that biological processes were not a pre-condition for electrical generation. From his wikipedia page:
Luigi Galvani, an Italian physicist, discovered something he named, "animal electricity" when two different metals were connected in series with a frog's leg and to one another. Volta realised that the frog's leg served as both a conductor of electricity (what we would now call an electrolyte) and as a detector of electricity. He also understood that the frog's legs were irrelevant to the electric current, which was caused by the two differing metals
