On Growth and Form published in 1917, the biologist D’Arcy Thompson (1860 – 1948) laid the foundations of what is now called bio-mathematics.
This works especially well with fish. It’s easy to turn many fish into one another using this mathematical “paper stretching and skewing” method.
For a more known example of the power of “paper stretching and skewing”, see Einstein [although he wasn’t the first to come up with warping space but nobody took it as far as he did]
