Representative stress–strain curves from tensile tests on (a) natural and decalcified wool fibres, and (b) natural and decalcified sei, (c) humpback and (d) minke whale baleen bristles. Note how decalcification leads to a decrease in the initial modulus and yield stress of the two most highly calcified baleen types (humpback and sei), whereas decalcification has little effect on these values for minke baleen and wool. Black lines, natural; grey lines, decalcified.
