The incorporation and distribution of the model intrinsically disordered Starmaker‐like (Stm‐l) protein, which is active in fish otoliths biomineralization, within calcium carbonate crystals was studied in vitro. The Stm‐l promotes calcium carbonate nucleation and anisotropic tailoring of crystal morphology. Intracrystalline incorporation of protein results in shrinkage of the crystal lattice volume. The ring pattern, composed of a protein‐enriched region flanked by protein‐depleted regions, is a result of both the Ostwald‐like ripening process and intrinsic properties of Stm‐l, and bears some analogy to the daily growth layers of the otolith.
