Although most otoliths of teleost fishes contain aragonite, a detailed survey of the otoliths of serveral species confirms that other crystalline forms of calcium carbonate occur. Otoliths of Hoplostethus atlanticus, Pagrus major, Macruronus novaezelandiae, Merluccius australis, Congiopodus coriaceus, Kathetostoma giganteum, Argentina elongata, Rhomobosolea tapirina, Neophrynichthys latus, Coelorinchus aspercephalus, Paranothothenia microlepidota, and Gonorhynchus gonorhynchus contained the aragonite, calcite, and vaterite morphs of calcium carbonate in varying proportions. Aragonitic otoliths of Allocyttus niger, Hoplostethus altlanticus, and Pagrus major contained sequences of calcite-like crystals. The surface of the vateritic otolith of Acipenser brevirostrum is shown in detail. Three classes of information are stored in the crystalline structure of the otolith: shape conservation, coexisting crystal morphs, and consecutive changes in crystal morph. Analysis of this crystalline information supports the hypothesis of control of growth of the otolith by proteins from the sensory epithelium or macula. Protein variation involved may be genetic in origin, or non-genetic arising from "stuttering" of the translation process. Proteins extracted from vateric and aragonitic morphs of the otolith of Macruronus novaezelandiae showed differences in infared absorption spectra that were consistent with two different amino acid sequences. © 1993 Wiley-Liss, Inc.
虽然大多数硬骨鱼类的耳石含有文石，但对几种鱼类耳石的详细调查证实，碳酸钙的其他晶体形式也存在。大西洋胸棘鲷、真鲷、新西兰无须鳕、澳大利亚无须鳕、革质异康吉鳗、大口突吻鳕、长蛇鲻、塔氏斜棘鲆、宽体新蟾鱼、粗糙头腔吻鳕、小鳞副南极鱼和长吻丝鳗的耳石含有不同比例的碳酸钙文石、方解石和球霰石形态。黑异鳞鲀、大西洋胸棘鲷和真鲷的文石耳石含有类方解石晶体序列。详细展示了短吻鲟球霰石耳石的表面。耳石的晶体结构中存储了三类信息：形状守恒、共存晶体形态以及晶体形态的连续变化。对这种晶体信息的分析支持了耳石生长受感觉上皮或黄斑蛋白质控制的假说。所涉及的蛋白质变异可能源于遗传，也可能源于翻译过程的“口吃”导致的非遗传变异。从新西兰无须鳕耳石的球霰石和文石形态中提取的蛋白质在红外吸收光谱上显示出差异，这与两种不同的氨基酸序列一致。© 1993威利 - 利斯公司。
