The mineralized cuticle of the mantis shrimps Squilla Mantis which serve as natural hammers, spears and armors, have attracted research attention from various fields due to its amazing mechanical properties which were studied from evolutionary and ecological points of view. Here we aimed to valorize the astonishing mantis shrimp shell waste resulted from fishery and seafood industry as valuable biogenic composite derived from nature, potentially re-usable for novel, smart materials or added-value by-products, aspect which was not deeply considered before. Employing multi-laser Raman spectroscopy and imaging, supported by x-ray diffraction and high-resolution electron microscopy, we discover that the peripheral segments anatomically known as claws and telson, featured completely different composition and morphology, suggesting different applicability. The claw presents a bulk Mg-CaCO₃ structure reinforced with fluorapatite coating, while the carotenoid-rich telson presents a porous and anisotropic structure of an amorphous mixture of CaCO₃ and CaPO₄ in gradient deposition on the chitin-protein scaffold.Resonance Raman spectroscopy showed concentrated pools of astaxanthin carotenoid within the bright red spots visible on telson, Based on our findings, we discuss this material’s potential for selective applicability, as a natural source of phosphate-carbonate minerals, antioxidants, biofertilizer, pollutant adsorbent, valuable material for regenerative medicine or even as a cell culture substrate. Knowledge-based approach on this bio-template is the basis for smart recycling of such fishery waste for sustainable development, by opening channels for blue bioeconomy avenue.

螳螂矿化角质层虾蛄螳螂作为天然锤子，长矛和盔甲的材料，由于其惊人的机械性能而受到了进化和生态学的研究，因而受到了各个领域的研究关注。在这里，我们的目标是使渔业和海鲜业产生的惊人虾man废料价值不菲，是源自自然的有价值的生物合成复合物，可潜在地用于新颖，智能的材料或增值副产品，而这在以前从未被深思熟虑。利用多激光拉曼光谱和成像技术，在X射线衍射和高分辨率电子显微镜的支持下，我们发现在解剖学上被称为爪子和telson的外周节段具有完全不同的组成和形态，表明适用性不同。爪子呈块状Mg-CaCO氟磷灰石涂层增强了₃结构，而富含类胡萝卜素的telson呈现了CaCO ₃和CaPO ₄的非晶混合物的多孔各向异性结构共振拉曼光谱显示，虾青素类胡萝卜素集中在telson可见的红色斑点内，根据我们的发现，我们讨论了这种材料作为磷酸碳酸盐的天然来源的选择性应用潜力。矿物质，抗氧化剂，生物肥料，污染物吸附剂，可再生医学的有价值材料，甚至可作为细胞培养基质。通过开放蓝色生物经济途径的渠道，在此生物模板上基于知识的方法是为此类渔业废物进行智能回收以实现可持续发展的基础。
