Sawsharks (Order: Pristiophoriformes, Family: Pristiophoridae) are a highly distinctive group of sharks, characterized by a tapering saw‐like rostrum with a pair of elongate barbels on the ventral surface. Their unusual characteristics should attract attention; however, very few studies have been dedicated to sawsharks. As a result, our understanding of their biology and ecology is limited. However, information on aspects of their biology and ecology can be found in studies not directly focussing on sawsharks. This review provides a synthesis of information pertaining to the 10 recognized sawshark species following a comprehensive search of the scientific literature. We cover their distributions, habitat utilization, life histories, reproduction, trophic dynamics and sensory biology. Current knowledge on their unique rostral structures, the evolutionary history of pristiophorids, taxonomy, behaviour and threats to sawshark populations are also reviewed. This compilation serves as a foundation for sawshark researchers and highlights key knowledge gaps in this unique group of elasmobranchs, thereby beginning the sawshark redemption.

锯鲨的赎回：锯鲨的当前知识和未来发展方向

锯齿鲨（顺序：Pristiophoriformes，家族：Pristiophoridae）是一组非常独特的鲨鱼，其特征是呈锥形的锯状讲台，腹面带有一对细长的须。它们的不寻常特征应引起注意；然而，很少有关于锯齿鲨的研究。结果，我们对它们的生物学和生态学的理解是有限的。然而，有关其生物学和生态学方面的信息可以在不直接关注锯齿鲨的研究中找到。在全面检索科学文献之后，本综述提供了与10个公认的锯齿鲨物种有关的信息的综合。我们涵盖了它们的分布，栖息地利用，生活史，繁殖，营养动力学和感觉生物学。有关其独特的延髓结构的最新知识，还回顾了节肢动物的进化史，分类学，行为和对锯齿鲨种群的威胁。该汇编为锯齿鲨研究人员奠定了基础，并突出了这一独特的弹性分支中的关键知识差距，从而开始了锯齿鲨的赎回。
