死亡，也被称为死亡的伪装，我们认为更恰当的是，强直性不动（TI）是一个未被报道，但迷人的反捕食者的策略，通过不同的猎物在捕食序列的后期，并经常以下的捕食者的身体接触。TI被认为可以抑制捕食者的进一步攻击，并减少捕食者进一步制服猎物的感知需求。这种行为可能存在于比目前描述的更多的分类群中，但即使在研究充分的群体中，由于一些实际和伦理原因，精确的分类分布也不清楚。在这里，我们综合了调查TI的形式，功能，进化和生态成本和效益的关键研究。这篇评论还考虑了潜在的进化影响，某些捕食者类型的战略发展中的猎物，和其他非防御性的情况下，TI已被建议发生。我们认为，有必要在科学文献中更好地理解TI，并概述潜在的有利可图的研究途径。未来在野外使用技术应该会为这一研究领域带来有益的发展。反掠夺防御对行为生态学的许多方面都至关重要。致死症（通常称为假死）长期以来一直是一种未被充分认识的防御手段，尽管在分类学和生态学上广泛存在。我们开始提供急需的澄清术语和定义。我们展示了如何在最近的文献中明显不同的意见，可以通过将行为的成本效益框架内的替代行为的选择，以及如何不同的生态方面的影响成本和效益进行合成。扩展这一点，我们提供了新的见解，为什么致死病的进化可以理解的捕食者和猎物之间的共同进化。我们提供了进一步的新的假设，并讨论了如何测试这些假设，重点是新兴技术如何在发展我们对自由生活的动物死亡的理解方面发挥巨大作用。
Thanatosis—also known as death-feigning and, we argue more appropriately, tonic immobility (TI)—is an under-reported but fascinating anti-predator strategy adopted by diverse prey late on in the predation sequence, and frequently following physical contact by the predator. TI is thought to inhibit further attack by predators and reduce the perceived need of the predator to subdue prey further. The behaviour is probably present in more taxa than is currently described, but even within well-studied groups the precise taxonomic distribution is unclear for a number of practical and ethical reasons. Here we synthesise the key studies investigating the form, function, evolutionary and ecological costs and benefits of TI. This review also considers the potential evolutionary influence of certain predator types in the development of the strategy in prey, and the other non-defensive contexts in which TI has been suggested to occur. We believe that there is a need for TI to be better appreciated in the scientific literature and outline potentially profitable avenues for investigation. Future use of technology in the wild should yield useful developments for this field of study. Anti-predatory defences are crucial to many aspects of behavioural ecology. Thanatosis (often called death-feigning) has long been an under-appreciated defence, despite being taxonomically and ecologically widespread. We begin by providing much-needed clarification on both terminology and definition. We demonstrate how apparently disparate observations in the recent literature can be synthesised through placing the behaviour within a cost-benefit framework in comparison to alternative behavioural choices, and how aspects of the ecology differentially affect costs and benefits. Extending this, we provide novel insights into why the evolution of thanatosis can be understood in terms of coevolution between predators and prey. We offer further novel hypotheses, and discuss how these can be tested, focussing on how emerging technologies can be of great use in developing our understanding of thanatosis in free-living animals.
