Revisão sistemática de autotomia em larvas de Odonata: um método de defesa com alto custo na sobrevivência

Abstract

Autotomy is a phenomenon of pre-determined biological rupture, where an animal detaches a part of the body, with the function of defending itself. Thus, the autotomy occurs in response to a perceived threat, acting as a proximal defense strategy for the individual. Thus, the autotomy has evolved at different rates, as in the order Odonata. However, there are consequences caused by such a process, such as loss of mobility and additional energy expenditure. With that, this study carried out a systematic review of studies related to autotomy of caudal lamellae in nymphs of the order Odonata, in order to discuss what knowledge they have of this process, within the taxonomic group (Odonata) and understand what are the possible costs of this defensive process. This review will show that the autotomy of the caudal appendages is beneficial for the individual, as it allows survival, even with the high costs it represents.
