Consequences of lost endings: caudal autotomy as a lens for focusing attention on tail function during locomotion.
Autotomy has evolved in many animal lineages as a means of predator escape, and involves the voluntary shedding of body parts. In vertebrates, caudal autotomy (or tail shedding) is the most common form, and it is particularly widespread in lizards. Here, we develop a framework for thinking about how tail loss can have fitness consequences, particularly through its impacts on locomotion. Caudal ...
متن کاملTail autotomy and subsequent regeneration alter the mechanics of locomotion in lizards.
Animals can undergo significant weight change for a variety of reasons. Autotomy, the voluntary shedding of an appendage in response to a predator stimulus, provides an effective model for measuring the effects of rapid weight change on locomotor behavior and the responses to more gradual weight gain, particularly in lizards capable of both autotomizing and regenerating their tail. Although the...
متن کاملTo cut a long tail short: a review of lizard caudal autotomy studies carried out over the last 20 years
Caudal autotomy, the ability to shed the tail, is common in lizards as a response to attempted predation. Since Arnold’s substantial review of caudal autotomy as a defence in reptiles 20 years ago, our understanding of the costs associated with tail loss has increased dramatically. In this paper, we review the incidence of caudal autotomy among lizards (Reptilia Sauria) with particular referenc...
متن کاملEffect of morphological development on the locomotion function of Nile tilapia, Oreochromis niluticus during early ontogeny
This study was conducted to investigate the hydrodynamic parameters and how morphological changes affect them in Oreochromis niloticus at the National Museum of Natural History-Paris in the winter of 2020. To record fish movement, a high-speed camera (1000 fps) with a macro lens was used. The fish trajectory was taken by calculating coordinates of a center point between the two eyes and kinemat...
متن کاملIntegrative biology of tail autotomy in lizards.
Self-amputation (autotomy) of the tail is essential for the survival of many lizards. Accordingly, it has garnered the attention of scientists for more than 200 years. Several factors can influence the release of the tail, such as the size, sex, and age of the lizard; type of predator; ecology; and evolutionary history of the lineage. Once lost, the tail will writhe for seconds to minutes, and ...
