A white-headed dwarf gecko with tail lost due to autotomy. Autotomy (from the Greek auto-, "self-" and tome, "severing", αὐτοτομία) or 'self-amputation', is the behaviour whereby an animal sheds or discards an appendage, [1] usually as a self-defense mechanism to elude a predator's grasp or to distract the predator and thereby allow escape.
Hox genes play a massive role in some amphibians and reptiles in their ability to regenerate lost limbs, especially HoxA and HoxD genes. [1]If the processes involved in forming new tissue can be reverse-engineered into humans, it may be possible to heal injuries of the spinal cord or brain, repair damaged organs and reduce scarring and fibrosis after surgery.
The ability and degree of regeneration in reptiles differs among the various species (see [111]), but the most notable and well-studied occurrence is tail-regeneration in lizards. [112] [113] [114] In addition to lizards, regeneration has been observed in the tails and maxillary bone of crocodiles and adult neurogenesis has also been noted.
In spring where there is no breeding, ctenophorus caudicinctus has more sodium and potassium in their plasma and lower water influx and efflux. However, in autumn there is an increase in water metabolism. There are higher water influx and efflux but less sodium and potassium in their body. Their total body water is higher in autumn than in spring.
A serpentine reptile with vestigial limbs. It shows evidence of different osteoderm morphology after tail regeneration. Placosauriops "Placosauriops abderhaldeni" [55] Kuhn, 1940 A type of melanosaurinin Glyptosaurine of dubious assignment, as the type material has not been adequately diagnosed. Boidae: Eoconstrictor: Eoconstrictor fischeri [56]
Tropidophorus grayi, commonly called the spiny waterside skink, [1] Gray's keeled skink, Gray's water skink, and the Philippine spiny stream skink is a relatively abundant but secretive skink species, a lizard in the family Scincidae.
The study of the traditional reptile orders, customarily in combination with the study of modern amphibians, is called herpetology. Reptiles have been subject to several conflicting taxonomic definitions. In Linnaean taxonomy, reptiles are gathered together under the class Reptilia (/ r ɛ p ˈ t ɪ l i ə / rep-TIL-ee-ə), which
Nevertheless, lateral undulation cannot be disregarded as a potential swimming style; vertebrae near the hips have extended transverse processes, which are associated with powerful undulating tail muscles in reptiles such as crocodilians. Tail movements may be more effective for swimming than paddling or thrusting with the hindlimbs, since the ...
