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.
The tail, which ends in a horny tip, is continuous with the trunk and is often slightly longer. Slow worms exhibit caudal autotomy , the severing of the tail when it is pulled by predators. [ 10 ] When regrown, the tail grows back only to a short stub, probably because loss of the tail does not sufficiently affect the species' locomotion ...
Dwarf yellow-headed gecko with regenerating tail. Regeneration in biology is the process of renewal, restoration, and tissue growth that makes genomes, cells, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage. [1] Every species is capable of regeneration, from bacteria to humans.
Tuatara are greenish brown and grey, and measure up to 80 cm (31 in) from head to tail-tip and weigh up to 1.3 kg (2.9 lb) [10] with a spiny crest along the back, especially pronounced in males. They have two rows of teeth in the upper jaw overlapping one row on the lower jaw, which is unique among living species.
There is a pattern of development and modification through fusion, deletions, and sinking bones. This pattern is determined by the appearance of the ossification centers. Similarities in these centers and their sequences help to show trends in development between species. [ 6 ]
Snake scales also appear to have affected Islamic art in the form of tessellated mosaic patterns which show great similarity to snake-scale patterns. [37] Snakeskin, with its highly periodic cross-hatch or grid patterns, appeals to people's aesthetics and have been used to manufacture many leather articles including fashionable accessories. [37]
The cause was Stage 4 inoperable pancreatic cancer, a representative for The Reptarium, Barczyk's reptile zoo, confirmed to NBC News. Barczyk had initially shared his diagnosis with his following ...
The earliest known eureptile ("true reptile") was Hylonomus, a small and superficially lizard-like animal which lived in Nova Scotia during the Bashkirian age of the Late Carboniferous, around . Genetic and fossil data argues that the two largest lineages of reptiles, Archosauromorpha (crocodilians, birds, and kin) and Lepidosauromorpha ...
