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.
Sunflower sea star regenerates its arms. 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.

The tail is used in courtship and as a storage organ for proteins and lipids. It also functions as a defense against predation, when it may be lashed at the attacker or autotomised when grabbed. Unlike frogs, an adult salamander is able to regenerate limbs and its tail when these are lost. [14]
Such species generally can regenerate the lost part of a tail, though imperfectly. A lost tail can grow back within around three to four months. [6] Species with stumpy tails have no special regenerative abilities. Some species of skinks are quite small; Scincella lateralis typically ranges from 7.5 to 14.5 cm (3 to 5 + 3 ⁄ 4 in), more than ...
The regeneration of the lens has been studied in several vertebrate species, especially the newt, which is able to repeatedly regenerate a perfect lens. [11] One study found that the lens of a newt that had been extracted and regenerated 18 times was indistinguishable from the lens of a control newt in terms of appearance and gene expression. [12]

Branding expert Doug Eldridge told Fox News Digital, "Given the scope and scale of devastation in California, this is a time to focus on the people and places that truly matter in life."
A dragonfly in its radical final moult, metamorphosing from an aquatic nymph to a winged adult.. In biology, moulting (British English), or molting (American English), also known as sloughing, shedding, or in many invertebrates, ecdysis, is a process by which an animal casts off parts of its body to serve some beneficial purpose, either at specific times of the year, or at specific points in ...
