Autocannibalism, also known as self-cannibalism and autosarcophagy, is the practice of eating parts of one's own body. [1] [2] Generally, only the consumption of flesh (including organ meat such as heart or liver) by an individual of the same species is considered cannibalism. [3]
After testing this mixture on 24 rats with spinal cord injuries, only one rat had chewed its toes after a two- to three-week period. [7] Once rats engage in autoaphagia, they continue with self-injurious behavior until the body deteriorates. [3] Contrary to rats, in humans, there need not be a sensation of physical pain which leads to autophagia.
Autophagy was first observed by Keith R. Porter and his student Thomas Ashford at the Rockefeller Institute.In January 1962 they reported an increased number of lysosomes in rat liver cells after the addition of glucagon, and that some displaced lysosomes towards the centre of the cell contained other cell organelles such as mitochondria.

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.
Atg1 is a kinase upregulated upon induction of autophagy. Atg13 regulates Atg1 and together they form a complex called Atg13:Atg1, which receives signals from the master of nutrient sensing – Tor. Atg1 is also important in late stages of autophagosome formation. [8]
