spontaneous removal or casting off of a body part (as the tail of a lizard or claw of a lobster) especially when the organism is injured or under attack
Heart rate and breathing frequency were lowered, injury of the tail (tail autotomy, a well known phenomenon in dormice), was prevented and staff were not injured during examination and sampling (Long & West 2012).
Caudal autotomy describes the process whereby many reptiles lose or drop a part of their tail due to predator attack or spontaneous contraction of tail muscles (Bateman and Fleming 2009; Wilson 2012; Cogger 2014).
Shifted balance of risk and cost after autotomy affects use of cover, escape, activity, and foraging in the keeled earless lizard (Holbrookia propinqua).
Unlike other holothurians, the stimulation of autotomy with potassium chloride in this species causes a rapid softening and rupture of the body wall over a large area and the organs are expelled through the large opening that is formed [26].
Because of the tendency for autotomy of limbs in southern Tanner and snow crabs, all manipulations were carried out quickly with the greatest possible care.
It has been reported that dietary supplementation with taurine suppresses hyperalgesia in streptozotocin-induced diabetic rats and autotomy behavior in genetically selected Sabra strain rats [38].
Seifert was studying scar-free healing in amphibians when a colleague told him that a small rodent he had observed in Africa seemed capable of autotomy, a defense mechanism whereby the animal self-amputates a body part to escape a predator.
