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.
An Ohio-based pet gecko breeder recently shared some footage that isn’t for the fainthearted, featuring a “dropped” gecko tail rolling around independently of the reptile’s body.Dennis ...
Adults of most anoles are between 4 and 8 cm (1.5–3 in) in snout-to-vent length, [46] and between 10 and 20 cm (4–8 in) in total length, including the tail. [ 1 ] [ 8 ] In the smallest, the five-striped grass anole , the snout-to-vent length is about 3 and 3.5 cm (1.2 and 1.4 in) in females and males respectively, [ 2 ] [ 46 ] but it is a ...
Like other species of gecko, individuals of G. japonicus primarily eat insects. The species is capable of autotomy, and will separate its tail from its body to escape predators. While this process avoids bleeding, as blood vessels at the base of the tail close to prevent blood loss, the gecko does lose a supply of fat tissue, which it can use ...
To fully explain why beavers slap their tails we need to look at their social structures. They live in colonies of around 8 to 12 individuals and form strong family bonds.
The African fat-tailed gecko is equipped with the ability to lose its tail when threatened or attacked. If the tail is lost, the new tail will have a more rounded shape, similar to the head. It may not match the body coloration and pattern of the gecko. The tail is also where they store their fat, an important energy reserve.

The tail can be dropped (via caudal autotomy) to distract predators. The crested gecko does not regenerate its tail once lost. Most adults in the wild lack tails. [4] The toes and the tip of the semi-prehensile tail are covered in small hairs called setae. Each seta is divided into hundreds of smaller (approximately 200 nanometres in diameter ...
