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 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.
A robust, medium-sized gecko, [6] with a large, triangular head. [5] It has a short, flattened, carrot shaped like tail, that ends in a knob. [6] [7] This tail can be autotomised to distract predators, however unlike other lizards they have only one cleavage point at the base, meaning it must sacrifice its whole tail in the event.
The lesser thorn-tailed gecko from Western Australia can shoot goo out of its tail. ... And scientists found unusual creatures such as a rare type of silent frog and a gecko that shoots goo out of ...
Anguinae is a subfamily of legless lizards in the family Anguidae, commonly called glass lizards, glass snakes or slow worms.The first two names come from the fact their tails easily break or snap off.
Anole tails often have the ability to break off at special segments, which is known as autotomy. The tail continues to wriggle for a period after detaching, attracting the attention of the predator and commonly allowing the anole to escape. [62] The tail is regenerated, but it takes more than two months to complete this process.
The researchers compared the genomes of six species of apes, including humans, and 15 species of monkeys with tails to pinpoint key differences between the groups. Our ancient animal ancestors had ...
As a defence against predators, they can autotomize (break off) their tails, and later grow a new replacement tail which gets longer each time they shed their skin. These new tails do not have the bony vertebrae of the original, and instead only have a rod of cartilage. This growth of cartilage does not have the ability to autotomise, so in ...
