One of the pet lizard owners care and concern is the problem of their lizard tail. For some of the lizard, the tail may easily drop due to some circumstances and it take quite some times to grow back. You may need to read more about lizard tail problems and understand more about it.
Some lizards when confronted with a predator will voluntarily shed their tail. This process is called tail autonomy (self-cut). After the tail is detached from the body it will wiggle around on the ground for a few minutes. This provides a visual distraction and draws attention away from the vulnerable head and abdomen of the lizard. Usually this allows the lizard enough time to make an escape.
Not all lizard species are capable of doing this, the ones that can have fracture points in their vertebrae. The lizard’s blood vessels in the tail area rapidly constrict after autonomy to ensure minimal blood loss. The muscles in this area are also adapted to provide easy shedding of the tail.
The whole process of shedding its tail can be very stressful to the lizard. If this happens while in captivity it is generally a result of stress and careful evaluation of the situation is required to ensure that it does not happen again. A lizard that has recently shed its tail should be kept in its own enclosure while it re-grows the tail. Ensure that this enclosure is kept clean to minimize the chance of infection. Growing a new tail requires the expenditure of a great deal of protein (energy) and fat. This is compounded by the fact that the tail stores a lot fat which is no longer with the lizard. It is widely believed that the energy required to re-grow a tail can negatively effect the reproductive cycle. This happens because the lizard is unable to put enough energy into producing the eggs. In some cases it may take the lizard up to 2 years to completely re-grow the tail.
Hence you may need to take more precautions and careful approach to handle your lizard and try to minimize lizard tail drop possibility as much as possible.
