Gather some knowledge on Lizards Expendable Tail

Some lizards, when confronted with a predator will voluntarily shed their tails. This process is called tail autotomy (self-cut). When the tail is separated from the body, it will wiggle around on the floor for a few minutes. This gives a visual distraction and draws attention away from the vulnerable head and belly of the lizard. Normally, the lizard enough time to escape.

Not all types of lizards are capable of this, those breakpoints do in their vertebrae. The Lizard blood vessels in the tail area rapidly constrict after autotomy to ensure minimal blood loss. Muscles in this area is also easily adapted to offer to pay off the tail.

After a lizard is its tail will begin to grow back a new, but new ones will not look the same as the original. It can have different colors, shapes and sizes. Sometimes more tails grow instead of one that was dropped. The new tail is able to perform all functions of the original, except for autotomy to perform. This is because the new tail has no breakpoints in the vertebrae. For some legless lizards their tails to make nearly 2 / 3 of their height, it loses a stressful ordeal are.

The whole process of shedding its tail can be highly stressful for the lizard. If this happens while in captivity, it is usually caused by stress and a thorough evaluation is needed to ensure that it does not happen again. A lizard, which has recently thrown his tail should be stored in its own cabinet, while the tail grows back. Make sure this box is kept clean to reduce the risk of contamination to a minimum. Growing a new tail, the expenditure of much of the protein (energy) and fat. This is exacerbated by the fact that a lot of fat tail, which is no longer to save lizards. It is generally assumed that the energy required to re-grow a tail may negatively affect the reproductive cycle. This happens because the lizards are not able to get enough energy to produce eggs stabbing. In some cases it may take up to two years to complete lizards re-grow its tail.
