This species should never be picked up or restrained by holding the tail as this may result in it breaking off. This defense mechanism sometimes allows them to escape an enemy. The tail breaks at a crack in the vertebra and the surrounding muscles are so arranged that they separate neatly and instantly. A muscle closes around the artery in the tail at the point of the break and prevents undue blood loss. Usually a new tail is regenerated.
