Missing legs sometimes happen. It could be for a number of reasons such as it got stuck during the molting process, got damaged after it molted, got damaged just before it molted. If the leg was damaged just before the molting took place the T wouldn't have had enough time to regenerate a new one. Sometimes a T will remove a leg on its own if the damaged limb impedes its ability to function properly.My B. emilia molted recently and I noticed today that it is missing a leg. What causes this and will it grow back?
