Prehensility in the tails of Varanids (Monitor Lizards)

[infernalis]

As noted and photographed in the behaviors of Littlefoot & Cera, They have both displayed use of their tails in both balance and grasping to assist in climbing.

The use of the tail for grasping and balance is nothing new, and quite common in all arboreal species, and some terrestrial species, But I have not found anything implicating that this is a common practice in the stoutly built African species such as V. exanthematicus.

In layman's terms, has anyone else who keeps captive Savannah monitors witnessed the use of their tails for climbing down from elevated locations?

As we all know, these lizards posses very strong tails, yet very little is mentioned of the use of this tail in daily activity aside from a good slap when angered.

Evidence is building that Savannah Monitors are actually quite good at climbing, witnessed both in captivity and in the wild, the use of the tail to assist in this activity is of great interest to me.

So, share your observations, have you seen your lizards use their tails as a means of grasping or balancing while moving about?
