The Solomon Islands skink is one of the few reptiles known to live in a social group.
It also gives birth rather than lays eggs - another unusual trait.
Keeper Dr Katy Upton said it is a "great achievement".
The Solomon Islands skink is also known by a number of other names including:
- The prehensile-tailed skink
- The monkey-tailed skink
- The giant skink
- The zebra skink
The Solomon Islands want to grow their economy, and they see tourism as a key.
