The Giant Skink survived on the two tiny islets of Branco and Raso into the early 20th century, on the larger neighbouring islands of Santa Luzia and São Vicente the species is known to have existed, based on subfossil bone findings. The skink was originally an inhabitant of the, in former time existing, dry forests, but was able to adapt to the changing living conditions caused by anthropogenic influence and could also get along in dry habitats.

The animal was about 50 cm long. It was mostly an herbivore, but from time to time also fed on smaller animals.

Someday the inhabitants of the neighbouring islands discovered that the fat of the skinks was very suitable as an ointment. So the animals were cought in masses to be manufactured into ointment.

The last Giant Skink in the wild was seen in the year 1912. The last specimen in captivity died in the year 1940.

In the year 2005 J. A. Mateo, M. G. Márquez and L. F. L. Jurado analyzed excrements of feral cats on the island of Santa Luzia and found at this a maxilla, which they assumed to have originated from an juvenile specimen of the Giant Skink.

Intensive searches on the island one year later however were unsuccessful.
