Gray examined another preserved specimen of D. marmoratus (from a different donor) which was discoloured, leading him to mistakenly describe it as a separate species (Goniodactylus australis) in the same publication.

[5] A study conducted by King in 1977 showed that C. marmoratus exhibits considerable geographic variation in karyotype across its range.

Fully regenerated tails are characterized by an abrupt change in dorsal skin colouring and pattern at the level of the original fracture plane.

[12] During the hot summer months they generally use deep crevices and burrows as their daytime retreat sites, and in cooler weather they aggregate under rocks.

[8] It has been suggested that this activity may be related to mating success, increased vigilance[16] or simply attraction to high-quality habitat.

Subsequent investigation by Kearney and Predavec (2000) revealed that C. marmoratus may thermoregulate by adjusting its posture, for instance, by raising or flattening the body to contact the rock substrate.
