The Scincidae


The genus Hemisphaeridon is a monotypic genus from Australia whose species was formerly considered a member of the Tiliqua. This lizard is much better known by its common name, the Pink-Tongue Skink. Although similar in appearance to the Blue-Tongues, its behaviour and habitat are somewhat different. It is more arboreal, and the long tail (up to 1½ times the snout-vent length) is prehensile. Unlike the Blue-Tongues, Pink-Tongues dart their tongues frequently in and out.

Behaviourally this is a nocturnal or crepuscular species.

The animal below was photographed in the spring. It was living in the woodpile of Maleny Lodge in Maleny, Queensland, whose owners sent me the following note:

"He has a lot of attitude! is very aggressive - will not back off or run away and strikes; he has a pink forked ..... He/She is about a foot long and when you just see the head it looks like a snake. He has very short legs and sometimes just rests on his abdomen looking like a short, chubby snake."

Pink-Tongues have been kept successfully in captivity, but the most important thing to remember is that most seem to prefer snails and slugs as their diet. While this might seem easy to provide for those people whose gardens are overrun with these gastropods (especially in Britain), it should be stressed that any pesticide lingering within a wild-caught snail could be highly detrimental to any animal, not least a lizard, eating it, so it is important to make sure as much as one can that pesticides have not been used in the area where the snails or slugs have been collected. Other alternatives to collecting gastropods from the garden include the purchase of aquatic snails from aquarium shops or the setting up of a few African land snails or similar to breed a supply. Rogner recommends the snail species Cepaea nemoralis and Cepaea hortensis, which can be frozen and kept in a fridge.

Apart from gastropods, Pink-Tongues will eat insects such as crickets, sweet fruits and occasionally vegetable matter. Dog food will not be refused, although this should probably be offered only very sparingly. For other details on captive husbandry and breeding, see Rogner or Walls.

Scientific Name Common Name Distribution Size Notes
H. gerrardi Pink-Tongue Skink [D: Schneckenskink, Rosazungenskink, Schnecken- Blauzungenskink, NL: slakkenskink] Australia (eastern coast and ranges of Queensland as far north as Cape York Peninsula and as far south as Blue Mountains, New South Wales) 16-20" Found mainly in wet sclerophyll or rainforest, but also in the north in monsoon and dry sclerophyll forest. Scalation details: nasals separated; prefrontals in contact; 3 supraoculars; anterior temporals not elongated; no enlarged hexagonal scales between parietal and normal nuchal scales; post-narial groove absent. Ear opening has 1-2 small anterior lobules. Dorsal scales smooth in 30-34 rows at midbody. Coloration: overall silver-grey to fawn- or rich brown, sometimes unmarked but usually with a pattern of 6-8 transverse dorsal bands that point backwards on the sides: these vary in width from animal to animal but if wide enough may show traces of a pale stripe within the darker area. There are a further 8-12 bands on the tail. Ventrally pale purplish-brown, and there may be 2-3 broad transverse bands on the throat. On the head there are a few labial scales with dark margins and may be 1-2 conspicuous dark bars below the eyes and extending to the throat. See Cogger for further details. Reproduction: a male may follow a female for some time (up to a few days) before she is ready to mate. Gestation takes about 5 months: females give birth to up to 25 live young. Rogner notes that in captivity the Pink-Tongues are more likely to breed if they have had a winter rest period, and both he and Rogner recommend that the newborns be separated from the adults.

Blue-Tongued Skinks: Keeping and Breeding Them in Captivity, Jerry G Walls, TFH 1996. Walls writes well on most herpetological and invertebrate subjects, and this brief book is no exception, covering the taxonomy and requirements not only of the Tiliqua species but also of Cyclodomorphus (Oak Skinks), Hemisphaeriodon (Pink-Tongued Skink) and Trachydosaurus (Pine Cone Skink).

Echsen [Lizards] Vol 2, Rogner, Ullmer Verlag, 1992. Usually a very good source of information. The section on the Pink-Tongue Skink is listed as Tiliqua gerrardi.


Mark Bond's Pink-Tongue Skink Information Centre is based largely on Mark's own experiences and also has other interesting animals featured, such as Fire Skinks and Sugar Gliders.

The Forked Tongue, the Monthly Newsletter of the Greater Cincinnati Herpetological Society, has an article by Mark Bond on page 2 of their October 2002 edition (Acrobat PDF format).
