Brigalow scaly-foot description

GenusParadelma (1)

Although snake-like in appearance, the Brigalow scaly-foot is actually a legless lizard, with no external evidence of any forelimbs and hindlimbs that are so greatly reduced that only small flaps remain (3). The fairly short but heavy-set body of the Brigalow scaly-foot is glossy dark brown to dark grey, with an opaque, milky sheen (2) (4). The scales covering the body often have dark centres, giving a faint impression of a striped pattern running along the body (5) (6). The Brigalow scaly-foot has a rounded snout and visible ear openings (2), and the base of the head is a paler cream colour with a dark band crossing the neck (4). The tail, which can be distinguished from the body only on close inspection, can be up to twice as long as the body (7).

Also known as
Queensland snake-lizard.
Lézard Apode Du Queensland.
Length: up to 16 cm (2)

Brigalow scaly-foot biology

Information on the Brigalow scaly-foot’s ecology and life history is limited. It is certainly a nocturnal, slow-moving creature, probably choosing to hide under stone slabs, logs, loose bark or dense leaf litter during the day (7) (14). It is most active in warm months and inactive when the maximum nightly temperature drops below 19 degrees Celsius. In spite of its small size it has been known to climb trees to heights in excess of two metres (13), and if alarmed, the scaly-foot has been observed to rear its head and flicker its tongue (13).

Sap from the hickory wattle (Acacia fulciformis) forms the main part of its diet, although one study also found spider and insect remains in samples of droppings (13). The same study captured a pregnant female that subsequently laid two eggs. The incubation time was around two months and the hatching process slow (13).


Brigalow scaly-foot range

The Brigalow scaly-foot is found only in Queensland, Australia. Within this state, it is restricted mainly to the ‘Brigalow Belt’, a region of acacia wooded grassland that runs between the tropical rainforest of Queensland’s coast and the semi-desert of the interior (8) (9) (10) (11).


Brigalow scaly-foot habitat

This small legless lizard lives in open forest and woodland, especially on vegetation such as brigalow (Acacia harpophylla) (7), narrow-leaved ironbark (Eucalyptus crebrai) (11), northern silky oak (Cardwellia sublimisi) (7) and numerous other species of Acacia (12) (13). It is also found on sandstone ridges, sheltering below rock slabs and grass tussocks (5) (8).


Brigalow scaly-foot status

Classified as Vulnerable (VU) on the IUCN Red List (1).

IUCN Red List species status – Vulnerable


Brigalow scaly-foot threats

The Brigalow scaly-foot is under threat from a number of different factors. The scaly-foot’s natural habitat (the Brigalow Belt) has been drastically changed by vegetation clearance, much of it for agricultural or urban development (9) (10) (15); as a result, the Brigalow Belt has declined in size by 90 percent from its original area (16).

The removal of rocks, leaf litter and logs, through activities such as burning, slashing and highway widening, destroys vital shelter and protection for the Brigalow scaly-foot (6), and an increasing human population and the introduction of roadside lighting has threatened the population of this nocturnal reptile at an important site known as Boyne Island (13). Additional threats include misidentification as snakes, resulting in persecution, as well as accidental deaths on roads (4), and predation from animals such as foxes (Vulpes vulpes), feral cats (Felis catus) and pigs (Sus scrofa) (6).


Brigalow scaly-foot conservation

Numerous conservation measures for the threatened Brigalow scaly-foot have been recommended, including managing areas of vegetation known to contain populations of this lizard, ensuring highway widening does not impact known populations, and raising awareness of the Brigalow scaly-foot within local communities (17). This species will also benefit from conservation measures outlined in the Threat Abatement Plan for Predation by Feral Cats (18) and the Threat Abatement Plan for Predation by the European Red Fox (19).
