Rankin's Dragon

Overview

Rankin's dragon, also called Lawson's dragon or the black-soil plains dragon, is the smallest of the eight Pogona bearded dragon species ¹². Adults are about 30 cm (12 inches) long, roughly half the length of a central bearded dragon, and live ten to fifteen years ¹. It is active by day, and it can even be kept in groups ¹.

Natural history

The species lives in central and northwestern Queensland, Australia, on the black-soil plains and the transition into semi-desert ¹²³.

Enclosure

The BGSU Herpetarium keeps Rankin's dragons with ¹:

• Size. At least a 20-gallon aquarium for a single animal. Give more room for a group, and the most you can for any dragon.
• Furnishings. Driftwood, a shelter and a basking spot under a screen cover.
• Water. A shallow water dish; Rankin's dragons like to soak.
• Company. Groups can include more than one male. They will sort out a dominance hierarchy, so watch that everyone is eating and basking.

Temperature & lighting

Use full-spectrum light with an incandescent bulb for heat ¹. Like other bearded dragons, Rankin's dragons are desert-edge, sun-loving lizards. VCA's guidance for bearded dragons calls for a UVB light, a basking light on a day–night cycle and a thermostat ⁴.

Humidity

Rankin's dragons come from dry country ¹². A screen cover and a shallow soaking dish are enough; avoid damp, stuffy setups ¹.

Substrate

Sand over an under-tank heat pad, a sand/soil/sphagnum moss mix, or paper towels ¹. Some breeders prefer a bare-bottom tank, especially for hatchlings ¹.

Diet & supplementation

Rankin's dragons are omnivores ¹.

• Insects. Crickets, dubia roaches, mealworms and superworms, sized no longer than the distance between the eyes ¹.
• Plants. Finely chopped dark leafy greens and mixed vegetables, offered daily to adults ¹.
• Hatchlings and juveniles. Feed what they will eat in 15 minutes and dust daily. Do not leave crickets loose in the cage ¹.
• Adults. Feed every 1–2 days. Dust insects with calcium and vitamins at two feedings a week ¹.

Handling & temperament

Support the whole body and all four feet when you pick one up. Wash your hands after handling: reptiles can carry Salmonella ⁵.

Health

Common issues

• Metabolic bone disease without enough UVB and calcium. Your exotic vet can review your lighting and supplements ⁴⁶.
• Bullying in groups, from the male dominance hierarchy ¹.

When to see a vet

See an exotic-animal vet for appetite loss lasting more than a week, noisy breathing or stuck shed. Open-mouth breathing, limp or oddly angled limbs, large open wounds or an unresponsive animal are emergencies ⁶.

Breeding overview

At the BGSU Herpetarium, Rankin's dragons go through a roughly two-month cool rest (brumation) at room temperature with the lights off before breeding ¹. Females lay clutches of 5 to 18 eggs about two to three weeks after mating, with up to five clutches a season ¹.

Legal & ethics

Buy captive-bred from a breeder who knows the hatch date and parents, and check your state and city rules before you buy or breed.
