# Central Bearded Dragon (*Pogona vitticeps*)
> **Status**: Checked against 9 sources, listed under Sources below.

> **Vibe Match**: Rapid-fire picado runs over a rolling rumba beat for a lizard that settles a stand-off with its body: the dominant one bobs its head and inflates its beard, the other waves a forearm to submit, and if neither backs down they circle each other.
## Biological Superpowers & Stats
- **Taxonomy**: *Pogona vitticeps*
- **Danger Level**: Low
- **Conservation Status**: Least Concern ([IUCN Red List](https://doi.org/10.2305/iucn.uk.2018-1.rlts.t83494364a83494440.en))
- **Superpower**: Heat can override its genes: high-temperature egg incubation turns genetically male (ZZ) dragons into functional females.
- **Habitat**: Arid to semi-arid woodland, scrubland and desert across inland Queensland, New South Wales, Victoria, South Australia and the Northern Territory; also one of the most popular pet lizards.
- **Diet**: Omnivorous: in the wild, 61% of dry food intake is arthropods, mostly winged termites, and 16% is plants; captive dragons also eat crickets, vegetables and dandelion flowers.
- **Tags**: reptile, desert, woodland, omnivore
## Natural History & Behavior
## When Heat Beats Genetics
A central bearded dragon's sex is normally set by its chromosomes: two Z
chromosomes make a male, and a Z paired with a W makes a female. In 2005,
researchers first identified these tiny W and Z chromosomes in this species,
the first such micro sex chromosomes shown in any agamid, the dragon lizard
family. Heat can overrule that code: high-temperature egg incubation turns
genetically male (ZZ) individuals into functional females. In 2015,
scientists made the first report of a reptile's sex reversing in the wild, in
this species. They then mated sex-reversed females with normal males. The
offspring's sex was set solely by temperature, and the W chromosome was
eliminated from this family line in the first generation.
## Outback Life, By the Numbers
Adults average 288 grams, grow 33 to 61 centimetres from nose to tail, and
may live 10 to 15 years. They are found in arid and semi-arid habitats across
the interior of Queensland, New South Wales, Victoria, South Australia and the
Northern Territory, from eucalypt woodland and acacia scrub to sandridge
desert. They perch on fallen timber, fence posts and large rocks. When
scientists flushed the stomachs of 14 wild dragons, 61 percent of the food by
dry weight was animal matter. Most of it was winged termites: one kind made up
95 percent of the prey items and more than half of the total. Plants made
up 16 percent.
## More Bluff Than Bite
The "beard" sits under the lower jaw. Long scales around the back of the jaw
and along the sides look very spiky, but they are actually quite rubbery. The
Australian Museum says the dragon relies on more bluff than bite, trying to
look larger and spikier than it really is to predators. When alarmed, it faces
the intruder with its mouth wide open and its beard puffed out, and sucks in
air fast to swell its body so it seems bigger. Under direct attack, it shows
the yellow lining of its mouth, darkens its skin, flattens its body, hisses
and makes small jumps at the attacker. Its colour can change fast: one dragon
went from mostly yellow to almost completely black in no more than a few
minutes.
Usually solitary, dragons gather at the best basking spots, where a clear
pecking order shows. A male signals dominance with a fast head bob and an
inflated, blackened beard. Waving a front leg signals submission, which
generally calms the clash. If one won't back down, the two circle each other,
and a stand-off or fight follows.
## Sleep Waves in a Lizard's Brain
Scientists thought the brain-wave patterns of sleep, such as slow-wave and REM
(rapid eye movement) sleep, were restricted to mammals and birds. Recordings
from a dragon's brain found both. That pushes their probable origin back at
least to the first amniotes, the group that includes reptiles, birds and
mammals.
> **A Sleep Rhythm of About 80 Seconds** The dragons' slow-wave and REM
> patterns swung back and forth continuously for 6 to 10 hours, with each full
> swing taking about 80 seconds.
## Frequently Asked Questions
### Why does a bearded dragon puff out and blacken its beard?
The beard sits under the lower jaw, and the long scales around the back of the jaw look very spiky but are actually quite rubbery. When alarmed, a dragon faces the intruder with its mouth wide open and its beard puffed out to make its jaw look larger. Mature males often turn the beard black, and males signal dominance with a fast head bob and an inflated, blackened beard. The colour change can be quick: one dragon went from mostly yellow to almost completely black in no more than a few minutes. *(Source: [Australian Museum]())*
### What is a bearded dragon's third eye for?
It's the parietal eye, and in lizards its light-sensing cells are reported to respond to blue and green light. In an earlier experiment, dragons reacted to an extremely low-frequency electromagnetic field (an invisible electric and magnetic signal made in the lab), but the reaction disappeared when the third eye was covered with a small cap. Those results suggested the eye plays a role in a light-dependent magnetic sense. A 2020 study suggests that sense needs light with a wavelength lower than 580 nanometres. *(Source: [Nishimura 2020]())*
### Why do bearded dragons wave a front leg?
It's called arm waving, and it's a submission signal that generally defuses a confrontation. Both sexes do it: males wave to submit to a dominant male, and females wave, combined with a slow head bob, to show they're responsive to a male. If one dragon won't back down, the two circle each other, and a stand-off or fight follows. *(Source: [Australian Museum]())*
