Warty Chameleon (Furcifer verrucosus) Care Sheet
The Warty Chameleon (Furcifer verrucosus), also known as the Blue-Legged Chameleon, is a large Madagascan chameleon adapted to relatively dry, open and seasonally harsh environments.
It is very different in husbandry from cool, humid forest species such as Parson’s Chameleon. Furcifer verrucosus is naturally associated with:
- Dry forest
- Thorn scrub
- Open woodland
- Semi-arid scrubland
- Bushy vegetation
It tolerates higher daytime temperatures and lower daytime humidity than many rainforest chameleons, but still requires:
- Strong hydration
- Good nighttime humidity
- Excellent ventilation
- Appropriate nighttime cooling
- Powerful visible lighting
- Suitable UVB
- Substantial climbing space
- Dense shaded retreats
Large males are impressive, strongly built chameleons and may exceed approximately 45–50 cm (18–20 in) total length.

Enclosure philosophy
The enclosure should reproduce:
a bright, warm, dry-forest shrub canopy with abundant shade.
Adult male enclosure
For one adult male, provide at least approximately:
120 × 90 × 180 cm (4 × 3 × 6 ft).
Preferred enclosure
Approximately:
180 × 90 × 180 cm (6 × 3 × 6 ft)
or larger is strongly preferred.

Temperature
Warty Chameleons tolerate substantial daytime warmth.
Day ambient temperature
Maintain most of the enclosure around:
24–29°C (75–84°F).
Warm upper zone
The upper warm section may reach:
28–31°C (82–88°F).

32–35°C (90–95°F).
Female basking
Females generally do well around:
29–32°C (84–90°F).
Avoid extreme basking heat
There is no need to provide temperatures approaching:
40°C+ (104°F+).
Cool area
Maintain cooler shaded regions around:
21–24°C (70–75°F).
Thermal choice
The animal should always be able to move among:
- Hot exposed basking
- Warm branches
- Moderate shaded areas
- Cool foliage
Night temperature
Allow nighttime temperatures to fall toward:
16–21°C (61–70°F).
Night cooling
