Veiled chameleon

Chamaeleo calyptratus

Also known as Cone-head Chameleon, Yemen Chameleon

Reptiles › Lizards (Lacertilia) › Chamaeleonidae (Chameleons)

Veiled chameleons are hardy for chameleons but need tall, ventilated enclosures, high humidity and strong UVB. They live about 4–7 years.

Care guide

Enclosure

  • Minimum 24×24×48 in, tall and well ventilated, with strong UVB (10–12%) about 12 hours a day.

Sources 58

Feeding

  • Dust live insects and remove any not eaten within 30 minutes.

Chameleons

Applies to most species in this group. Habitat: Tropical and montane forests. Individual species can differ, so compare with the species numbers above and the linked sources.

Housing & setup

  • Screen or hybrid enclosures with lots of live plants and branches; good airflow.
  • Daily misting or a dripper; chameleons rarely drink from bowls.
  • Montane species (Jackson's, Meller's) need cooler temperatures than veiled or panther chameleons.

Climate & lighting

Starting point only: Jackson and panther day/night regimes differ; VCA and RF also disagree and must remain separate. Check the species-specific values for this animal where shown.

Diet

  • Gut-loaded insects dusted with calcium and multivitamins on a schedule.

Sources 1131145850219220221222

Social life

  • Solitary; even seeing another chameleon can stress them.

Sources 1131145850219220221222

Handling

  • Minimal handling; they're display animals.

Sources 1131145850219220221222

Health watch

  • Dehydration, MBD, eye problems and stress from handling or seeing other chameleons.
  • House singly.

Understanding the animal

In the wild

In the wild

Researched for this exact species, not its family. Good care copies these conditions.123456

Where it livesSouthwestern Arabia, particularly Yemen and southwestern Saudi Arabia; uses shrubs and trees in vegetated wadis, foothills and cultivated landscapes. Often occupies low vegetation by day and higher branches at night.
Ground it lives onarboreal; shrubs and branches; females descend to dig egg nests
ClimateNative habitats range from semi-arid to tropical, with monsoon rainfall approximately May–September and cooler highland conditions. Reliable species-wide wild temperature and relative-humidity ranges were not established.
ActiveDiurnal.
Social lifeSolitary and territorial; males display and fight over access to females.
Wild dietPrimarily insects; also consumes plant leaves.
Behavior to plan forUses gripping feet and a prehensile tail to climb, and captures insects with a projectile tongue. Females dig underground egg nests.

What this means for care

  • Provide densely planted climbing routes and elevated sleeping branches.
  • House separately with visual barriers between individuals.
  • Provide females with a substantial diggable laying area.
  • Include hydration and drying cycles; vegetated wadi habitats do not support constant desert dryness.

Measured at 67 wild occurrence records sampled against WorldClim 2.1 climate data (1970–2000 averages). Air conditions in the range are ecological context, not enclosure settings: microhabitats such as burrows, leaf litter or basking rocks can be cooler, warmer or more humid.

Profile

Profile

Researched for this exact species. Sources are listed under In the wild above.

History

The species was described as Chamaeleo calyptratus by Duméril and Bibron in 1851 and has accumulated several later synonym names. Reptiles Magazine states that captive specimens were once difficult to obtain without relying on wild-caught animals, but the large majority sold today are captive bred.

Keeper tips

  • Use a tall, well-ventilated enclosure; ReptiFiles recommends at least 24 x 24 x 48 inches and preferably larger.
  • Provide branches and vines for climbing.
  • Provide abundant live or artificial foliage, with live foliage preferred by ReptiFiles.
  • ReptiFiles recommends UVB lighting and an additional LED plant/light bar.
  • Use temperature and humidity gauges to monitor enclosure conditions.
  • Provide a misting and dripping water system as recommended by ReptiFiles.

Behaviors reported

  • Lives primarily above the ground in trees and other vegetation.
  • Can occupy both dry areas and wetter mountain-associated habitats.
  • Is described by Animal Diversity Web as aggressive.

Unique adaptations

  • Wide, splayed zygodactyl feet.
  • Bulging eyes that can move independently.
  • A curled tail.
  • A prominent casque on the head, especially large in mature males.

Remarkable facts

  • Males can reach roughly 17-24 inches in total length, while females are smaller.
  • Males have larger casques than females and are born with tarsal spurs that allow easy sex determination.
  • Animal Diversity Web reports sexual maturity at about 4-5 months.
  • The Reptile Database identifies the species as oviparous.
  • Reported lifespan is generally shorter in females than males; sources give males about 6-8 years or up to 8 years and females roughly 4-6 years or about 5 years.
  • Introduced populations are reported in Florida, and Reptiles Magazine also reports established populations on Maui, Hawaii.

OverviewThe veiled chameleon (Chamaeleo calyptratus) is a species of chameleon (family Chamaeleonidae) native to the Arabian Peninsula in Yemen and Saudi Arabia. Other common names include cone-head chameleon, Yemen chameleon, and Yemeni chameleon. They are born pastel green and without their distinctive casques on their head. When newly hatched veiled chameleons are surprised, they may drop to the ground and turn a bright red color due to stress. — Wikipedia (community-edited)
Where it livesRange: Yemen, SW Saudi Arabia (up to 2500 m). — The Reptile Database
Wild dietThe veiled chameleon is an insectivore. — Animal Diversity Web
BehaviorVeiled chameleons are shy in nature. — Animal Diversity Web
ReproductionThe lifespan of a veiled chameleon is usually five years for females and up to eight years for males (Crabtree, 1999). — Animal Diversity Web
Appearance and sizeThe veiled chameleon is characterized as an aggressive, brightly colored chameleon. — Animal Diversity Web
History and namingNamed after Greek kalyptra > L. calyptra, veil or cover; Latin -atus/a/um, adjectival suffix: veiled or covered, denoting the presence of an extremely elevated casque (Charles Klaver, pers. comm., 11 Jan 2023). — The Reptile Database
ConservationWild chameleon populations are experiencing growing pressures on a variety of fronts, causing some environmentalists to sound alarms concerning the long-term survival of these animals. — Animal Diversity Web
