Spotted toad-headed agama (Phrynocephalus guttatus alpherakii)

Keeping and breeding at BION Terrarium Center


Spotted toad-headed agama Phrynocephalus guttatus (Gmelin, 1789) is an agama species native to Kazakhstan (Ili River Hollow) and China. These animals are typical inhabitants of dried ecosystems of deserts and semideserts (Банников et al., 1985; Ananjeva et al., 2006). The genus has been named after the Greek words phrynos = toad and “kephale” = head.

Morphological characteristics of Phrynocephalus guttatus alpherakii Bedriaga 1906 are almost similar to those of Phrynocephalus guttatus. However, some researchers describe the single P. g. alpherakii population in China as separate species Phrynocephalus alpherakii (Sinervo, 2018). But as of now, P. g. alpherakii subspecies status is confirmed by molecular analysis. Therefore the information of Ph. guttatus keeping and breeding given in this article will definitely be useful for people who keep other Ph. guttatus subspecies as well.

Adults’ average SVL is about 6,0 cm (2.4 in), TL – about 8 cm (3.2 in). Average total length is 12-20 cm (4.7 – 7.9 in). Average total length of hatchlings is 6-8 cm (2.4 – 3.2 in) (

Coloration is variable. Dorsal part of the body is sandy gray with numerous fine spots and lines that often form little dark rings (Банников, 1985). Tail coloration is yellowish at the base and black to its end. Heads are round, with sloping edge. Scales are smooth, but often ribbed along the spine. Ventral part of the body is white.

A male can be distinquished from a female thanks to a well-seen thickening at the base of the tail (due to presence of hemipenises), that appears only after sexual maturity at the age of about 8 - 12 months.

They feed mainly on different invertebrates, predominantly ants, bugs, representatives of Orthoptera, Diptera, Lepidoptera and various spiders. Plant debris (leaves and seeds) as well as sand and pebbles are found in their stomachs. These agamas are often killed by various birds of prey and snakes. They are also caught by domestic animals such as dogs and cats. The number of these lizards has been sharply reduced in recent years and due to overgrowing of sand massifs, spread of invasive species, poaching and smuggling. That is why it is important to maintain healthy breeding stock in controlled laboratory conditions in order to meet the needs of the market and save the species if it suddenly disappears in the wild.

An extensive distribution range of Ph. guttatus spreads from western borders of China across the whole northern sub-zone of deserts to the western coast of the Caspian Sea. In Europe the subspecies is distributed in Dagestan, Kalmykia, Stavropol Territory, Astrakhan and Volgograd regions. The main part of the distribution range is situated in Kazakhstan, it occurs also in Uzbekistan (Kara-Kalpakia) and Turkmenistan (Ananjeva et al., 2006). Distribution of Ph. g. alpherakii is limited by Ili River Hollow in Kazakhstan. One isolated population is also found in China (

These lizards can live on different forms of sands. But they prefer to live on fixed sand among rare vegetation, especially between bushes near rivers and they avoid shifting dunes. These agamas are able to bury in sand with the help of fast oscillatory movements of the body. They dig holes up to 10 - 20 cm long, in the form of an inclined course, ending with a small expansion. They usually do it at the base of the bushes. In summer, holes are almost never used. At night Ph. guttatus just cover themselves with sand. They are pretty fast runners and able to jump to a height of 20 cm (7.87 in). Ph. guttatus leads a sedentary lifestyle. Each individual occupies an individual site with an area of ​​several square meters. However it should be mentioned that these toad-headed agamas don’t strictly protect their territories unlike Ph. mystaceus. Females have significantly smaller sites than males.

The most interesting characteristic feature of Ph. guttatus behavior is the frequent twisting of the tail, which plays an important role in their communication with each other. The masking coloration makes them hardly noticeable on the sand, not only for possible enemies, but also for the congeners. Therefore, specific movements of the raised tail with a bright and contrasting white and black color on its underside allow them to detect each other, transmit information and communicate in the distance ( 


Keeping. We keep adults and babies at 50*100*45 cm (19,7*39,4*17,7 in) horizontally oriented terrariums. Adult individuals are kept in groups that consist of one male and several females. Babies (until sexual maturity) can be kept individually or in groups (6-8 unsexed individuals). The decoration of the terrarium includes clear river sand (5-10 cm (2.0-4.0 in) and decorative rocks. Tree branches and logs are used as shelters.

Lighting. Zoo Med 5 UVB lamp is used during breeding season for 12-14 hours per day (9:00-23:00); during winter dormancy – for 4 - 6 hours per day.  Additionally, 40W incandescent lamp is used for heating in the warm end of the terrarium. The opposite end is always cooler in order to make a temperature gradient.

Temperature. Daytime temperature is +28 - +32 °C (+82.4 - +89.6 F), nighttime temperature – +23 – +27 °C (+73.4 - +80.6 F). The highest temperature at the basking point is +45 °C (113 F).  UVB is important for successful breeding.

Humidity. Humidity level is maintained at 30-60% with light double spraying (morning and evening) during the day.

Diet. The main rule: diet should be as variable as possible. We use the same diet for adults and babies. The diet consists of house crickets (Acheta domesticus), Jamaican field crickets (Gryllus assimilis), two-spotted crickets (Gryllus bimaculatus) and Turkestan cockroaches (Blatta lateralis) of appropriate size (5-6 insects per head). We feed adults every other day while babies are fed daily. All insects should be gut loaded and dusted with vitamin-mineral supplementation every other feeding. Sepia or cuttlefish “bone” powder works well as a source of calcium. We gut load the insects with fruit, greens and vegetables and sometimes bee pollen as an additional source of vitamins and bioactive elements.

Animals get water during daily spraying in the morning, so water dish is not necessary inside the terrarium.


When babies reach sexual maturity, they are transferred to adult terrariums and breeding groups (1.2-4) are formed. We provide mild wintering period with slight decrease of temperatures and daytime lighting period. Courtship includes intensive tail waving and head bobbing. Gestation period lasts about 28 days. One female is able to lay 2-3 clutches per season (2-4 eggs in each).

The eggs are transferred to the incubator without changing polarity. A small recess is made in vermiculite and each egg is placed in such a recess individually at no more than 2/3 eggs’ height depth. The eggs are incubated on vermiculite at +28 - +28,5 °C (+82.4 - +83.3 F). Humidity is 75-80%. Incubation period is 26-28 days.

After hatchlings appear, they are transferred to the terrariums. We form groups (6-8 animals) of hatchlings that were born during about three days in order to avoid aggression between juveniles of different age. Babies are kept in terrariums with the same decoration as for adults. Those individuals demonstrating aggression or rapid growth are removed to individual terrariums until maturity and forming of breeding groups.
