Despite there are believes about poisonous or venomous lizards in Africa – there are none.
East Africa is rich of many species, some only in small areas (endemic), some widespread.

55 species of GECKOES (Family Gekkonidae) are recorded in East Africa. You recognize them by their slightly triangular head, the soft mat skin and the enlarged pad at the end of toes and fingers. Tiny hair-like structures in these pads enable them to go up walls, even to our eyes smooth surfaces and ceilings. Most of the geckoes are nocturnal, some diurnal.

Tropical house geckos (Hemidactylus mabouia) are wide spread and the most often seen geckos. They hunt insects
attracted by artificial lights. Like many geckos they are capable of producing clicking or chirping sounds for communication.

 

 

 

 

Dunkelgruener_Taggecko

Dull-green Day Gecko (Phelsuma dubia). Local along coast in Kenya and Tanzania. It is arboreal and diurnal. Day Geckos are very popular among reptile keepers and because of concern of the possible effect of this international trade, are placed on Appendix II of CITES.

 

 

 

 

 

 

 

 

 

 

 

 

SKINKS (Family Scincidae) are shiny-bodied with no obvious neck. Males and females often have different colours.

and 50 cm long. You see a dark coloured ear opening and
rough scales. The head is in a line with the body.

OLD WORLD LIZARDS (Family Lacertidae)

Alpine-Meadow lizard (Adolfus alleni) occurs on Mt. Elgon and
the Aberdares between 2700 and 4500 m. We found this individual
in the Aberdares at an altitude of about 2.900 m.

Jackson’s forest lizard (Adolfus jacksoni) is a up to 25 cm long lizard.
It is diurnal and arboreal. 2 eggs are layed under bark or leave litter.

Southern Long-tailed Lizard (Latastia longicaudata) is the largest East African lacertid, reaching from head to tail tip up to 40 cm. It can be found in many
parts of Kenya and Northern Tanzania. Its prefered habitats are commiphora-acacia bushland and Somali-Maasai semi-desert. The diet consist of insects.

 

 

 

 

AGAMAS (Family Agamidae) are small to medium sized diurnal lizards. The head is visibly triangular. Males have colorful heads which serves marking the territory by moving it up and down. Females are quite well camouflaged. The females are very similar in the different species and best to identify is having a good look at the males.

The classification of the agamas in East Africa is undergoing new researches.

Are mostly to be found on trees, but also as this one here on a termite mound where it finds good shelter. When displaying colours males are blue.

CHAMELEONS (Family Chamaeleonidae) are peculiar reptiles. They can move their eyes independently and only focus with both in the same direction when the are in the process of catching an insect with their long, fast moving tongue. They are changing colour according to temperature and their mood.

 

 

 

 

Lappenchamaeleon
Chamaeleo gracilis

 

 

Slender Chameleon (Chamaeleo gracilis) are hard to differentiate from the Flap-necked chameleon. In parts of their distribution area especially South-Eastern Kenya both coexist. These were found in Amboseli NP. When chameleons are stressed the full bounty of their colours show.

 

 

 

 

 

 

Lappenchamaeleon_drohend

 

Flap-necked chameleon (Chamaeleo dilepis) reach 15-25 cm in lenght. The female digs a long tunnel and lays 20 - 40 small eggs, which may take 9 months to hatch. They can be found in various areas in Kenya and Tanzania.

Von Hoehnel Chameleon (Trioceros (Chameleo) hoehnelii) are restricted to Narobi region, Aberdares - Mt. Elgon highlands, 1.500 - 4.000 m. Gives live birth to 7 to 18 young. A study in the Aberdares has shown that they can survive at a temperature of minus 2 degrees C.

 

Jackson’s Chameleon (Trioceros (Chameleo) jacksoni) is often seen in Nairobi areas, and up to the Nyambeni hills which is its main distribution area. The female only has tiny horn and is darker. Males reach up to 38 cm, females around 20 cm. They give life birth between 7 and 28 young, which means the female carries the eggs in her body until the young hedge.

Side-striped chameleon (Chamaeleo bitaeniatus) can be met from Central- to Westkenya. It only reaches about 16 cm in lenght. 6 – 15 young are born.

 

 

 

 

 

 

MONITOR LIZARDS (Family Varanidae) are quite large reptiles feeding on other animals or their eggs. 2 species occur in Kenya/Tanzania.

We were driving along an idyllic side river of the Galana River in Tsavo East. Suddenly I saw something falling down the embankment on the other side of the river. Than the head of a rock monitor was seen in the middle of the small river. It took us some time to realise that the White-throated rock monitor (Varanus albigularis) was in the firm grip of a slightly larger crocodile. The scratches of the crocodile's claws were clearly visible on the vertical 1.2 m tall wall from were it pulled the rock monitor into the water. The rock monitor was probably foraging and not aware of the danger coming from its relative in the river. Through struggling it managed to free itself, climbed a rock on our side of the river. Swiftly the crocodile followed grabbed its tail and hind leg. Again the rock monitor pulled and run for 2 m, just to be taken by the croc again. This time the croc pulled it back into the water were it just managed to keep its head on the surface. They remained almost at the same spot and after 45 minutes when we left, it was only to be assumed that the crocodile won.

Nile monitors (Varanus niloticus) reach about 2.5 m. The long tail can be used as a pain inflicting weapon. Their habitat is through out Africa near water. They are excellent swimmers. Equipped with conical teeth they crush anything edible like crustacean, mussels, insects, eggs (of birds and crocodiles), amphibians and reptiles. They lay their eggs in still active termite mounds where they are incubated in an ideal climate. They have a purple forked purple tongue.

Feared, killed for their skins but still fascinating are the Nile crocodiles (Crocodylus niloticus, Ordnung crocodiles/Crocodylia, Familie true crocodiles/Crocodylidae) ). In East Africa these archetypical lizard can get up to 5 m and 1 t. They are the carnivore with the highest mortality of their offspring. Out of 20 – 95 lied eggs only 1 % reaches adulthood. Even the mother guards the nest and the hatchlings, the enemies are too many. Nile monitor, birds of prey, big fishes, large snakes, adult crocodiles and mungoose are among them.
