Study of Reptiles


The Department of Lower Vertebrates was created in April 1971 when Dr S.W.P. de Waal (1971-1980) was appointed Head of Department. During this period the Department of Lower Vertebrates conducted research exclusively on amphibians and reptiles. Prior to this, Dr A.C. Hoffman (1930-1944) had been involved with a variety of herpetological research.

In 1982, shortly after Mr J.H. van Wyk (1982-1988) was appointed Head of the Lower Vertebrate Department, the Department was re-named Department of Herpetology. Subsequent Heads of Department were Dr L.H. du Preez, Dr A.F. Flemming, Dr N.J.L. Heideman and Dr R.M. Douglas (see Research and Publications for further detail).

The Department has the following aims:

  • To conduct research on reptile and amphibian taxonomy.
  • To conduct research on the ecological and environmental aspects of the biology of southern African amphibians and reptiles.
  • To collect, maintain (curate), and research the amphibian and reptile collections.
  • To make the collections available to other researchers.
  • To disseminate research results and other information through the scientific and popular media.
  • To provide educational services and assistance to other institutions and members of the public.
  • To conserve all southern African amphibians and reptiles.

While at the Museum he obtained the following qualifications: Southern African Museums Technical Certificate in Biology (1988, with distinction); MSc in Environmental Biology with a thesis titled "Investigations into the ecology of the herpetofauna of Florisbad Research Station, Orange Free State, South Africa" (1993, University of Natal, Durban); Interdisciplinary PhD in Geology and Geography with a thesis titled “A new perspective on the geohydrological and surface processes controlling the depositional environment at the Florisbad archaeozoological site” (2009, University of the Free State, Bloemfontein).

Apart from his research Rod was also responsible for the maintenance of the live displays in the Museum, which are a great attraction.

Rod retired at the end of May 2012.


Visit to european Museums

Visit to European museums

8 December 2011
Dr Michael Bates of the Herpetology Department visited the natural history museums in London, Paris and Berlin during September and October 2011 as part of an ongoing research project on the taxonomy of egg-eating snakes of the genus Dasypeltis.  He examined hundreds of preserved snakes, including type specimens (specimens used for original descriptions) of various species.  More than 20 external features were examined on most specimens, and selected specimens were also photographed.  The results of this study will be published in several parts.

Live Displays

Live-Displays-banner

The live displays were established to showcase unusual animals, known only by name to many people, and rarely seen.  These animals also serve as living examples for lessons provided by the Education Department for school groups, helping to stimulate a keener interest.

Vertebrate live displays

Herpetology Hall

The National Museum vertebrate live displays, which are some of the most popular exhibits in the Museum, include the following:

Snakes

Red-tailed Boa (Boa constrictor)
Red-tailed Boa (Boa constrictor)

Some of the most popular displays in the Museum are the live displays, and in particular the snake display. The nearly 4-m-long female African Rock Python (Python natalensis) that was on display for many years was a great attraction, particularly among visiting school groups. Unfortunately she died in July 2010 after refusing to eat for some time. Owing to her popularity with the public it was decided to replace her with some other large constrictor. Other constrictors, such as the African Rock Python (P. natalensis), Burmese Python (Python molurus bivittatus), Reticulated Python (Python reticulatus) and Anaconda (Eunectes murinus), were considered unsuitable as they would eventually become too large for the existing cage and would also be a problem to feed later on.

It was therefore decided that Boa Constrictors would be ideal for the display as neither their size nor feeding would be a problem. A male and a female Red-tailed Boa were duly purchased. The Boa Constrictor (Boa constrictor) is one of the few animals whose common name is the same as its scientific name. Boa Constrictors usually grow to about 2,5 m in length, although females may grow to 4 m, and weigh up to 27 kg.

All boas and anacondas belong to the Family Boidae, as opposed to pythons who belong to the Family Pythonidae. Until more recently pythons were considered a subfamily (Pythoninae) of the Boidae and hence boas and pythons were referred to as boids. Generally pythons are found in the Old World (Africa, Asia, Australia) while boas live in both the Old World and the New World (North, Central and South America). There are 10 subspecies of Boa constrictor which live in a variety of habitats from tropical rain forest, to savanna, to desert. However, most occur in tropical rain forests due to their preference for high humidity and temperatures. They are semi-arboreal and nocturnal, preying largely on smaller mammals and birds, with the bulk of their prey comprising rodents. Lizards may also be taken.

Characteristically, the females of both Families attain greater lengths than males, with the males and females of both Families exhibiting the primitive characteristic of a vestigal pelvic girdle. The hind-limbs of the pelvic girdle are visible externally as pelvic spurs, located on either side of the vent, with male spurs being much larger than female spurs. A clear distinction between boas and pythons is that boas give live birth (viviparous), while pythons lay eggs (oviparous).

The distribution of the species Boa constrictor extends from northern Mexico, southwards to Argentina north of 35° S. They also occur on many islands along the coast of Mexico and South America. Some subspecies have only very subtle differences in markings and colouration, and their status as separate sub-species is controversial. On the other hand, colour and pattern variations within a particular subspecies may be sufficient to lead to the assumption that a specimen may well be a different species or subspecies. Captive cross-breeding has made matters even more complicated and it is often very difficult to determine which subspecies a specimen may be, particularly in the Red-tailed Boa group. This is the most commonly kept captive species.

It is sincerely hoped that the public will get many years of pleasure from viewing our two new acquisitions.

The other occupant of this display is a large American Yellow Rat Snake (Elaphe obsoleta).

Common Platannas

(Clawed Frog) (Xenopus laevis)

These unusual amphibians spend their entire lives in water, although they may move overland for brief periods in search of an alternative habitat. The way in which Platannas stuff food into their mouths with their front limbs is fascinating for visitors. Common Platannas, originally from Africa, have now established themselves in many parts of the world.

Yellow-bellied Terrapin

(Pelusios c. castenoides) (freshwater)

There is presently one Yellow-bellied Terrapin on display and it has been a popular exhibit for many, many years. The extended periods of time this Terrapin spends resting on the bottom of its tank often has visitors worried.

Cichlid fish

A large tank contains various cichlid fish, mainly colourful Malawian species, which brighten up this corner of the Herpetology Hall. Fish may appear out of place in this Hall, but were included here to provide a valuable resource for the Education Department to illustrate their lessons to school groups.


Invertebrate live displays

Invertebrate Hall

Australian Redclaw Crayfish

(Cherax quadricarinatus)

African Freshwater Crabs Potamonautes warreni
The freshwater Australian Redclaw Crayfish tank is a very popular exhibit containing a number of crayfish in a rocky habitat. Their bright blue bodies and red claws make them ideal for live exhibition purposes.

African Freshwater Crabs

(Potamonautes warreni)

The African Freshwater Crab display is relatively new. Although referred to as an aquatic species, the African Freshwater Crab is amphibious and can spend considerable time on land, breathing air. These crabs have well developed lungs but retain gills. Freshwater crabs are seen as environmental indicators, reflecting the quality of their habitat, and are useful in biomonitoring.

Cockroaches

Madagascar Hissing Cockroach Gromphadorhina portentosa
There are two live cockroach displays, one containing Madagascar Hissing Cockroach (Gromphadorhina portentosa), the other Common House Cockroach (Blattella germanica). Unlike other insects, the Hissing Cockroach female (up to 7 cm long) does not lay eggs but retains the developing embryos inside her body, giving birth to live young. Despite the human loathing of cockroaches, the public are fascinated by these displays.

Bee Hive

A functional African Bee (Apis mellifera) hive has been established in the Museum behind glass, where the daily activities of bees can be observed at close range. This display holds visitors spellbound for ages while they try to locate the Queen bee.

Dr Michael Bates of the Herpetology Department at the National Museum and his co-author Dr Donald Broadley (Natural History Museum, Bulawayo) recently published an extensive review of the egg-eating snakes of north-eastern Africa and south-western Arabia. This article, published in the National Museum’s journal Indago, documents the occurrence of 10 species of egg-eating snakes in this region, and discusses variation in their appearance, scale characteristics and colour pattern. Three of these were described as new species. One of the new species, the Arabian Egg-eater (Dasypeltis arabica), has a distinctive pattern on the back consisting of a longitudinal series of dark rectangles interrupted at equal distances by whitish squares which are joined at the sides to dark markings. This snake is found only in the highlands of Saudi Arabia and Yemen, where it has evolved in isolation from other egg-eaters on the African continent. The authors also provide evidence that the poorly known Ethiopian Egg-eater (Dasypeltis abyssina) occurs throughout the highlands of north-western Ethiopia and part of Eritrea. Below these highlands, in northern Eritrea, another new species called the Cross-marked Egg-eater (Dasypeltis crucifera) was discovered. It is characterised by pale ‘X’ markings between the darker markings on its back (see photo below). A third new species, Taylor’s Egg-eater (Dasypeltis taylori), occurs only in arid areas of Somaliland and Djibouti. These snakes usually have large square or rectangular dark markings along the back. The article also provides colour photographs showing variation in colour pattern in some of the more common species. Dr Bates will continue his long-term studies on egg-eaters in other parts of Africa.

The article can be downloaded for free on the Museum’s website (see under ‘Museum Publications’). Hard copies can be purchased from the Museum’s library.
