WORLD REPTILE DAY 21 OCTOBER
In Marloth Park we are fortunate to have an interesting array of reptiles. Many of them we can observe close-up around, and on, our homes โ like geckoes and rock monitors.
What distinguishes a reptile from other animals? They:
โข Are vertebrates, meaning they have backbones
โข Are covered in dry, scaly skin and/or bony plates
โข Are ectothermic, (โcold-bloodedโ) meaning their temperature is regulated by the environment
โข Lay eggs on land, with a few exceptions.
Many reptiles go into semi-hibernation during the cold winter months โ a state known as โbrumationโ. However, on mild days they may emerge to bask in the sun.
The southern African reptiles can be classified into three orders, each very different from the other.
๐๐ต๐ฒ๐น๐ผ๐ป๐ถ๐ฎ๐ป๐ have shells, and include tortoises, terrapins and turtles. In Marloth Park we have two types of tortoises, and terrapins, which are only found in fresh water. (Turtles are salt water animals.) The shell is an extension of the rib cage. In Marloth Park we see leopard tortoises and the rather more unusual Spekeโs hinge-back tortoise. This species is only found in north-eastern South Africa.
๐ฆ๐พ๐๐ฎ๐บ๐ฎ๐๐ฒ๐ are scaled, and include snakes, lizards, skinks, agamas, geckoes, chameleons, and monitors. Snakes are legless and the others have four legs, even though some have evolved to be very small. โAutotomyโ is the remarkable defence mechanism some lizards and geckoes have developed, whereby they can shed their tail and it โregeneratesโ. The detached piece continues to move, distracting predators. Look out for the remarkably long Yellow-throated plated lizard, often found around anthills.
๐๐ฟ๐ผ๐ฐ๐ผ๐ฑ๐ถ๐น๐ถ๐ฎ๐ป๐ are represented by our one species, the Nile Crocodile. Note that our dams DO have crocodiles so be very aware and do not walk close to the waterโs edge. Crocodiles have also often been seen crossing roads near the Crocodile River.
