Nile Crocodile

One of their purposes in nature is to control the amount of catfish in the rivers and streams.

Without this control, rivers would soon be stripped of all vegetation without which, smaller fish, turtles etc. would not be able to survive.

A distance of up to twenty kilometres will be walked by them at night in search of another water hole or stream if their current one dries up.

Their favourite food is medium sized antelope which they kill by holding it underwater until it drowns and then they will break off large portions by shaking it about and swallow it hooves and all. One impala, for example, take approximately twenty eight days to digest and so they will not feed again will during that time.

Flap-necked Chameleon (Chamaeleo dilepis) Chamaeleonidae

This is the largest chameleon (genuses Chamaeleo) I have ever seen and took pictures of it on my hand so you can get an idea of its size. When I first picked it up, it hissed at me and turned itself black in order to scare me off, but did it? No, not until I got my pictures. LOL!! Although not considered endangered, chameleons are a highly threatened group - particularly the flap-neck chameleon which inhabits populated and agricultural areas. They have many natural predators which include arboreal snakes, larger shrikes and certain raptors. Like most birds and reptiles, there is only about a two percent probability of survival to adult breeding age. The chances of successful breeding are even less.
The greatest threat to their survival comes from human activities. Destruction of habitat for development and chemical control of their (insect) food species severely restricts their range. Traditional, cultural ‘taboo’ results in unjustified persecution. Veld (grass) fires are probably the greatest killer, from which they have no escape. Their natural instinct is to climb up from danger, which takes them into the hottest part of flames. There is very likely 100 percent destruction of chameleons in a hot burn. I put it into my fishtank to crawl about and out popped this cricket to hitch a ride on its tail. :) Would you look at those claws!! A good thing he is not larger than he was or he would most likely have dug a hole in my hand with those nail. (And I thought mine were bad!! LOL!!) They are very pre-historic looking but here he was hanging on to my finger for dear life. After a while he calmed down and slowly got used to me handling him and started turning back to his natural colour. These larger chameleons lay their eggs in the soft sand soil while the dwarf (about 14 species) give birth to live young.
