Many of us have an unfounded fear of lizards and we will not go out of our way to see one but do take a look at the photographs of a beautiful Peninsular Rock Agama sent by Joiston Pereira, a visitor to the lake. Do show them to your children!
Visit the lake yourself and see if you can spot one. Be brave. It is not poisonous but could bite if you attack it! :-)
