My nickname in the martial art sport of capoeira is Lagartixa, which means "sand lizard" or "gecko" in Brazilian Portuguese. My mestre said I was like a gecko because my skin was so pale you could see right through it.
Geckoes are also unusual creatures in that they possess a working set of vocal cords. Geckoes are, to my knowledge, the only lizards with a voice.
Here's my voice.
