If you go into <www.balix.com/travel/guide/chapters/about_bali/fauna.html> you will find in the fauna section under reptiles a line and a bit about alu's, I put 'alu indonesian lizard' into my search engine and this is the first one I looked at, no doubt there might be more sites with info in them, I am now interested to find out more about them so I will be surfing some more. Have fun.
