Before I moved here, I'd never seen a Goanna or Lace monitor . During the Summer months they patrol along the fences searching for rabbits . Some of them are over 4 feet long . I witnessed one go down a rabbit warren and emerge with a rabbit in its mouth , the rabbit dissappeared down its throat . They usually climb a tree when a human approaches but sometimes they just look at you
They have a venom in their mouth , only recently discovered . Mike
