I've only seen a few of the plain brown ones and the meat was available enough in Guam to get some at the local hole in the wall eateries. They were going extinct due to being neat looking, hard to breed and tasty...Bad trifecta for any species.

I saw so many "what the !#$@#$ is that" things in Guam I can not count them all. These crabs, a spider that was larger than my hand (not a tarantula), and a fish with an eyeball the size of a soccerball the fish was HUGE jump to mind.
