Many people have seen Diamond Head or at least pictures of Diamond Head, typically as viewed from Waikiki. In those pictures, Diamond head looks like a long, low ridge. Well, it's not. Diamond Head is a cinder cone (as you would expect) and is really quite circular as this picture, taken from the top of Diamond Head, easily shows.
This used to be the Hawaii State Fish, the Humu Humu Nuku Nuku Apua'a. At least before the legislature de-instated it. They couldn't agree on a new fish (politicians!) so it will have to do for now. This shy humu humu (reef triggerfish, Rhinecanthus rectangulus) is ducking into a hole in the reef off of famous Diamond Head. He would go into the hole and, if I waited, would pop out to see if I was still there trying to take his picture. He would then duck back into the hole. Cute little guy.
