A couple of video snippets from Hawaii.
Assorted fish and coral in Hanauma Bay. Last one is a parrotfish (uhu in Hawaiian) having a snack - listen and you can hear that beak crunching the coral! Later on he'll excrete the indigestible parts as sand. Why, where did you think the beach came from?
The view from Leahi (Diamond Head). Nice afternoon hike, steep but short.
