Thank you so much for your comment. I will post more but let me share a group you might enjoy, it is a Flickr group titled Nature in the Philippines which has much many more photos .

A trip like that has been on my bucket list. Now age has crept in and it will not happen. I particularly enjoyed the colorful urchins in #5 and the volute in #8. Thank you so much for posting some of your memories. I would like to see more. My husband was stationed in Guam for nearly 3 yrs. and I fell in love with the warm, crystal clear water inside the reef. That was 1963 and I still miss the island as it used to be.
