This coral grew like shrubbery.

It was hard to believe that, all this was the product of an invisible insect, instead of being a miniature forest turned into pure white stone.

The scene was surpassingly beautiful; coral branches ran up to a height of eight or ten feet from the bottom, where they locked and wove together like vines.

Paul walked to the edge of this reef and gazed with delighted eyes into its liquid depths.

Schools of bright colored fish were swimming gracefully in and out through the delicate coral branches.
