Higher up are smaller pools in the black rock. These have grazing snails and sometimes even have live coral! It seems that under the right conditions, coral is even tougher than algae. The rocks were so hot that the limpets were almost being cooked alive.
|Most of the bottom of this tiny pool is covered by colony of hard coral. It has a touch of bleaching on one edge.|

The coast that I observed a few days ago is not that different to temperate coasts where algae dominate the swash zone. Under the water, algae cover the rocks and a few metres further out the rocks give way to sand flats. In this underwater rock garden, sea urchins are the gardeners.
