pebble stones on the sea beach on a warm summer day, the rolling waves of the blue sea with white foam
Castries, Saint Lucia, West Indies: Vigie Beach - rolled coral rocks, also known as coral rubble or coral cobbles, are fragments of coral that have been broken off from nearby reefs or fossilized coral formations. Over time, the ocean's waves and currents tumble these coral pieces, smoothing their edges and rounding them into pebbles and cobbles of various sizes. These coral rocks play a role in the beach ecosystem, providing microhabitats for small marine life and contributing to the beach's natural erosion protection.

The sea life at Little Manuk, a so called rocky islet, is very interesting. Bubbles escape through the sand and rocks in places. Apparently there is still some volcanic activity. Hard coral cover almost 80% and the stress resistance, recovery, and overall reef health and resilience potentials of this coral community are all high. \n\nIn the shallow areas – like this view – there are slopes with black sand and tumbled rocks covered by algal turf and small hard corals, including large rocks with attached corals between four and five metres depth, often table Acropora, here Isopora on the rock behind and Porites in front. \n\nPorites corals can withstand even very harsh conditions more than other genera. \n\nThere are some Damselfishes and a Sandperch in the background.\n\nLittle Manuk near Tayandu Island, Indonesia \n5°29'38.856 S 132°17'30.456 E at 5m depth
