Observing coral reefs within the wild typically reveals simply how dynamic these ecosystems are. I’ve written about this earlier than in fact, however I’ve turned up just a few pictures that present a reef within the Pink Sea busily regrowing. It’s attainable that aquarists won’t understand simply how a lot bulk corals can amass and the way a lot their progress is predicated on corals rising on different corals. In these pictures I hope to indicate you a bit of shallow reef I got here throughout within the Pink Sea that exhibits wholesome and vigorous progress of SPS corals rising over different species, alive and useless. Right here’s the reef flat, a number of Pocillopora and Seriatopora. This can be a exhausting location to achieve, given wave motion and storms. A number of meters deeper and barely simpler situations end in good progress of acroporids and Porites. Now, take a look at this formation. As soon as a big table-forming acroporid, it’s now a mass of competing colonies and even a tridacnid or two. Nonetheless, the survival of those corals is doubtful; because the formation’s weight and ‘sail space’ will increase, a superb storm or plain outdated gravity will ship these corals to the rubble zone beneath. That may carry new alternatives for species beneath and clarify why you typically discover remoted tridacnids on the substrate. Right here’s one other outgrowth that may sooner or later fall. In fact, the rubble that falls from the excessive progress areas of the shallows and props the reef up takes a very long time, however that is how the reef inexorably marches outward.
