There are almost 20 species of Pocillopora, but they all have the same characteristic bumpy branches, which can be densely packed or wide and spread out. ... (such as distance from a branch tip) however this brings into question the value of using morphometrics in the first place. At times you can even find branches going out of plates.

We cannot be held responsible for any errors on the site and for any actions you may take after viewing its content. You can identify Montipora via its small corallites, which are embedded in the surface of the coral. The branches can have smooth branch tips or pointed branch tips. This may happen, for example, if a larger colony is broken off from the main colony during a storm or boat grounding. The branches are delicate, so be careful when approaching or photographing this species. These photosynthetic organisms provide the coral with organic carbon and nitrogen, sometimes providing up to 90% of their host's energy needs for metabolism and growth. This is called an axial corallite and is unique to Acropora. Poor growing conditions, environmental stress, or other pathogen infections can weaken a tree or shrub and make it vulnerable to coral spot fungus. The living coral may be black, red, orange, brown, green, yellow, or white (depending on the species). The only living part of the coral is the soft bubbles at the tip of the branch.

If you are just learning to identify corals, Acropora is the best place to start. If the branch has uniform corallite sizes or multiple corallites on the branch tip you can confidently call it Acropora. The most abundant genus of branching corals is Acropora, with over 100 described species in the Indo-Pacific. All hard-coral species have corallites, but Acropora corals have one larger, distinct, tubular corallite on the tip of each branch. Anacropora is a relatively fast-growing species and often sprawls above the substrate, covering a large area. All hard-coral species have corallites, but Acropora corals have one larger, distinct, tubular corallite on the tip of each branch. The most popular colour? The Romans hung branches of coral around the necks of their children to protect them from danger. Brain corals, a slow-growing species of coral, often act as foundations for reefs.

Its remaining needs are met by the planktonic organisms caught by the tentacles of the polyps. Here’s our introduction to the branching corals of the Indo-Pacific. $6.00 .
