Note that only some of CoralNet's labels have rates provided, and many of those labels only have rates provided in one region.
You can view all the rates CoralNet provides in CSV format here:
Rates are in units of kg CaCO3 m-2 yr-1. A rate above 0 means that the label's presence contributes to positive carbonate production (i.e., calcification). A rate below 0 means that the label's presence contributes to negative carbonate production (i.e., bioerosion).
CoralNet's calcification rates are derived from ReefBudget's data.
Colonies are composed of clusters of dozens of corallites connected at their bases; occasionally, adjacent cylinders are fused along heir sides. Corallites are cylindrical, usually about 2.0 mm high but occasionally up to 5.0 mm. Corallites are 2.0 to 4.0 mm in diameter, but occasionally up to 5.5 mm. Some corallites have a double wall so that there is a cylinder within a cylinder. Corallite walls up to 0.3 mm thick. There are 20 to 29 septa in 2 cycles. In some cases, septal development precedes that of the wall, and the distal portions of the septa are exsert above the wall. In other cases, wall development precedes that of the septa resulting in a highly inset calice. All septa are strongly dentate, the proximal dentations of the primaries merging with the columella. Secondary septa are a thin series of spines on the wall. The columella is usually well developed, composed of knobby, twisted, rod-like trabeculae. Septal dentations and columella are granulated. C. tenella colonies are distinguished from other ahermatypic tubular corals by their small corallite size and colonial, reptoid growth form.
