torteau (iou) and coral reef (sh)


torteau (iou)



torteau noun. . L15.
[Old French tortel, mod. French torteau large cake, from tourte from late Latin torta: see TORTE.]
Heraldry. A roundel gules representing a round loaf of bread.

coral reef (sh)




Ridge or hummock formed in shallow ocean areas from the external skeletons of corals.

The skeleton consists of calcium carbonate (CaCO3), or limestone. A coral reef may grow into a permanent coral island, or it may take one of four principal forms. Fringing reefs consist of a flat reef area around a nonreef island. Barrier reefs may lie a mile or more offshore, separated from the landmass by a lagoon or channel. Atolls are circular reefs without a central landmass. Patch reefs have irregular tablelike or pinnacle features. Smaller patches occur inside atoll lagoons; larger patches occur as isolated parts of any of the Other three reef categories, and they sometimes occur completely separate from Other kinds of reefs.
