Soft corals were the dominant type of coral cover within the bay (2.4% hard and 12.8% soft coral cover) compared to the outer Thousand Islands (28.3% hard and 6.9% soft coral cover). Soft coral abundances, photosynthetic yield, and ETS activity were highly correlated with key water quality parameters, particularly DIN and sedimentation rates.One type of coral found in the ancient marine layers of the canyon is the horn coral. This solitary coral lived on the sea floor, with the pointed end of its “horn” embedded in the soft sediment for stability and the wider end with a cup-like depression in which the animal lived. Corals have a polyp shape, similar to its relative the jellyfish.The coral reef itself is an ecosystem that has producers, consumers and decomposers; however, the coral polyps within the coral reef are known as primary consumers because they consume producers.

The colonies of different species take different forms, building exoskeletons (outer protective structures) similar to those of corals. Most colonies are attached to a structure such as a rock or submerged branch. Freshwater bryozoans' exoskeletons are gelatinous (like jelly) or …This is the first detailed study of coral-bryozoan symbiosis from the Silurian; all previous reports describe Late Ordovician, Devonian, or Cenozoic material. The lack of malformations and decrease in the size of bryozoan zooids near the rugosans suggest there were no strong negative effects of the rugosans on the bryozoan.
