Bank Reefs
Description
Discussion
Formation
- These reefs are built upward from the seafloor.
- A single species often builds these deep-water reefs up.
- Photosynthesis is not typically the primary energy source for this system.
Morphology and Ecology
- Coral forms into clusters that are often larger than similar coral formations such as patch reefs.
- Bank reefs have a high species diversity living in and around them as is typical for most coral reefs.
- These are unique in that they exhibit spur and groove patterns.
- Spurs are low ridges of coral.
- Grooves are the sandy bottom channels that separate the spurs.
- Consist of elkhorn, seafans, staghorn, sea whips, and brain coral.
Location
- Found at deeper depths than other coral formations at 20-60 feet down.
- An example of one such formation is off the central east coast of Florida. Here Oculina varicosa is known to form bank reefs from the sea floor.
