Patch reefs
Patch reefs are structures that are separate from major coral reefs. Here, we encounter them on sandy or rubble substrates. They provide refuge for lots of juvenile fishes that have recently settled. When no predators are around, the little fish radiate out from the patch reef, to feed. However, when a predator swims by, the little fish rapidly contract their range, and stay close to the reef structure.
