Commensalism and competition are used by common seahorses when there is a large population of the species living in coral reef ecosystems.
Commensalism is used by seahorses regularly in coral reefs. As a form of camouflage, seahorses wrap their tails around corals to hide from predators. This benefits seahorses by providing them with shelter and protection from predators. However, the coral does not benefit.
Competition is used when there are large populations of common seahorses who co-exist in a habitat that does not have enough Phyto-plankton to support them. When this occurs, seahorses are known to fight others who come close to their food source and in some cases, one population can die out due to the lack of
