What is a reef denizen?

Reef Denizens are marine organisms that inhabit coral reefs. They include a wide variety of plants and animals, such as fish, corals, molluscs, crustaceans, and echinoderms. These organisms are adapted to the specific conditions found on coral reefs, such as warm, clear water and high levels of dissolved oxygen. Reef Denizens play important roles in the reef ecosystem, such as providing food and shelter for other organisms and helping to maintain water quality.

Here are some examples of reef denizen:

- Clownfish

- Parrotfish

- Bluestripe pipefish

- Seahorses

- Nudibranchs
