Clownfish, also known as anemonefish.

Mutualistic Relationship: One of the most captivating aspects of clownfish is their symbiotic relationship with sea anemones. While the stinging tentacles of anemones are deadly to most other fish, clownfish have a special mucus coating that protects them. They live within the tentacles of the anemone, benefiting from protection while providing the anemone with food scraps and deterring potential predators.

Unique Colors: Clownfish are known for their vibrant and distinctive colors, which can range from bright orange to yellow, red, and even black. These colors not only make them visually striking but also serve as a form of camouflage within the colorful surroundings of the coral reef.
