 Crustose coralline algae, Raffles Lighthouse, 2001. Coralline algae is important to the coral reef ecosystem. Their calcareous form helps to cement the reef structure through encrusting on loose substrate. Additionally, they possess chemical signals encouraging the settlement of hard coral larvae and other reef organisms. |
