Yellow Scroll Coral

The Yellow Scroll Coral (Turbinaria reniformis) is a marine (saltwater) invertebrate in the Dendrophyllidae family of stony coral. It is an animal, not a plant.

The Yellow Scroll Coral is usually yellow or yellowish-green. It is a laminar (plate-like) species that forms horizontal plates or shallow chalices (cup-shapes) with thick walls. The skeletal cups are called coralites. The plates form a stony skeleton. Polyps protrude from the skeleton. The polyps have a central mouth disc with eight tentacles around the circular disc.

It lives in colonies of many identical individual polyps.Onecolony measures about 100 centimetres (39 inches) wide. The polyps are small at about 1 centimetre (half an inch) in length.

It is native to the waters of the Indian Ocean and the Pacific Ocean (the Indo-Pacific region). It prefers reefs and lagoons in tropical waters. It lives in the soil at the bottom of the ocean.

It is a filter feeder. The polyps catch microscopic food, such as copepods.

Each colony is either male or female.

The male colony fertilizes the female colony, and the planula larvae drift in the ocean tide. The larvae settle on the seabed and develop into polyps and start secreting protein that forms its bony skeleton. 

The Yellow Scroll Coral is slow-growing and lives for over 50 years.
