What Donut Coral look like

Acanthophyllia deshayesiana, commonly known as Donut Coral, exhibits a distinctive morphology characterized by its large, solitary, and disc-shaped polyps that can reach diameters of up to 12 inches (30 cm) in optimal conditions. The corallite structure is robust, with a prominent central mouth surrounded by a series of radial septa that are often brightly colored, ranging from greens to browns, with contrasting hues that may include pinks and purples. This species displays minimal sexual dimorphism, as both sexes exhibit similar external features. Defensive adaptations include the presence of potent nematocysts within the tentacles, which can deliver a painful sting to potential threats. Unique morphological features include the ability to retract its tentacles fully into the corallite during periods of stress or low light, enhancing its survival in fluctuating environments.

Behavior & temperament

Acanthophyllia deshayesiana is primarily a solitary coral, exhibiting a sedentary lifestyle anchored to the substrate. It extends its tentacles primarily during the night to capture plankton and small zooplankton, showcasing a nocturnal feeding behavior. This species does not engage in aggressive interactions with neighboring corals but can exhibit territoriality when in close proximity to other LPS corals. The polyp extension can be quite pronounced, reaching several inches in length, and is often accompanied by a pulsating movement that aids in capturing food particles. Its stinging potential is moderate, capable of deterring small fish and invertebrates that may pose a threat.

Diet & feeding

Acanthophyllia deshayesiana is primarily a carnivorous coral, feeding on zooplankton and small fish larvae in the wild. In captivity, it requires a diet supplemented with meaty foods such as mysis shrimp and finely chopped seafood, along with occasional feedings of high-quality coral pellets.

Behind the name

The genus name 'Acanthophyllia' derives from the Greek words 'akantha' meaning 'thorn' and 'phyllon' meaning 'leaf', referring to the thorn-like structures of the coral's polyps, while the species name 'deshayesiana' honors the French naturalist and paleontologist, Henri Deshayes.
