What Favites Flexuosa look like
Favites flexuosa, commonly known as the brain coral, exhibits a robust and convoluted morphology characterized by its thick, fleshy polyps that form a dense, irregular surface. The maximum adult size can reach up to 30 cm in diameter, with individual colonies often displaying a lobed structure. Sexual dimorphism is not pronounced in this species; however, variations in coloration can be observed, ranging from brown to green and yellow hues, often with contrasting lighter or darker patterns. Defensive adaptations include a well-developed mesenterial filaments that can be extended to deter predators, and its polyps possess nematocysts capable of delivering a mild sting. Unique morphological features include prominent valleys and ridges that create a distinctive topography, enhancing its ability to capture planktonic food and increasing its surface area for photosynthesis.
Behavior & temperament
Favites flexuosa is primarily a sessile coral that exhibits a relatively slow growth rate and is often found in shallow reef environments. It engages in both autotrophic and heterotrophic feeding behaviors, extending its polyps primarily at night to capture zooplankton and detritus. This species can form symbiotic relationships with zooxanthellae, which provide essential nutrients through photosynthesis. Favites flexuosa displays a degree of aggression towards neighboring corals, utilizing its stinging tentacles to compete for space and resources, particularly in crowded reef environments. Its polyp extension patterns are highly responsive to light and water movement, with feeding behavior peaking during dusk and dawn.
Diet & feeding
Favites flexuosa is primarily a heterotrophic feeder, capturing zooplankton and particulate organic matter in the water column, while also relying on photosynthetic contributions from its symbiotic zooxanthellae. In captivity, it thrives on a diet that includes finely chopped meaty foods, plankton, and specialized coral foods enriched with vitamins.
Behind the name
The scientific name 'Favites flexuosa' derives from Latin, where 'favus' means 'honeycomb' referring to its structure, and 'flexuosa' translates to 'winding' or 'flexible', describing the convoluted shape of the coral.
