What Acan Echinata look like
Acanthastrea echinata, commonly known as Acan Echinata, exhibits a robust and distinctive morphology characterized by its thick, fleshy polyps that can extend significantly during the night or when feeding. The corallites are typically large and can reach a diameter of up to 2.5 cm, with a maximum colony diameter of approximately 30 cm. The coloration ranges from vibrant greens and blues to deep reds and purples, often with contrasting patterns that enhance its visual appeal. Sexual dimorphism is not pronounced in this species; however, individual polyps may exhibit slight variations in size and coloration. Acan Echinata possesses a unique skeletal structure with prominent septa and a well-defined columella, providing structural integrity and defense against predation. Its defensive adaptations include the ability to retract its polyps into the skeleton, and it possesses potent nematocysts capable of delivering a mild sting to deter potential threats.
Behavior & temperament
Acanthastrea echinata is primarily a solitary coral that exhibits a relatively sedentary lifestyle, with polyps extending to capture food particles from the water column. It is known to engage in aggressive interactions with neighboring corals, utilizing its nematocysts to compete for space and resources. The coral has a symbiotic relationship with zooxanthellae, which provides it with energy through photosynthesis, although it also relies on heterotrophic feeding, capturing plankton and organic debris. During the night, the polyps extend fully to maximize feeding opportunities, while during the day, they may retract partially to minimize exposure to intense light. Acan Echinata is generally considered to have a moderate temperament, but it can exhibit territorial aggression towards other corals.
Diet & feeding
Acanthastrea echinata is an omnivorous coral that primarily feeds on zooplankton and phytoplankton in the wild. In captivity, it requires a diet that includes high-quality coral foods, such as finely chopped meaty foods and specialized coral pellets, supplemented with regular feedings of zooplankton.
Behind the name
The genus name 'Acanthastrea' derives from the Greek words 'akantha', meaning 'thorn', and 'strephos', meaning 'twisted', referring to the thorny appearance of its corallites. The species name 'echinata' comes from the Latin word 'echinus', meaning 'hedgehog' or 'spiny', reflecting the spiny structure of the coral.
