What Acan Lord Coral look like
Acanthastrea lordhowensis, commonly known as Acan Lord Coral, exhibits a robust, encrusting morphology characterized by its distinct, fleshy polyps that can expand significantly during the night or under low light conditions. The maximum adult size can reach up to 12 inches (30 cm) in diameter, with individual polyps typically measuring between 0.5 to 2 inches (1.3 to 5 cm) across. This species displays minimal sexual dimorphism, as both male and female polyps appear similar in structure. Acan Lord Coral possesses a unique skeletal structure composed of corallite walls that are often adorned with intricate patterns and colors, ranging from vibrant greens, blues, and reds to more muted browns and grays. The coral's defensive adaptations include a potent array of nematocysts, which can deliver a mild sting to potential threats, and its ability to retract its polyps into the skeleton for protection. Additionally, the coral exhibits a distinctive morphology with a prominent central mouth and surrounding tentacles that can extend to capture planktonic food.
Behavior & temperament
Acanthastrea lordhowensis is primarily a solitary coral species, although it can form small colonies under optimal conditions. It exhibits a nocturnal feeding behavior, extending its polyps to capture zooplankton and particulate matter from the water column during the night. This species is known for its relatively aggressive nature, often competing with neighboring corals for space and resources through the use of sweeper tentacles that can reach out to sting adjacent corals. Acan Lords are generally sedentary, remaining fixed in one location, but they can exhibit limited movement through the expansion and contraction of their polyps. They also engage in symbiotic relationships with zooxanthellae, which provide essential nutrients through photosynthesis, enhancing their overall health and growth.
Diet & feeding
Acanthastrea lordhowensis is primarily a carnivorous coral that feeds on zooplankton and small particulate matter in the water column. In captivity, it requires a diet supplemented with meaty foods such as brine shrimp, mysis shrimp, and specialized coral foods to thrive.
Behind the name
The genus name 'Acanthastrea' derives from the Greek words 'akantha', meaning thorn, and 'strea', meaning coral, while the species name 'lordhowensis' refers to Lord Howe Island, the location where this species was first described.
