Seven-Armed Coral Star

Aquilonastra anomala

Aquilonastra anomala is a distinctive sea star characterized by its seven arms, which can help differentiate it from other similar species. This star exhibits a benthic lifestyle, typically found in tropical waters of the Pacific Ocean. It inhabits various environments, including coral reefs and rocky reefs, at depths ranging from 0 to 37 meters. Divers may encounter this species while exploring these habitats, where it often blends into the substrate due to its coloration and texture. Feeding primarily on small invertebrates, Aquilonastra anomala plays a role in the ecosystem by participating in the benthic food web. The reproductive strategy of this species includes both sexual and asexual methods, with individuals capable of regenerating lost arms and reproducing through gonochoric means. After fertilization, embryos develop into planktonic larvae before metamorphosing into juvenile sea stars with stubby arms. An encounter with the Seven-armed Coral Star during a dive can be intriguing, as divers may observe its slow movements across the seafloor. As for conservation status, Aquilonastra anomala has not been evaluated by the IUCN, leaving its population status uncertain.
