Leiaster coriaceus

Leiaster coriaceus is a benthic sea star found in the Indo-West Pacific region. This species typically inhabits hard rocky substrates and is associated with coral communities. It can be observed at depths ranging from 0 to 52 meters, with most occurrences recorded shallower than 40 meters. Divers may encounter this sea star in various habitats, including coral reefs and rocky reefs, where it blends into the environment due to its morphology. The sea star has a distinctive appearance, characterized by its stubby arms that develop as it matures from planktonic larvae into juvenile forms. Leiaster coriaceus is a deposit-feeder, primarily consuming organic matter found on the seafloor. Its feeding habits contribute to the ecosystem by recycling nutrients within its habitat. The reproductive strategies of this species include both sexual and asexual methods, with embryos hatching into planktonic larvae before metamorphosing into juvenile sea stars. This dual reproductive strategy allows for adaptability in various environmental conditions. Encounters with Leiaster coriaceus during dives can be intriguing, as they often rest on rocky surfaces or among corals. Divers should approach slowly to observe their behavior without causing disturbance. The conservation status of this species is currently not evaluated, indicating a need for further research to understand its population dynamics and potential threats.
