Care
Leather Stars are not commonly kept in home aquariums due to their specialized dietary needs and large size. They are scavengers and predators, feeding on a variety of invertebrates and detritus. In captivity, they require a large tank with plenty of live rock and a stable, mature environment. They are sensitive to changes in water quality and require a well-maintained system.
Reproduction
Reproduction in Leiaster coriaceus is typically sexual, with individuals releasing sperm and eggs into the water column where fertilization occurs. They can also reproduce asexually through fragmentation, although this is less common.
Habitat
Leather Stars are found in a range of habitats from intertidal zones to depths of over 90 meters. They prefer rocky substrates and are often found in areas with strong currents. Their range extends from the Aleutian Islands in Alaska to Southern California.
