Common name: Bat star

General information

The Bat Star, scientifically known as Patiria miniata, is a colorful and distinctive sea star found along the Pacific Coast of North America. Its vibrant hues range from red to orange, yellow, and sometimes purple, with a web-like pattern that adds to its bat-like appearance. This invertebrate is not only a visually appealing addition to the marine aquarium but also plays a role in the ecosystem by scavenging and keeping the substrate clean.

Care

Bat Stars are relatively hardy and can adapt to life in captivity if provided with a stable environment. They require a tank with plenty of live rock and a sandy substrate where they can forage for detritus and uneaten food. It's important to ensure that the aquarium is well-cycled and has stable water parameters to avoid stressing the animal. Bat Stars are sensitive to sudden changes in water quality, so regular maintenance is crucial.

Reproduction

In the wild, Patiria miniata reproduces by broadcast spawning, where males and females release sperm and eggs into the water column. In captivity, breeding Bat Stars is quite challenging and rarely occurs. However, they can regenerate lost limbs, and in some cases, a new individual can grow from a single severed limb.

Habitat

Bat Stars are commonly found in rocky intertidal zones and subtidal areas up to depths of 300 meters. They prefer cooler waters and are often seen in tide pools and on rocky substrates where they can find ample food sources. In the home aquarium, replicating their natural habitat with varied topography and hiding places can help promote natural behaviors.
