Common name: Starfish

Asteroidea, commonly known as starfish or sea stars, are a class of echinoderms recognized for their star-shaped body structure. These fascinating marine invertebrates are found in oceans all over the world, from tropical coral reefs to the cold depths of the ocean floor. Starfish are not fish, despite their common name, and they exhibit unique features that make them intriguing additions to marine aquariums.

One of the most distinctive traits of starfish is their radial symmetry, typically having five arms, although some species can have more. They possess a remarkable ability to regenerate lost arms, a process that can take several months, which is an adaptation for survival in the wild. Their skin is often covered with spines or a bumpy texture, which can vary in color and pattern, making them visually appealing to aquarists.

Starfish play a vital role in their natural ecosystem as both predators and scavengers. They feed on a variety of organisms, including mollusks, small fish, and detritus. In the aquarium setting, they require a well-established tank with stable water parameters, as they are sensitive to changes in salinity, temperature, and pH. It's important for hobbyists to ensure that their aquarium can support the dietary and environmental needs of these creatures.

In addition to their ecological role, starfish have a unique water vascular system that aids in locomotion and feeding. This system operates through hydraulic pressure, allowing them to move and manipulate their tube feet. This fascinating mechanism is not only a point of interest for marine biologists but also for hobbyists who enjoy observing the complex behaviors of starfish.

Before adding a starfish to your aquarium, it's essential to research the specific needs of the species you are interested in, as some can grow quite large and may not be suitable for all tank sizes. Additionally, care should be taken to avoid species that might prey on other aquarium inhabitants.
