Asterias forbesi can be found from low tide to a depth of about 50 meters along the majority of the eastern seaboard, from Maine to the Gulf of Mexico. This species integrates with closely related species, as is typical of the more specialized groupings of Asteroidea. On rocky or shelly bottoms, specimens are found alone or in sizable groups. Because it is a predaceous oyster-eating creature, this starfish is economically significant and has been the subject of in-depth research. This animal causes the oyster business to lose a lot of money every year. Along with oysters, the starfish also consumes clams, mussels, sea snails, dead fish, worms, and in some rare instances, other starfish.
It is known that starfish migrate at certain seasons, however, it is unclear what this migration looks like or how far it goes. This organism moves quite slowly, on average 6 inches per minute, according to observations of its locomotion. The isolated geographic distribution of this species, however, seems to suggest that the range of these creatures’ wanderings is quite small.
Like all other living things, starfish have natural adversaries. Cold and fresh water, different fish, gulls and crows, and parasites are a few of these harmful agents and natural enemies. The menhaden is undoubtedly the foe that causes the most damage to starfish. This fish only consumes the tiny aquatic organisms that float or swim in the water. Only once the sun has set are the starfish larvae safe from this fish. The scene involves a transformation procedure and attachment to a bottom-level object. The tiny algae and other small types of plankton make up the nutrition of the free-swimming larvae.
The starfish is vulnerable to parasite attack. The parasite organisms assault the starfish’s gonads, damaging the tissue and partially or completely rendering it sterile.

Starfish: Interesting Facts
Sea stars, also known as starfish, are exquisite creatures that come in a variety of colours, forms, and sizes. The majority of starfish only have five arms, but certain species can have up to 40 arms, giving them all a starlike appearance. The fascinating marine organisms, which are echinoderms, use their tube feet to move about. With the help of their unique stomachs, they can devour huge prey and regrow damaged limbs.
1. A Sea Star Is Not A Fish
Sea stars are not actual fish, even though they are generally known as “starfish” and live underwater. Like fish, they lack fins, gills, and scales.
2. Echinoderms Are Sea Stars
3. There Are Numerous Species of Sea Stars.
4. Sea stars come in roughly 2,000 different species.
5. A Sea Star Does Not Always Have Five Arms
6. Arm Regeneration in Sea Stars
7. The Armor That Guards Sea Stars
8. No Blood Is Found in Sea Stars
9. Moving with their tube feet, sea stars have eyes, and they eat by turning their stomachs inside out.
10. True starfish are all members of the Asteroidea class.
11. Sea Stars Can Reproduce in Two Different Ways
