Star Fish and Echinoid Fossils

Star fish, also known as sea stars, are marine invertebrates found in oceans worldwide. These echinoderms are instantly recognizable by their star-shaped bodies and radial symmetry, typically having five arms—though some species may have more. Star fish play a vital role in ocean ecosystems, feeding on molluscs and detritus. Unlike fish, they have no backbone, gills, or scales, and move using tube feet located on their underside. Known for their incredible ability to regenerate lost limbs, star fish are a fascinating subject in marine biology and popular in educational and aquarium displays. Whether in rock pools, coral reefs, or deep-sea habitats, star fish are key indicators of ocean health.
