Neptune balls are round, compact bundles of a seagrass species called Posidonia oceanica, which is found in the Mediterranean Sea. A common name for Posidonia oceanica is Neptune grass, which is why they are given the name 'Neptune balls'. Anchored to the seabed, the plant's leaves fall off and gather together like some kind of underwater tumbleweed, forming loose spheres.
