Hexagonal coral-like structures with varied morphology

The objects resemble coral polyps, clustered in a hexagonal arrangement. They exhibit a gradient color scheme, transitioning from a dark purple base to a lighter green near the apex. Some polyps are perforated with oval apertures, while others present a smoother, rounded form. The individual structures vary in height and exhibit slight differences in shape, creating a textured, uneven surface across the cluster. These forms suggest a biological function, possibly related to filter feeding or providing habitat.
