Sand Dollar - Natural Marine Skeleton with Star Pattern #3867613 (License: Personal Use)

This sand dollar displays the characteristic test (skeleton) of a flat, burrowing echinoderm, with a central five-part floral pattern formed by petaloid ambulacral grooves. Its light beige coloration and smooth texture indicate it has been bleached by sun and surf after death. Five small, evenly spaced perforations line the outer rim-part of its respiratory and locomotive system in life.

Used in marine biology education, beach-themed decor sites, nature photography portfolios, and eco-tourism content; matches user intent for identification, coastal aesthetics, or science learning.
