Sand Dollar Illustration - Marine Biology & Educational Resource #1964815 (License: Personal Use)

This minimalist black-and-white line drawing depicts a sand dollar’s dorsal side, emphasizing the distinctive petal-like ambulacral grooves forming a five-pointed star. The irregular circular outline reflects the natural edge of the echinoderm’s calcareous test, commonly found washed ashore on sandy beaches. The image captures key morphological features used in marine biology identification and teaching.

Used in educational websites, marine science curricula, nature blogs, or coastal-themed design projects where a clear, scalable vector-style representation is needed. Matches user intent for learning about echinoderms, beachcombing guides, or iconography.
