description Encope grandis Overview
Encope grandis is an irregular sea urchin commonly described as a sand dollar and classified in the family Mellitidae. It inhabits shallow marine environments of the eastern Pacific, where its flattened body is adapted to living on or partly beneath sandy seabeds. Openings in its test, often called lunules or keyholes, distinguish it from many solid-bodied echinoids and influence how water and sediment move around the animal.

Are the openings in Encope grandis natural?
Yes, the openings are natural lunules and not damage to a shell. Encope typically has five marginal ambulacral lunules or notches plus one posterior anal lunule, for six major openings or cuts in total. [Lander University](https://lanwebs.lander.edu/faculty/rsfox/invertebrates/mellita.html)
Is a white Encope grandis sand dollar still alive?
A living sand dollar has tiny spines and tube feet, while the familiar white disk is the cleaned test left after death. The flattened body and lunules belong to the animal's Mellitidae anatomy, not to a manufactured ornament.
