Sand Dollar

Scientific Name: Unknown Species
Reef Compatibility: Yes

Minimum Tank Size: 75 gal

Max Size: 7”

Food/Feeding: Omnivore

Notes: Densely packed, tiny, often purple spines cover live sand dollars and hide the star design. In their sandy seafloor habitat, sand dollars use their fuzzy spines, aided by tiny hairs (cilia), to ferry food particles along their bodies to a central mouth on their bottom side. They capture plankton with spines and pincers (pedicellariae) on their body surfaces. A tiny teepee-shaped cone of spines bunched up on a sand dollar's body marks a spot where captive amphipods or crab larvae are being held for transport to the mouth. Unlike sea stars that use tube feet for locomotion, sand dollars use their spines to move along the sand, or to drive edgewise into the sand. On the upper half of the sand dollar's body, spines also serve as gills.
