Description

HABITAT

They can be found anywhere from North Carolina to the Carribean. They are usually on the bottom of sand fields and shelly sediment with minimal seagrass (Hendler et al., 1995).

BEHAVIOR

They hide themselves just beneath the surface of the sand. They are able to rebury themselves within 6-12 minutes and when they are turned upside down, they are able to flip themselves over in about 1 hour (Hendler et al., 1995).
