Small specimens of this species occasionally wash ashore. It is a non selective detritivore that relies on ingesting sea floor sediment for its diet, extracting nutrients as it slowly moves forward in its burrow. It is capable of burying to 30cm deep.
Buried in coarse sand, in subtidal areas, to depths greater than 100 m.
Southern and eastern Australia, excluding Tasmania. Eastern Victoria, potentially near Port Phillip.
