What does it eat? In Singapore, those seen appear to eat long bristleworms. Elsewhere, it is said to hunt small animals living on the bottom of the sea, especially small crustaceans.

Human uses: It is economically important and marketed fresh, frozen and dried-salted.

Status and threats: It is not listed among the threatened animals of Singapore. But l
ike other creatures of the intertidal zone, it is affected by human activities such as reclamation and pollution. Over-fishing can also have an impact on local populations.
