POSITIVE SIGNIFICANCE: Food, Medicine. Comments: Used as a subsistence food on many island, used in medicine on Penrhyn.
NEGATIVE SIGNIFICANCE: Injurous spines - moderate

GENERAL NOTE: Traditionally this species was considered to be very variable, even including the black Echinometra oblonga as a subspecies. Leaving oblonga aside as a species, recent molecular studies have divided the remainder into three species: (1) with white-tipped spines; (2) unicoloured spines and abundant rod-shaped gonadal spicules in bundles; and (3) xxxxxxxxx.
