They have a wide depth range, occurring from the lower limit of the intertidal zone to the shelf edge at about 200 m water depth, inhabiting the subtidal, sublittoral, infralittoral, and deep zone of the oceans. This adaptable species is classified as neritic, thriving in coastal waters and the continental shelf.

This family is further categorized under the Order Carcharhiniformes, which includes a wide variety of sharks, and ultimately falls under the Class Elasmobranchii, which encompasses all sharks, rays, and skates.
