Unlike other sawsharks, the barbs on this shark's rostrum continue onto the sides of the head.

The sixgill sawshark is found in the temperate and subtropical waters of the western Indian Ocean between latitudes 23° S and 37° S, at depths of between 37 and 500 m. This shark lives in the benthic and benthopelagic zones of the continental shelf.

Adults are partially segregated from juveniles, as they naturally tend to aggregate at lower depths.

[3] Using their sensitive barbels and electric sense, sixgill sawsharks are able to find their prey and then incapacitate them with their rostrum.

Because of their deep habitat, sixgill sawsharks are not considered a threat to people.
