Assessment of its conservation status is difficult, as few fisheries separate the great hammerhead from other hammerheads in their reported catches. This species is listed as globally critically endangered on the IUCN Red List ...
Sea water, in theory, could be used to help a fire. But, its salty components can do more harm than good, which is why firefighters typically avoid using it unless absolutely necessary.
