Human Interactions
When approached, the coffin ray tends to keep still in its place of concealment on the sea floor. As a result, many divers, swimmers, and bathers have been shocked after accidentally contacting it. While not life-threatening, the shock can be quite severe. The shock can still be perceived by a person pouring a stream of seawater on the ray. The coffin ray has no economic value. In 1883, Edward Pierson Ramsay noted that it was the only ray native to Port Jackson that was inedible. It is caught incidentally by commercial trawlers, but is hardy enough to usually be returned to the water alive. It is also caught in lobster traps and infrequently taken by spear fishers. As it remains common and widespread, the International Union for Conservation of Nature (IUCN) has assessed this species as Least Concern. It has been kept in public aquariums, but requires moving food.

Famous quotes containing the words human and/or interactions:
“Whenever we encounter the Infinite in man, however imperfectly understood, we treat it with respect. Whether in the synagogue, the mosque, the pagoda, or the wigwam, there is a hideous aspect which we execrate and a sublime aspect which we venerate. So great a subject for spiritual contemplation, such measureless dreaming—the echo of God on the human wall!”
—Victor Hugo (1802–1885)
“In our interactions with people, a benevolent hypocrisy is frequently required—acting as though we do not see through the motives of their actions.”
—Friedrich Nietzsche (1844–1900)
