Blind Shark - Human Interactions

Human Interactions

The blind shark is basically harmless to humans, though it can bite if provoked and is difficult to remove, owing to its strong jaws and powerful suction. There are cases of blind sharks biting and holding onto divers' wetsuits even after they surfaced, and could only be removed by prying open the sharks' jaws. This species is one of the few sharks considered suitable for private aquaria, as it is hardy, grows to a small size, and has sedentary habits, though its nocturnal, reclusive nature make it difficult to observe. The blind shark has even been induced to breed in captivity, with the Sydney Aquarium having successfully maintained a breeding colony.

Commercial fisheries do not target or utilize the blind shark, as its flesh has a strong ammonia-like taste that is not easily removed. It is caught incidentally by prawn trawl and other fisheries off Queensland and New South Wales, though post-discard survival may be high due to its ability to tolerate being out of water. Small numbers of blind sharks are caught by recreational fishers, who regard them as a nuisance because its small mouth and strong jaws make removing lodged hooks difficult. It is generally too small to be susceptible to shark nets used to protect beaches. The impact of collection for the aquarium trade on this shark is unknown but not thought to be severe. The International Union for Conservation of Nature (IUCN) has listed the blind shark under Least Concern, as it remains abundant and the various pressures on its population do not seem to pose significant threats. Its range overlaps a number of current and proposed Marine Protected Areas (MPAs).
