 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.
