Interaction With Humans
The nurse shark is not widely commercially fished, but because of its sluggish behaviour it is an easy target for local fisheries. Its skin is exceptionally tough and is prized for leather; its flesh is consumed fresh and salted and its liver is utilised for oil. It is not taken as a game fish. It has been reported in some unprovoked attacks on humans but is not generally perceived as a threat. Divers have often provoked the shark, however, by grabbing a motionless specimen by the tail.
Juvenile nurse sharks are sometimes sold in the saltwater aquarium trade. However, since nurse sharks attain lengths in excess of ten feet they are far too large to be kept in home aquaria. In an article for Aquarium Fish Magazine, Scott W. Michael criticizes the ethics of aquarists attempting to keep species beyond their spatial and financial means. He also notes that most public aquaria are not interested in taking specimens that have outgrown home aquaria and that they should never be released into the wild.

Famous quotes containing the words interaction with, interaction and/or humans:
“UG [universal grammar] may be regarded as a characterization of the genetically determined language faculty. One may think of this faculty as a ‘language acquisition device,’ an innate component of the human mind that yields a particular language through interaction with present experience, a device that converts experience into a system of knowledge attained: knowledge of one or another language.”
—Noam Chomsky (b. 1928)
“Just because multiples can turn to each other for companionship, and at times for comfort, don’t be fooled into thinking you’re not still vital to them. Don’t let or make multiples be parents as well as siblings to each other. . . . Parent interaction with infants and young children has everything to do with how those children develop on every level, including how they develop their identities.”
—Pamela Patrick Novotny (20th century)
“...there is hope for a tree, if it is cut down, that it will sprout again, and that its shoots will not cease. Though its root grows old in the earth, and its stump dies in the ground, yet at the scent of water it will bud and put forth branches like a young plant. But mortals die, and are laid low; humans expire, and where are they?”
—Bible: Hebrew, Job 14:7-10.
