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)
“Recent studies that have investigated maternal satisfaction have found this to be a better prediction of mother-child interaction than work status alone. More important for the overall quality of interaction with their children than simply whether the mother works or not, these studies suggest, is how satisfied the mother is with her role as worker or homemaker. Satisfied women are consistently more warm, involved, playful, stimulating and effective with their children than unsatisfied women.”
—Alison Clarke-Stewart (20th century)
“The land is the host and humans merely guests.”
—Chinese proverb.
