Some sharks return to the same sites to breed for decades
By PATRICK WHITTLE
Scientists say some species of shark return to the same breeding grounds for decades at a time, and live longer than previously thought.
The scientists with the New England Aquarium found that nurse sharks returned to the waters off the Dry Tortugas in the Florida Keys to mate for up to 28 years.
They also say before the work began, the sharks were only thought to live for about 24 years, and their life span now appears to extend at least into their 40s.
The researchers published their findings in October in the journal PLOS ONE as part of a long-running study of shark breeding.
