Scientists say some species of shark return to the same breeding grounds for decades at a time, and live longer than previously thought.
Some species of shark return to the same breeding grounds for decades at a time, and live longer than previously thought, scientists studying the animals off Florida say.
“This is the first example that has shown long-term use of a mating ground,” Whitney said. “To observe natural shark behavior in the wild is incredibly rare to begin with and to observe mating behavior is really unusual.” Members of the research team said they did not guess the same animals would continue mating at the site for years at a time. Of all the sharks returning to the site, nearly 60% were monitored for more than 10 years and 13% were monitored for more than 20 years.
