Like Salmon and Sea turtles, the female lemon sharks return to their birthplace to give birth, an almost 20-year Research conducted in Bimini in The Bahamas reports.
The ongoing project since 1995 that involved capturing, tagging, releasing and tracking of more than 2K baby lemon sharks brought in a noteworthy phenomenon of sharks returning to their native birth place when it’s their time of giving birth, U.S. researchers reported.
“We found that newborn sharks captured in the mid-1990s left the safety of the islands when they were between 5 and 8 years old,” researcher Kevin Feldheim of Chicago’s Field Museum said.
Despite their impressive travels, female lemon sharks always return to the same location where they were born to give birth
“Yet, despite leaving and visiting many other islands in their travels, these sharks ‘remember’ where they were born after a decade of roving, and are able to find the island again when they are pregnant and ready to give birth,” he said.
Such a long surmising project was supported by student volunteers, who came to Bahamas, effort to prove the speculation was true.
Spanning the behavior of lemon sharks for almost two decades have resulted in the confirmation of the female sharks’ ability to return back to their birthplace to give birth but the difficulty of keeping track of sharks from birth to maturity has made confirmation of the behavior a struggle, the researchers said.
Evidence that sharks utilize the same nursery areas across generations underscores the critical importance of preserving local nursery habitats and can provide strong input in designating inshore marine reserves that would protect sharks of future generations, the researchers said.
