Lemon sharks return to their exact birthplace to breed
"We found that newborn sharks captured in the mid-1990s left the safety of the islands when they were between five and eight years old," explained Dr Kevin Feldheim, the A. Watson Armour III Manager of the Pritzker Laboratory for Molecular Systematics and Evolution at The Field Museum and the lead author of the study.
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," Dr Feldheim added.
