Serendipitous re-sighting of a basking shark Cerorhinus maximus reveals inter-annual connectivity between American and European coastal hotspots

A female basking shark Cetorhinus maximus was tagged with a satellite transmitter at Malin Head, Ireland and re-sighted 993 days later at Cape Cod, USA, a distance of 4632km.Transatlantic stock mixing in basking sharks is supported by low genetic diversity in populations throughout the Atlantic Ocea...

Description
Summary:A female basking shark Cetorhinus maximus was tagged with a satellite transmitter at Malin Head, Ireland and re-sighted 993 days later at Cape Cod, USA, a distance of 4632km.Transatlantic stock mixing in basking sharks is supported by low genetic diversity in populations throughout the Atlantic Ocean but this is the only record to date of transatlantic movement by basking shark despite significant focus on the species’ movements; > 1500 individual sharks tagged conventionally and > 150 individuals with remote tracking tags.
