[MARMAM] A question about a marked fin whale at North Atlantic

Dear Marmamers,                            last week fishermen from Galicia (NW Spain) told us that they saw a whale around 10 - 12m length with a yellow label/mark at its back swimming to the North Atlantic. We can't confirm the identification of the species but as 15 days before a fin whale calve of more or less the same length stranded at the coast, we suppose that it could be also a calve or a juvenile of this species.      Somebody is using this yellow marks for the identification of fin whales or tracking them?      Thank you!      Cheers,                      Ángela Llavona     ________________________________   C.E.M.MA. www.cemma.org ________________________________
