30 Years 30 Sperm whales

After thirty years of activity at sea (which enabled us to collect the longest data series of this kind) we have chosen 30 flukes of sperm whales and combined each one with a year. 

Is it the year you met? The year you were born? Or maybe when you met your first whale? Or simply you love that specific whale...


Choose one of the flukes, or your “special” year, make a donation, and you will get the customized certificate with a picture of your whale. The electronic certificate will be issued to your name, or you can dedicate it to someone

Minimum donation is 10€.
