Suddenly a second huge male emerged from below, gently nudging us with his pectoral fin as he passed. We photographed his left pectoral fin, because the unique spot patterns there and behind the gills are the best way to identify it. After sending our photograph to Konservasi Indonesia as a contribution to their whale shark monitoring programme, we learned that he had first been sighted on 16 December 2021 and goes by the moniker WP-RT-0209.
