Got some video but that's quite a big effort.
Was briefly frightened :) Thought i was being approached by a big heavy duty shark when out fishing on my sup today.......big fat body and tall floppy fin sticking out of the water. Turned out to be either a young leopard seal or a very big fur seal.........floating along on its side with one fin up in the air

:)
and probably humming a little "I'm a big bad shark" ditty
