South Asian river dolphin

Fair call. I had a look at the images and the back fin profile does fit (for the new suggestion). Also perhaps the nose/beak is a little short for this to be a river dolphin?

Hi Max, I got another id from Kerala and please go through it.

The Chinese white dolphin or Indo-Pacific humpback dolphin (Sousa chinensis)

Thank you Max for the id.

Great shots! I'm sure you could get the subspecies on this if you wanted. Take a look at the link above.
