What makes the Indo-Pacific humpback dolphin unique?
Indo-Pacific humpback dolphins are slightly larger than snubfins, growing to 2–3 metres in length. They are usually pale grey, have a long, slender beak and a large, distinctive triangular dorsal fin.
Among those humpback dolphins found in Australian waters, the snout, forehead and dorsal fin whiten with age, resulting in a patchy or often freckled appearance.
