Blue whales have very long slender bodies with a relatively small dorsal fin located approximately two thirds the way along the body. They have a broad, flat head with a distinct raised single ridge leading to a large splash guard around the blowholes. Coloration is greyish-blue with mottled pigmentation. The blow is tall and column shaped reaching a height of up to 10-12 m. Two types of blue whale are found in Australian waters; the pygmy and Antarctic. The pygmy blue whale is a subspecies and is the most commonly sighted in Australian coastal waters.
