whales such as the Fin or Sei. This trait may be used by observers to differentiate between species at sea. Some Blue Whales in the North Atlantic and North Pacific raise their tail fluke when diving. When breathing, the whale emits a spectacular vertical single column blow (up to 12 m (...
Through January-April 2000 research was carried out off the Rottnest trench to search for blue or pygmy blue whales. A consortium of researchers carried out aerial surveys, boat based studies and acoustical measures. Historical records led us to believe that a Western Australian population of pygmy...

Eastern and western populations are known in the North Atlantic, and at least five populations have been described in the North Pacific. The population structure in the Southern Hemisphere is unclear. However, “true” blue whales must have different populations in the southern Indian, Atlantic, ...

"It's very exciting considering the fact that we've only seen blue whales four times in our 46 years of business," Douglas said. "Our naturalists who do this every day were literally crying on the deck of the boat when they saw it, so it does give you goosebumps." ...
Passive acoustic recorders set around Australia since 2004 have been used to study blue whales. Calls from New Zealand pygmy blue whales occur predominantly eastward of Bass Strait (145.8° E), calls from Eastern Indian Ocean pygmy blue whales (EIO PB) west of Bass Strait, while Antarctic blue...
In 2013, a hypothesis was put forward that blue whales (Balaenoptera musculus) use the South Taranaki Bight (STB) in New Zealand as a foraging ground for krill, specifically the euphausiid Nyctiphanes australis. This hypothesis was based on a desktop analysis of previously collected data and ...
However, none of the 84 whales photographed off ETP have been re- sighted within or outside of the ETP. In Perth Canyon, off Western Australia, twenty-three individuals of the 208 catalogued from 2000 to 2005, were resighted between years and only two whales were resighted in three or ...
Chile. Pygmy Blue Whales tend to be solitary although numerous animals are found in areas of high productivity particularly in the northern Indian Ocean, off Sri Lanka and southern & western Australia. The migratory behavior of Pygmy Blue Whales is variable with some populations considered resident ...
