White Fluked Humpback Whale

A humpback whale flukes up in Exmouth Gulf, Western Australia.

The top fluke surface is usually black.  This is the first all white flukes we have seen in 
photographing 1480 humpback whales since 2006 in Exmouth Gulf.  This image was 
taken in October 2011 during the annual southern migration of humpback whales along 
the Western Australian coast.

Fins, Flukes & Photographs - Fingerprinting Humpback Whales



A humpback whale calf breaches in the protected waters of Exmouth Gulf, Western Australia.

Next month Pam and I will haul our 6.3 metre Gemini Inflatable 1300 kilometres up the North Western Coastal Highway to Exmouth to photograph the 2011 humpback whale migration and hopefully add another 400 or so whales to the identification catalogue.  Each fluke and dorsal fin is different and a unique 'fingerprint' for that whale.

In 2010 we travelled 671 NM on the water and observed 526 whales in 215 pods.  After allowing for  known re-sights, we saw 483 whales and photographed 444 of them.  164 were new season calves.  

We have been travelling to Exmouth each year since 2006.  Our first trip was to SCUBA dive and we accidentally stumbled across the best place on the planet to photograph humpback whales - Exmouth Gulf.

From August through to October each year the gulf fills with humpbacks on the southern leg of their migration from the Kimberley to Antarctic waters.  They have travelled 1200 kilometres from the Kimberley birthing grounds and calves are about 4 weeks old. The mothers and calves tend to congregate along the western shoreline from Bundegi Reef past the marina, along Pebble Beach and further south.

The shallow north facing waters of Exmouth Gulf provide an ideal rest and respite sanctuary for the world's largest population of humpback whales.  Here the calves can rest and build endurance before the arduous journey ahead.

Ningaloo Reef sits just around the corner from Exmouth Gulf.  Its inclusion in June 2011 as a World Heritage Area was well deserved but the critical resting areas in Exmouth Gulf were excluded.

Exmouth Whale Survey

Pam and I have completed our 2009 photo-id survey of humpback whales in Exmouth Gulf, Western Australia. We travelled 462 nautical miles, sighted 169 pods and 417 whales during 3 weeks in September. We were able to photograph 378 whales including 92 mothers with calves. The images have been processed and will be added to the Centre for Whale Research's database for this Humpback population.
