Distinctive traits

With two deep scars in his dorsal crest, Ultra is easy to identify. The scar located on the hind portion of his dorsal crest has changed a few times between 2007 and 2009.

Life history

When we first encountered Ultra in 1992, he was already entirely white. Belugas fade from gray to white in colour between the ages of 12 and 16. Ultra would therefore have been born before 1980.

His sex was confirmed by genetic analysis of a biopsy taken in 1994 : Ultra is a male. In fact, this was one of the very first biopsies taken from a free swimming beluga. Ultra paved the way for an important research program that continues to this day and which has enhanced our knowledge not only of belugas’ social lives, but also of their diets and their exposure to contaminants.

Like other adult bulls of the population in summer, Ultra spends most of his time in herds composed essentially of males. Three networks of males are known : two of these navigate the Saguenay Fjord and the head of the Laurentian Channel, while the third one, the “Downstream Boys”, also uses the head of the Channel as well as the downriver portion of the Estuary, but avoids the Saguenay. Ultra has never been observed in the Saguenay to date. This is also the case for Louveteau and Marinis, two other males with whom Ultra is regularly spotted.

As the years pass by, males have a tendency to form stable groups of companions. These associations are established gradually and may play a role in belugas’ reproductive lives.

How Ultra’s story unfolds will teach us volumes on the evolution of belugas’ social lives. By better understanding how belugas live, we will better be able to protect them.

Under dark clouds and surrounded by a fine mist, we observe DL0058 at the mouth of the Saguenay. He is in a herd of about 60 individuals. Despite working conditions made challenging by the weather, we count five large groups of ten or so individuals. The animals head toward the Prince Shoal Lighthouse, which dominates the mouth of the Saguenay Fjord.

Then, after spotting a porpoise carcass, we must briefly interrupt our photo-ID work. We immediately contact Marine Mammal Emergencies (1-877-722-5346), but the carcass is not very fresh and has already begun to decompose. The Parks Canada team nevertheless decides to recover the animal and will investigate the cause of mortality.

The morning of September 16, 2009, DL0058 was spotted with Louveteau in a herd of around sixty adult males between Tadoussac and Les Bergeronnes. During this encounter, we attempted to take a biopsy sample from Louveteau; we narrowly missed our mark. We will therefore have to wait to add a DNA sample to our collection from this companion of DL0058.

Manoeuvring a boat and collecting a biopsy from a moving target is no small task. With practice, we’ve managed to attain a success rate of over 80%. All the same, when we do miss our target, there’s always a feeling of disappointment on the boat. These data are invaluable and such opportunities don’t happen every day. There’s always next time!
