His field marks

DL0242 can be recognized by the unique shape of the scar at the end of his dorsal crest, which is visible from both sides. The crest itself contains several small details. He also bears a gray spot behind his head on the right side.

Life history

We first encountered DL0242 in 1992. He was still gray at the time, but of considerable size. He turned white around 1997. Belugas fade from gray to white in colour between the ages of 12 and 16. DL0242 would therefore have been born around 1981.

His large size and habits suggest that DL0242 is a male. Like other adult bulls of the population, he 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.

Within these male networks, adult bulls form stable groups of companions. These associations, which are established gradually, may play a role in belugas’ reproductive lives.

DL0242 and his most regular companions – Stanley, Moby Dick and DL0238 – have rarely been observed in the Saguenay River. They probably belong to the “Downstream Boys”.

How DL0242’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.


DL0242 observations history

Latest news

  • AUGUST 9, 2011

    We’re off the coast of Les Bergeronnes. DL0242 is in a massive herd numbering some 150 belugas. The majority are white adults, clustered in groups of 5 to 8 individuals plus a few solitary animals.

    These large gatherings are short-lived in nature, and consist essentially of males. They are often observed in the downriver sector of the beluga’s summer range, namely between Tadoussac and Les Escoumins. After a few hours, these expansive herds separate into smaller groups.
