Distinctive traits:

DL9104 has a few small white spots on the left side of its peduncle, behind the dorsal ridge. It is not known what causes these light spots on belugas’ already white skin.

Viewed from the right, DL9104 shows a teardrop-shaped spot near its blowhole. Below that is a scattering of several white scars. Some of them are shaped like a microoganism called an amoeba.

Since this beluga has spots on both sides, the research team dubbed it “Deuxmino”, a nod to the popular tile-based game and the fact that another beluga is already named Domino.

Her/his story

The young beluga DL9104 has very unusual skin. Its whitish spots caught the team’s attention in 2019. Its still grey skin (belugas turn completely white around the age of 12 to 16) and small size suggest it was between 5 and 7 years old when it was first identified.

At the time of this first encounter, DL9104 had many teeth marks on its back. Belugas use their teeth in their social activities. Their way of giving their friends a good back scratch? Demonstrating their dominance? A form of play? We don’t know yet, but perhaps DL9104 will teach us about social interactions in young belugas and the role they fill in their development. However, we know that these scars disappear quite quickly.

Is DL9104 a male or a female? The answer should come soon: on October 2, 2019, the GREMM team took a biopsy – a tiny sample of fat and skin – which should reveal not only the animal’s sex, but also its lineage, contaminant levels and perhaps even its exact age.

DL9104 is observed in groups of both adults and juveniles, and sometimes with calves. How DL9104’s story unfolds will help us better understand the social and reproductive lives of belugas. By better understanding how belugas live, we will be able to better protect them.
