His field marks
DL0370 is easily recognized by the staircase-shaped hind portion of his dorsal crest as well as by the deep scar on the right peduncle. The end of his dorsal crest has changed a few times over the years.
Ever since our first encounter with DL0370 in 1990, he has always been recorded as being white. Belugas fade in colour from gray to white between the ages of 12 and 16. DL0370 would therefore have been born before 1978.
His large size, habits and associations overwhelmingly suggest that he is a male. His sex was confirmed by genetic analysis of a tiny piece of skin (biopsy) taken from his back in 2000. DL0370 is affiliated with one of the two networks of males that ply the waters of the Saguenay Fjord and the head of the Laurentian Channel.
Within these networks, bulls form stable groups of companions. These associations may play a role in belugas’ reproductive lives. Faithful companions of DL0370 include DL0269 and Jetstream. Surprisingly, DL0370 and DL0269 are very rarely seen with any of Jetstream’s other faithful companions. In fact, the quartet formed by Jetstream, Frimas, Camério and Dance-Sea was one of the first groups to tip off researchers concerning the formation of clans amongst male belugas.
How the story of DL0370 and his companions 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.
