Elle is sighted in the Saguenay Fjord in a herd of some thirty belugas, including adults, young and three calves. We also recognize DL0030, one of the most familiar belugas to our research team. In the course of this encounter, we observe a curious behaviour: two young belugas are swimming close to the surface in a figure-S pattern and spatting out water. Are they chasing prey?
To capture their prey, belugas suck them in. When they miss their target and come up empty, they spurt out water. Might it be an eel? Despite the paucity of direct observations, scientists have long believed that eels might form part of belugas’ diet, especially in the fall when the latter are migrating in the St. Lawrence.
