A young grey seal, affectionately nicknamed "635" by the Acmom, was observed basking on the banks of the Léguer river near Lannion, Côtes-d’Armor, on Tuesday, February 24, 2026. Passersby noted an unusual electronic device attached to the animal's back, prompting inquiries. Océanopolis has confirmed that this equipment is a tracking tag, a standard procedure for monitoring the seal's movements and well-being. The seal's presence so far upstream in the river surprised some locals, leading to a call to the fire department, though Océanopolis reassured the public that the situation was not cause for alarm.
