According to The Irish News, the seals named Hans and Albert had been with the sanctuary since the summer, when they arrived with various injuries.
However, by September both had put on weight and were eating by themselves, prompting Exploris staff to plan for their eventual release at Ballintoy Harbour last Wednesday (29 November).
In a techy twist, Hans and Albert have been microchipped so their progress can be monitored from shore over the next few weeks and months.
Also in the care of Exploris staff is a baby seal rescued from a rocky outcrop off Bangor in Belfast Lough in late October.
BBC News has video of the tiny white seal pup, which was suspected to have an injured hip and damaged flipper likely suffered during Storm Ophelia.
Another presumed victim of the stormy weather was a seal recovered from Dun Laoghaire’s East Pier on Hallowe’en.
The Irish Times reports that the marine mammal had sustained injuries to its face and rear flipper, but was said to be doing well in the care of volunteers from the Courtown Seal Rescue Centre in Co Wexford.
More recently, a number of stranded dolphins were successfully returned to the water off Achill Island by locals and volunteers on Tuesday 21 November.
Four common dolphins were reflected from Keem Beach, though a fifth was found dead on nearby rocks. The Irish Whale and Dolphin Group (IWDG) removed the carcass to determine its cause of death, as the Mayo News reports.
Back on the North Coast, BelfastLive says a six-metre whale carcass surprised locals at Runkerry Strand near Portballintrae on 24 November.
The find came just weeks after a much larger fin whale carcass was found on Arranmore off the Donegal coast, as previously reported on Afloat.ie.
