On 23 June 2010, a young female killer whale was reported to be swimming in the Dutch Wadden Sea; a rare event for this species with the last stranding in Dutch waters in 1963.
The animal was monitored and it became clear the animal was in some distress and with the permission of the Dutch government the cetacean rescue foundation SOS Dolfijn and employees from Dolfinarium Harderwijk rescued the animal and took it to a temporary holding pool at Harderwijk for assessment and treatment.
Morgan, as the whale was to be called, was clearly malnourished when it arrived with her weight around 430 pounds. However, there were no sign of any underlying disease. She was monitored and medical parameters such a blood chemistry were measured. She progressed well and was found to be more than a 1000 kg. in weight when weighed in March 2011.
