Why are Guadalupe fur seals stranding?
Guadalupe fur seal are stranding alive and dead and are mostly weaned pups and juveniles (1-2 years old). Findings from the majority of stranded animals include malnutrition with secondary bacterial and parasitic infections.
All live stranded Guadalupe fur seals are being rescued by local marine mammal stranding network members and undergoing long-term rehabilitation at The Marine Mammal Center in Sausalito, California or SeaWorld in San Diego, California.
As part of the UME investigation process, an independent team of scientists (Investigative Team) is being assembled to coordinate with the Working Group on Marine Mammal Unusual Mortality Events to review the data collected, sample future Guadalupe fur seals that strand and determine the next steps for the investigation.
