North Beach Harbor Porpoise

Posted on May 30, 2016

Yesterday afternoon, our Marine Mammal Rescue Team responded to a recently deceased weanling harbor porpoise on North Beach. This calf was very small and emaciated, therefore it likely died as a result of failure to thrive after weaning from its mom.

Remember, if you spot any marine mammal on the beach, dead or alive, please call our 24 hour hotline: 603-997-9448. We collect important information at each response.
