September 24, 2018 — Gray and harbor seals have lured sharks in increasing numbers into Cape Cod waters, with tragic results, but the burgeoning seal population is taking a hit from viruses.
The National Oceanic and Atmospheric Administration has issued an unusual mortality event alert for both species of seal in the Gulf of Maine.
From July 1 to Aug. 29 (when the alert was issued) 599 seals were found dead (137) or ill and stranded (462) on New England shores. In the few weeks since that number has soared to 921. Most of those were in Maine (629), with 147 in New Hampshire and 125 in Massachusetts.
The dead or dying seals have been located mostly to the north but a couple were found as far south as Plymouth in Cape Cod Bay.
