Manatee spotted off Cape Cod: ‘It’s rare to have manatees this far north’
Move over sharks. The beloved sea cow is the one getting all the attention in town.
A manatee was recently spotted off the Cape, according to researchers who said it was the first confirmed sea cow sighting off the Cape in nearly 10 years.
The manatee — a species usually seen in warmer Florida waters — was spotted at the end of July off Mashpee near Popponesset Bay. The marine mammal was stranded for some time.
The International Fund for Animal Welfare reported that they’re working closely with the U.S. Fish and Wildlife Service and local partners to “monitor the situation and assess the animal’s health and behavior.”
“Manatee sightings in this region are uncommon, and we are grateful to members of the public who promptly reported the initial stranding,” an IFAW spokesperson said in a statement.
“Early information is key to ensuring the best possible outcome for any displaced marine mammal,” the spokesperson added. “The animal was able to return to deeper water without intervention that day and was later confirmed to be active and mobile, but I believe there have been a few more sightings since then.”
The last Cape sighting was in 2016 off Falmouth. The pregnant manatee was named “Washburn” following her sightings near Washburn Island.
She was rescued by IFAW, sent to Mystic Aquarium for rehab, and then she was transported to Florida for release. She was even tracked in the Bahamas.
“It’s rare to have manatees this far north, and the fear is that they will become cold stunned come cooler fall temperatures,” said Nadine Lysiak, research scientist in the New England Aquarium’s Anderson Cabot Center for Ocean Life.
The Gulf Stream is now extending farther north, as the Cape’s waters get warmer. This means an expanded habitat for manatees and other warm-water species, like hammerhead sharks and tiger sharks.
The concern for manatees in the north is they can’t survive in waters below 68 degrees, and water temps can quickly drop in the fall.
