The Turtle on Your Bay Walk May Look Dead. Don't Put It Back.

WELLFLEET BAY · WILDLIFE

Cold-stunned sea turtles strand on Cape Cod Bay beaches from November to mid-January. Mass Audubon's five steps, and why each exists.

5 min read · A Celebrate Lower Cape spotlight

That's the first of five steps on Mass Audubon's Wellfleet Bay sea turtle page, under the heading "If You Find a Cold-Stunned Sea Turtle." It goes first because it cuts against instinct. A turtle lying still at the wrack line looks finished, and the water looks like where it belongs.

The page answers both halves of that. "Do not assume a turtle is dead," it says, and then: "turtles that appear lifeless are often still alive." The cold water is the reason the turtle is on the sand in the first place.

Below 55 degrees, the bay becomes a trap

By Mass Audubon's account, "many sea turtles swim north to feed in our nutrient-rich waters" in summer. In fall they need to get back south, and some can't. The sanctuary says young turtles become "trapped" by the hooked shape of Cape Cod, and that strandings begin when ocean temperatures fall below 55°F. Too cold to swim, they're carried ashore by onshore winds, "mostly along the shore of Cape Cod Bay," as a 2025 Mass Audubon release put it.

Most of them are juvenile Kemp's ridleys, which the sanctuary calls "the smallest and rarest of the sea turtles." Greens and loggerheads strand too. The state's Kemp's ridley fact sheet says most strandings of cold-stunned ridleys happen along Cape Cod Bay in Barnstable County, and lists the species as endangered under both the Massachusetts and U.S. Endangered Species Acts.

How many is a matter of the year. In its 2025 season review, the sanctuary reported that as of Dec. 18, 2025, rescuers had recovered 667 cold-stunned sea turtles, 573 of them Kemp's ridleys. A month earlier, on Nov. 20, the count had stood at 232, nearly 200 more than at the same point the year before.

The calendar depends on which page you read. Mass Audubon says strandings "mainly take place from November to mid-January." The Kemp's ridley sheet says they "typically occur in November and December." The state's broader marine turtles page goes earliest: strandings "can start as early as the end of October." As of Oct. 22, 2026, Mass Audubon's sea turtle page lists no 2026 count, and its most recent season news is from 2025.

"By grabbing only their shell"

The other four steps follow from the first. Each one is there for a reason, though the sanctuary's page doesn't always say which.

Step two is to "carefully move the turtle above the high tide line." Above that line, the next tide can't return the turtle to the water that stunned it. The same step carries a warning: "Never grab or hold the turtle by the head or flippers." The state's marine turtles page puts the rule the other way around: "By grabbing only their shell, carefully move the turtle above the high tide line."

That's a rule about how to touch a turtle, which is the opposite of a rule against touching one. The agencies want it moved, carefully, by the shell.

A blanket of wrack, never sand

Step three is to "cover it completely with seaweed or wrack," the page says, and then, plainly, "never cover it with sand." The instruction comes without its reason. A 2016 Smithsonian piece supplied one, describing Bob Prescott, then director of the Wellfleet Bay sanctuary, as he "covers it in seaweed to shield it from the wind."

Step four is to "mark it with an obvious piece of debris like buoys, or driftwood, or draw a big arrow in the sand." Under a layer of wrack, a turtle is hard to tell from the rest of the wrack line. The marker is for whoever comes to get it.

Strangers with a federal permit

Step five is to "call the Wellfleet Bay hotline at 508-349-2615, Option 2, to receive further instructions." The call is the step that keeps a helper from doing more than the first four. The 2025 release notes that these turtles fall under the federal and state Endangered Species Acts, and that "it is illegal to interfere with them in any way without a permit."

The people who answer have one. Mass Audubon's patrol volunteers work under a U.S. Fish and Wildlife Service permit, according to the same release. "Since 1979," the project page says, "Wellfleet Bay staff and an annual corps of over 200 trained volunteers have patrolled the beaches of Cape Cod."

From the beach, the page says, staff bring the turtles to the Wellfleet Bay sanctuary to stabilize, and volunteers then drive them to the New England Aquarium in Quincy or the National Marine Life Center in Buzzards Bay. Most, by the sanctuary's account, "will eventually be released back into the wild."

The next date on the sanctuary's turtle calendar is Saturday, Nov. 7. At 10 a.m., a patrol meets at Crosby Landing Beach in Brewster to scan the wrack line at high tide. Its listing makes no promise: "Sea turtle rescues are never guaranteed."
