rescue effort saves stranded 600-lb leatherback sea turtle

PROVINCETOWN, MASS. (Oct. 12, 2021) – A leatherback sea turtle is back in the ocean after three local organisations joined together to save the massive animal that stranded on Cape Cod.

On Sunday, Mass Audubon Wellfleet Bay Wildlife Sanctuary responded to a report of a live leatherback on a mudflat along the Herring River in Wellfleet. Bob Prescott, director emeritus for Mass Audubon's Wellfleet Bay Wildlife Sanctuary, says he and volunteers worked to keep the leatherback from drifting with the quickly incoming tide.

"We wanted to keep it off the oysters and keep it from stranding somewhere we couldn’t rescue it. If it got away, there was no telling where it would strand next,” Prescott said.

The organisation contacted colleagues at the International Fund for Animal Welfare (IFAW) and the New England Aquarium to help rescue the large turtle, which is estimated to be about five feet long and 600 pounds. The turtle, an adult male, was alert and responsive.

Responders agreed to relocate and release the turtle, transferring it to Herring Cove in Provincetown where Rescue and Animal Health staff from the Aquarium conducted a health assessment.

A successful rescue and release

“Our initial evaluation indicated that the turtle was very strong and in good body condition, and this helped us to decide that it was a good candidate for release,” said Dr. Charles Innis, director of animal health at the New England Aquarium.

Dr. Innis analysed a blood sample to assess the turtle’s health and gave the turtle injections of vitamins and a nonsteroidal anti-inflammatory drug (NSAID). Aquarium staff then placed small identification tags—microchip and metal band—on the turtle along with acoustic and satellite tags. The turtle was then released back into the ocean, with a crowd looking on and cheering the turtle.

The Aquarium is tracking the turtle with a satellite “pop-up” tag that will determine if it survives over the next 30 days. The acoustic tag will monitor the turtle’s migration patterns over the next five to 10 years.

“When working with stranded sea turtles in New England, it’s a rarity to have a turtle that is in such good condition. We suspect this leatherback got disoriented in the tidal flats of Wellfleet and we feel optimistic that it will survive, thanks to the collective rescue efforts of this fantastic group of colleagues,” said Dr. Kara Dodge, research scientist at the Aquarium’s Anderson Cabot Center for Ocean Life.

This has been a busy week for leatherback rescues. On Thursday, October 7, an Aquarium team, led by Dr. Innis and Dr. Dodge, responded to a leatherback turtle entangled in fishing gear off Cape Cod. The female turtle was successfully evaluated, disentangled and outfitted with two electronic tags that will allow researchers to assess survivorship over the next 30 days and track her migration patterns. Leatherbacks are among the most highly migratory animals on earth, traveling about 10,000 miles or more a year. The turtles will be in Massachusetts waters through the month of October.

“Our agencies work side-by-side on these shores, rescuing and protecting local species, so we jumped at the chance to help with responders, equipment and transportation,” said Kira Kasper, a biologist for the Marine Mammal Rescue & Research program at IFAW. “To safely move a stranded turtle this large, our specially designed heavy-duty transport cart, stretchers and mats were ideal—originally designed by IFAW for moving dolphins and other small whales.”
