Another dead turtle surfaces on SouthCoast


Another dead turtle surfaces on SouthCoast

The reports of dead leatherback turtles in SouthCoast has continued to rise with one reported at Salters Point in Dartmouth on Sunday.

Tony LaCasse, media relations director for the New England Aquarium in Boston, said staff from Mass Audubon in Wellfleet Bay were notified but the turtle was so decomposed they will get almost no data by examining it.

"It is like a piece of tissue. It's probably been floating around for weeks," Mr. LaCasse said.

Three leatherback deaths have been reported on SouthCoast's beaches so far this month. They include a 600-pound leatherback removed from Pico Beach in Mattapoisett on Sept. 9.

A decomposed leatherback was still lying on the sand at East Beach in Westport on Saturday after being reported about a week earlier. The highway surveyor said he wasn't aware of it and would make sure it was removed.

Mr. LaCasse said they had photographs of the East Beach turtle but could not say for sure how much it weighed because it was already so decomposed.

There were 14 confirmed deaths of leatherbacks in Massachusetts waters this season and 14 reports of sightings of dead leatherbacks in coastal waters. Mr. LaCasse said the number of offshore sightings can't be confirmed because boaters could be reporting the same turtle.

"This has been an exceptional year for dead leatherbacks," Mr. LaCasse said.

He said the sightings are "probably the highest that we're aware of ever." Many of the dead sea turtles have been too decomposed by the time they reach shore for the New England Aquarium or Mass Audubon to determine the cause of death.

When they have been able to make a determination, there are often signs that the leatherback has been hit by a sea vessel. Mr. LaCasse said it is impossible to tell if the vessel hit the turtle before or after it was dead.

Leatherback turtles are considered endangered in the Atlantic Ocean so it is "of great concern" when they wash up dead here, Mr. LaCasse said.

In July, a 500-pound female that was tagged from West Trinidad was found dead on Cuttyhunk Island. Dead leatherbacks were also found in July at Popponesset Beach in Mashpee and Ricketson's Point in Dartmouth.

Dead leatherbacks should be reported to the New England Aquarium at (617) 973-5200. A sick or injured turtle should be reported to the Provincetown Center for Coastal Studies at 1-800-900-3622.

They can weigh from several hundred pounds to a ton. Because of the the turtles' size, Mr. LaCasse said, "boaters are often surprised when they see them." The turtles may have come to SouthCoast waters this season to feed on sea jellies. Mr. LaCasse said a majority of them have already moved south and east with the change of weather.

The New England Aquarium does not remove the dead turtles. Mr. LaCasse said removal is the responsibility of the property owner, which, at beaches, is often the town.
