A male dolphin found stranded in East Hampton on Saturday was euthanized Sunday after his health deteriorated overnight, said a spokeswoman for the Riverhead Foundation for Marine Research and Preservation.
The dolphin was rescued off a private beach near Lily Lane after the foundation received a call reporting the stranded sea-mammal about 9:30 a.m. Saturday, said Rachel Bosworth, a spokeswoman for the foundation.
Two biologists and an intern arrived at the private beach at 11:30 a.m., and “determined the animal should be transported back to the foundation’s hospital facility,” Bosworth said.
The biologists said the dolphin, which weighed 268 pounds, appeared to be underweight, noting that most male dolphins weigh about 400 pounds.
The dolphin was tube-fed fluids to help rehydrate him, and placed in a special tank for marine mammals. Blood samples were also taken to determine if he had any other illnesses, but results for those tests were still pending.
On Sunday morning, the dolphin’s health continued to deteriorate — it was having difficulty swimming, and blood was found in its gastrointestinal tract — prompting biologists to euthanize the sea mammal.
“Unfortunately, it has been determined the most humane course of action is to euthanize the animal as it would likely not survive rehabilitation,” Bosworth said. “Following a consultation with volunteer veterinarians, the dolphin was euthanized and passed peacefully.”
