LONG ISLAND, NY -- Update, 6:20 p.m.: The second whale — a live baby — that washed ashore on a local beach Sunday afternoon was euthanized, in large because of the lack of resources to handle stranded, wild whales.

Kim Durham, the rescue program coordinator at the Riverhead Foundation for Marine Research and Preservation, said the male pygmy sperm whale was still breathing when discovered in the surf on Napeague, about one mile down from where a dead finback whale washed ashore earlier on Sunday. Marine biologists decided to euthanize the young whale for several reasons.

"It showed signs of illness," Durham said, adding that the Riverhead Foundation had no tank available to rehabilitate it. "It was a very sad afternoon," she said. The whale, which was about 5 feet long and 150 pounds and believed to be a yearling, showed poor body condition. Durham said its body was "sunken in behind the neck," a place biologists assess whales. It also had skin legions, which can indicate infection, she said.

Pygmy sperm whales, young or old, are off-shore species and found in warmer waters. "They are not supposed to be this close to shore," she said. "It is rare to have a pygmy sperm whale beached, whether it was dead or alive." An adult pygmy sperm whale was discovered dead on the shore in West Hampton Dunes in May 2012. The 9-foot whale was underweight at about 800 pounds.

A big part of the decision to euthanize instead of rehabilitate, Durham said, is that Riverhead Foundation only has one 30-foot diameter tank at its facility at the Long Island Aquarium in Riverhead, which is currently being inhabited by a harbor porpoise. "We don't have the resources for it," Durham said. "We can't put two species together in one tank and also we can't admit a new species into a tank with another that is already being rehabilitated."

Had it been another harbor porpoise, as was initially reported, they may have been able to rescue it and house it in a smaller tank, Durham said.

The harbor porpoise the foundation is currently rehabilitating was rescued from Maine. The Riverhead Foundation is the only tank for such mammals from Maine to Florida. It was transported to the Riverhead Foundation on Oct. 25, and is doing "remarkably well." It's release is expected within the month. Sunday's occurances left many asking: Is it too much of a coincidence that two whales washed up in the same area?
