A northern bottlenose whale that was stranded off Long Beach on Tuesday was suffering from kidney failure when researchers found it, experts said.

Biologists collected samples and organs Wednesday from the whale, then euthanized as it was found "to be compromised and suffering," said the Riverhead Foundation for Marine Research and Preservation.

A necropsy to determine the cause of the whale's deteriorating health was completed at the foundation's labs in Riverhead Thursday, foundation spokeswoman Rachel Bosworth said.

Biologists found "excessive numbers" of parasites in the whale's kidneys that had caused abscesses and tissue death, she said. The parasites have been sent to another lab for identification. Bosworth said the kidney problems likely caused the whale to come so close to the shore.

While New Jersey has had northern bottlenose strandings, this was the first reported stranding of the species in New York.

These whales -- in this case a female around 14 feet long -- that can reach around 32 feet and weigh as much as 17,000 pounds, according to NOAA Fisheries. The largest of the beaked whale family, they're found in a wide range in the North Atlantic.
