A dead baby humpback whale washed up on the shore of Jones Beach State Park Thursday morning.

The whale is about 30-feet long and was spotted by passersby just before 9 a.m., east of Field 6 in the High Hill section of the Long Island beach.

Rescue workers from Riverhead Foundation for Marine Research and Preservation were on their way to the beach to examine the whale.

They are also expected to perform a necropsy on the mammal to determine its cause of death. The whale did not have any apparent signs of injury.

The location of the whale is near to the site where a stranded dolphin washed up ashore in West Gilgo Beach last week. That dolphin died a day later in one of the Foundation's tanks after being rescued.

While there is no explanation for the two deaths a few miles and a week apart, marine biologists don't think it has anything to do with the oil disaster in the Gulf. However, they caution, nothing can be completely ruled out yet.

"They do calf down in the Caribbean but they probably would have left mid-April," Riverhead Foundation Senior Marine Biologist Rob DiGiovani told PIX 11 News.

This is the second humpback to come ashore. In April, a baby beached itself in East Hampton and eventually had to be euthanized.

"It's sad. I think everybody has a soft spot in their hearts for whales especially humpbacks," said Annie McIntyer, of the Jones Beach Nature Center. "They're the ones that sing...they're the ones that breach."

Marine biologist will perform a complete necropsy on the animal to try and determine what caused it to die. However, it could take weeks or maybe even months before they know.

It's still not known what caused the baby humpback in East Hampton to strand itself.

While two whales and a dolphin may seem alarming, the experts say it's not out of the ordinary.

"We're still in what we consider an average number of animals for the year," said DiGiovani. "I mean there are a lot of variables associated with our strandings whether it be large whales or dolphins."
