A dead humpback whale washed ashore in Long Beach, but experts say they're unable to determine how it died.

The nearly 30-foot humpback was found on the beach at Laurelton Boulevard on Friday.

According to the Atlantic Marine Conservation Society, the body of the mammal was too badly decomposed to determine how it died. Samples have been sent out for further testing.

This is the fifth humpback whale AMCS has responded to in New York state this year.
