SEASIDE, Ore. — It's not yet known what killed an endangered fin whale, but people can marvel at the large marine mammal as it decomposes on an Oregon beach.

"While it's sad, it's also super educational," Tiffany Boothe, assistant manager of the Seaside Aquarium, said Thursday of the rare sight, which she said is only the second dead fin whale that Oregon has seen in about 30 years.

Just don't touch it because it can carry diseases that can be transmitted to humans and pets, she said.

"Also, it smells," she said. "I don't know how to describe it. It smells like a dead whale."

The 46-foot male whale washed ashore at Sunset Beach State Park south of Warrenton on Monday morning. It was entangled in rope.

But before officials could examine the rope and investigate the type of fishing gear it was, someone took it off and took it away, Boothe said.

"It was a well-meaning person, because the animal was still in the surf and appeared to be alive," she said. "And so they thought they were helping to detangle a live animal."

While the rope entanglement was severe, the whale wasn't in it for very long and it didn't lead to its death. It will be several weeks before results from a necropsy done on Tuesday will reveal what caused the emaciated whale's death, Boothe said.

The whale will naturally decompose, creating a "huge nutrient boost for the local environment," feeding scavengers like eagles and ravens, down to little amphipods, Boothe said.

Letting it decompose shows a keener understanding of what to do in these situations than in 1970, when officials opted to use dynamite to blow up a dead whale that washed ashore in southern Oregon.

The exploding whale incident in Oregon in 1970 wouldn't happen now, Boothe said, noting how that solution blew huge chunks of whale carcass into the sky, and even smashed the roof of a car.
