PORTLAND, Ore. (KOIN) -- A northern right whale dolphin washed ashore on Manzanita Beach on Saturday.
Seaside Aquarium said the animal was a female and over 5 feet long.
It was taken to Portland State University where a necropsy was performed. However, preliminary results from the necropsy were inconclusive. More tests are being done to see if they can determine the cause of death.
According to the aquarium, right whale dolphins normally live farther south and in deeper offshore waters. Since 1995, the aquarium has only seen four of these dolphins.
The right whale dolphin is known to travel in groups of up to 2,000 individuals -- although they're more often found in social groups between 200-300. They're also seen with other cetacean species including Pacific white-sided dolphins, humpback whales and Dall's porpoise.
