CAMANO ISLAND – Scientists are working to determine what caused the death of a gray whale found floating off of Camano Island over the weekend.

Cascadia Research Collective, state wildlife officials and others are conducting a necropsy on the marine mammal Monday.

The gray whale was spotted early Sunday morning off the west Camano Island.

The animal was towed Sunday night to a secure location at Naval Air Station Whidbey Island.

Susan Berta with the Central Puget Sound Marine Mammal Stranding Network says the whale is about 37 feet long, but other details weren’t immediately available.
