EVERETT, Wash. – The Everett Marine Patrol says nobody has seen a gray whale that had been swimming at the mouth of the Snohomish River in Everett on Saturday.
It's not known if the whale made its way out to open water or has died.
A whale expert with Cascadia Research told KING 5 on Saturday that the whale was extremely emaciated. The researcher said in its extremely poor nutritional state, there was very little they could do.
Everett's Marine Patrol watched the whale on Saturday, concerned that boaters might get too close and harass or stress the whale.
"The problem is that we want to ensure the safety of the whale itself, it appears to be in some sort of distress, its not acting like a healthy whale," said Sgt. Robert Goetz.
"It just surfaces real slow, rolls back down, goes down very, very slow and several times its just sat on the top of water as it doesn't have any energy and doesn't want to go anywhere," said Jim Pulley with the Everett Police Dept. Marine Patrol.
Cascadia Research says so far this year, six dead gray whales have washed up on Washington's coast. All the whales appeared to be thin and undernourished, which is a common cause of death during their long migration. Experts say it is not unusual to have five to 10 whales die during the spring migration.
