Response teams from the U.S. and Canada worked together to execute a plan to save Scarlet.
A Lummi Nation boat slipped live salmon into the water through a long tube device, hoping to entice Scarlet to eat.
Response teams served salmon to Scarlet from the back of their boat, but they're unsure if she ate any of the fish.
Live, farm-raised chinook salmon were dropped in the water for Scarlet to feed on. It's unclear if she actually ate any of the fish.
Response teams were poised for the right opportunity to collect breath and fecal samples from Scarlet.
Researchers used a long pole with a petri dish at the end to collect a sample of the air Scarlet exhales out her blowhole.
When Scarlet exhales, the bacteria in her breath sticks to the petri dish researchers held above her head.
Scarlet was spotted off the west side of San Juan Island near Lime Kiln Lighthouse on Aug. 11, 2018.
