Hello, I am an informal educator on the outer coast of Washington State. Several years ago I developed a popular hands-on program called Sea Lion CSI: student teams investigate 1/4-size California sea lion models to determine possible causes of death. I used the five most common causes of death in our region at the time - fishing net entanglement, gunshot, leptospirosis, urigenital cancer, and pneumonia. I'm expanding my program and would like to include a marine debris component. Fortunately, the only interaction with marine debris in our area appears to be packing straps getting caught around the sea lion's neck. And this typically doesn't kill them. Does anyone have data on marine debris interactions killing pinnipeds? Is it a significant factor in pinnniped health elsewhere in the world?
