This poor Marru was fatally hooked and drowned on a fishing line:

Factory fishing boats nowadays set very long lines—often fifty miles long—with thousands of baited hooks that float on the water and attract seabirds. Some boats abide by simple rules enacted to protect seabirds—attaching colorful streamers to the lines to warn us, or ensuring that the baited hooks are well submerged, or laying the lines at night. But many boats do not care and operate illegally; one hundred thousand albatrosses are killed every year by long-lines—a devastating number because we mature and reproduce so slowly. We Wandering Marru are facing extinction within two decades unless drastic change occurs.

Perhaps you humans could try to eat less seafood, maybe once a month instead of once a week. You should try to regard seafood as a rare treat rather than a routine right.
