The Noose

Sea Lion at La Jolla Cove, S California.

Note the ligature around his neck, likely from an irresponsibly-discarded rope or plastic.  It doesn't seem to be interfering much with a decent life, even though it has clearly been there for a long time as his neck grew around it.  
Human junk is often  deadly for wildlife. 

I took another image of a smaller, light-colored  sea-lion a few years ago, in the exact same place with the same type of noose. This may be the same critter.
