Female California Sea Lion with Severe Fishing Line Entanglement Injury, in the Coronado Islands, Baja California, Mexico. The line is buried in the sea lion's tissue so far that is difficult to see. It is possible this synthetic line will continue to cut into the skin of this sea lion until it succumbs to infection or blood loss. I have never seen any marine mammal rescue teams at the Coronado islands and suspect this poor animal will not live long.

A bull sea lion shows a brand burned into its hide by the Oregon Department of Fish and Wildlife, to monitor it from season to season as it travels between California, Oregon and Washington. Some California sea lions, such as this one C-704, prey upon migrating salmon that gather in the downstream waters and fish ladders of Bonneville Dam on the Columbia River. The "C" in its brand denotes Columbia River. These sea lions also form bachelor colonies that haul out on public docks in Astoria's East Mooring Basin and elsewhere, where they can damage or even sink docks.
