A male California sea lion estimated to be at least 10 years of age appeared on a private stretch of West Seattle beach this afternoon. After receiving a call from a concerned resident, NOAA contacted Seal Sitters who responded to the scene.

Photos and video were emailed to Fish & Wildlife’s expert biologist for analysis. The sea lion is determined to be underweight (excess skin folds); an adult male should weigh upwards of 1200 lbs in prime health. Other indications lead the biologist to believe that the sea lion could be in failing health. SS and beach residents will monitor him if he remains on the beach, but his extreme bulk creates problems as far as treatment for any illness. He was nicknamed “Big Roy” by Deborah, the reporting party. Please check this blog for updates on his condition.

Unlike harbor seals, sea lions are able to move very efficiently and quickly on land because they can use all four flippers for locomotion. Consequently, one should never approach too closely - and most especially if the animal is unpredictable due to disorientation and mental confusion.
