In addition to Uno a group of 5 California Sea Lions rested in the water a short distance from Cove 1 shore. Usually they rest of the large mooring buoys off shore but a tug and barge chased them into the water while tying up to the buoy. Flippers raised out of the water is for thermoregulation as the flippers lose less heat in air then in the water...they can also absorb heat from the sun. Lots of divers were in the area and the sea lions moved off shortly after the divers went in the water. Once the tug activity ceased the sea lions were back on the buoy. A few sea lions remained on the barge during the entire operation, undisturbed by all the activity.
