A minute later the female turned and escaped inland up the crevasse as the tide washed over both animals. The male remained near the lower entrance sniffing at the water streaming from the sea lion. The adult male fur seal was seen again on 5 July from 1115-1400 hours; the juvenile was not present. The male spent most of his time lying in the crevasse with the tide washing over him. He occasionally patrolled his territory, chasing away subadult California sea lions and investigating and attempting to herd female sea lions. On each day the seal periodically left his territory, swam offshore approximately 200 meters, and remained there for 30^45 minutes. During these episodes the seal continuously rolled in the water and groomed itself with its foreflippers or positioned itself vertically head down in the water with the hind flippers protruding above the surface. July 4 and 5 were unusually warm (29-32°C) with clear skies and light winds (3-5 kts). Although the male fur seal never showed signs of heat stress he spent much of his time either in the splash or in the surf offshore. The adult male was still present on 10 and 11 July. Although the crevasse appeared to be the center of his activity, his territory had enlarged to 2-3 times its previous size, displacing a neighboring sea lion's territory 20 meters westward. The sea lion male which had been defending an aquatic territory to the east of the fur seal on 4 and 5 July had disappeared; by 10 July the male sea lion to the.
