A lone sea lion

Is it a log or a sea lion? As we came out onto Allan's Beach in the Otago Peninsula we could see something on the sand, but could not make out what it was. We discovered it was a sea lion, but was it alive? Sharon and Aphrodite strode closer to it as it appeared this creature was not breathing or moving...... they were going to give it a prod (brave souls), but then the sea lion's stomach took a deep breath, opened its eyes and yawned! Humpf tourists, it probably thought, then snuggled back into the sand and went back to sleep.
