This pair of female Galapagos Sea Lions seemed to be posing for the cameras as they basked in the evening sun at water's edge. They are massive -- sea lions are the largest animal on land in the Galapagos. There are somewhere around 50,000 sea lions in the Galapagos, mostly found on its sandy beaches. They are well adapted to humans, and often are the first creatures to welcome tourists as they clamber ashore. This particular pair, which I photographed side by side in profile, one with its nose to the sky, the other with its nose to the beach, symbolize the hold sea lions have on the human imagination. We study this image and wonder what they must be thinking at this moment.
