Galapagos Back-Scratch

Galapagos Sea Lions (Zalophus wollebaeki) are found on virtually every sandy beach in the islands. Though closely related to the California Sea Lion (Zalophus californianus), they are endemic to the Galapagos. They are found on most sandy beaches, lying around like large dogs in wet suits (as on commentator puts it). Like all sea lions, they are differentiated from seals by the presence of external ears (visible here) and more extensive front flippers, which they use to move vigorously--and even run--on land.

This individual has been scratching his back extensively in the sand. Sea lions are absolutely fearless in the presence of humans--and juveniles are often extremely curious.
