Conservation projects to bring river otters back to their natural habitats have proven to be successful. One river otter that made headlines in San Francisco proved just how exciting it can be when river otters reappear. This is a photo of Sutro Sam hanging out on the seawall at the ruins of Sutro Baths. The now-famous river otter temporarily made his home in the pond and was the first river otter to be spotted this far south in the bay area in 30 years. His appearance is a sign that significant conservation efforts to improve riparian habitats over the years are indeed working.
