Sutro Sam the otter is San Fran's newest resident

America's cities are home to more creatures than just humans. Most city-dwellers know even they have to put up with a certain amount of wildlife -- be it pigeons, rats, nutrias or what-have-you. But San Francisco has a special new resident named Sutro Sam. (Special because, unlike the previously mentioned critters, Sam is adorable.) Named after the defunct Sutro Baths, now part of the Golden Gate National Recreation Area, Sutro Sam is the first river otter to take up residence in San Francisco in nearly half a century.

"This otter is the first otter recorded in decades and decades in San Francisco, and as far as I know he is the only otter in San Francisco," Megan Isadore, co-founder of the River Otter Ecology Project, told the San Francisco Chronicle. "He's a beautiful animal, well fed. He appears to be perfectly happy and not afraid of people."

Local biologists are unsure where exactly Sutro Sam came from, but they all agree the enterprising otter has an excellent new home. His preferred food is goldfish. Once household pets, Sutro Bath has been a popular spot to dispose of goldfish, who grow to the size of carp in their new environment, the perfect snack for a gentleman otter like Sam.

But is Sutro Sam really here to stay?

"I don't know what's going to happen," Isadore told the Chronicle. "At some point I assume that pond could be fished out, but it isn't yet. I assume he will stay as long as there is food or his hormones tell him to go somewhere else."
