Read our previous post on Sutro Sam for more. Thanks, Sean!
Edit: It seems Sutro Sam has moved on from his temporary home in the Sutro Baths, probably "because of a lack of food or because his hormones were kicking in and he was saying ‘its time for me to go find a mate,'" says Megan Isadore of the River Otter Ecology Project. We wish Sutro Sam the best in his travels!
