"My mother-in-law, Maria Christopher, took this photo of a Northern Water Snake swallowing a catfish at a stream in Chapel Hill. She said neighbors have been observing it for at least the past three years and a friend of hers named it Mrs. Herpes! It is extremely large for its species, more than 4 feet long. We used the Web site, www.herpsofnc.org to assist our identification."
