Once he sang "I Am the Walrus," but now Ringo Starr is lending his support to another beast.
The former Beatle posted a photo of a rhinoceros on his official site with the simple message, "Save the Rhinos."
Numerous rhinos are on the endangered species list, putting their future at risk.
Starr has aided a number of charitable causes over the years, most recently providing original art to Timberland's "Canvas That Cares" footwear initiative last fall to benefit WaterAid.
Starr's latest studio album, "Ringo 2012," was released in January and features contributions from Charlie Haden, Van Dyke Parks, Dave Stewart and others.
