Marty’s photo of the day #3961: Hello again from Athens, West Virginia. Tonight, at 7:00 p.m., I present “Around the World in 90 Minutes” at Concord University. Today’s photo is from my behind the scenes tour this past Saturday at the Tanglewood Nature Center in Elmira, New York. I am holding “Buffalo Bruuuce,” a short-tailed opossum. Although at first glance you might think this cute native of Brazil is a rat or a mouse, he is actually a marsupial with a prehensile tail.
