Apalone spinifera guadalupensis
(Webb 1962)
Colorado River, Travis Co., Texas. April 6, 2005.
I saw plenty of these turtles along the river walk that winds along the Colorado River running through downtown Austin. The one pictured here was the largest, about as big as they come. The Austin river walk is a great place for turtle-watching.
