Cagle's map turtle (Graptemys caglei) is a species of turtle in the Emydidae family endemic to the United States.
Contents
Geographic range
It is found only in the Guadalupe, San Antonio, and San Marcos Rivers in Texas.[3]
Etymology
The specific name, caglei, is in honor of American herpetologist Dr. Fred Ray Cagle (1915-1968).[4]
Description
Cagle's map turtle has intricate patterns on the carapace and plastron, as well as serrated edges on the posterior of the carapace, as is typical of all map turtles. It is smaller than most map turtles, and very sexually dimorphic, with males reaching only 4 in (10 cm) carapace length while females can exceed 7 in (18 cm) in carapace length.[3]
