Cagle's map turtle
Template:Short description Template:Use dmy dates Template:Speciesbox
Cagle's map turtle (Graptemys caglei) is a species of turtle in the family Emydidae. The species is endemic to Texas, where it is native to the Guadalupe, San Antonio, and San Marcos Rivers.[1]
Etymology
The specific name, caglei, is in honor of American herpetologist Dr. Fred Ray Cagle (1915–1968).[2]
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 Template:Cvt straight carapace length, while females can exceed Template:Cvt in straight carapace length.[1]
Diet
Adult females of G. caglei feed mainly on molluscs, but males and juveniles feed mainly on aquatic insects.[3]
Reproduction
Like all turtles, G. caglei is oviparous.[4] A sexually mature female may lay up to three clutches of eggs in a year.[3] Clutch size is small, only one to six eggs.[3]
