An Alabama map turtle--but not one that I found!
Our destinations on Sunday were access points to the Tombigbee River and If we failed to find Alabama map turtles,
Graptemys pulchra) and northern black-knobbed sawbacks,
G. n. nigrinoda, there to continue eastward to the Alabama River where we would again try our luck.
Similar to the other sawbacks,
G, n. nigrinoda ranges from 3 to 8” in shell length. Males are only about half the size of the females. We had no trouble at all finding tis species on both the Tombigbee and, later, the Alabama rivers. On the other hand, the broad-headed Alabama map turtle, the second largest of this group with females nearing a 12” shell length, has proven tough.
When it was thought that the Alabama map turtle ranged from mid-AL to the Pearl River drainage in MS, I had no trouble finding them. But now that the western forms (the Pascagoula map and the Pearl River map) have become full species, I have had no luck at all in finding the real, remaining, population of the Alabama map turtle. This search was no exception—at least for me. I found none. But Jake scored again. He, after clambering 50 yards over an almost vertical rockface and teetering back and forth while photographing, actually got fuzzy pix of 2
G. pulchra in the river below his perch.
But another trip is forthcoming and the next time success WILL be mine (LOL).
Although expensive, the northern black-knobbed sawback is still available to the hobby.
The backward directed knobs are well defined on this example.
