Apalone spinifera spinifera - Eastern Spiny Softshell

Taxonomy
Class: Reptilia Order: Testudines Family: Trionychidae
Taxonomic Comments: See species account
Species Comments: See species account
Identification
Basis for Records: A good quality photograph showing the side of the neck or the rear of the carapace should be sufficient to identify this subspecies. Location in the French Broad river basin in the mountains provides important supporting evidence.
Field Marks: The Eastern Spiny Softshell is distinguished by having a single dark line located along the rear edge of the carapace and by the post-orbital and post-labial stripes usually separated on the side of the head (Palmer and Braswell, 1995). In the Gulf Coast Spiny Softshell, there are two or more dark lines at the rear edge of the carapace and the lines on the neck are usually connected.

Distribution in North Carolina
Distribution Comments: This subspecies is restricted to the mountains in North Carolina, where it occurs in the French Broad River and its tributaries; one recent record may come from the Pigeon River drainage.

Status in North Carolina
NHP State Rank: S1
Global Rank: G5T5
Status in North Carolina: SC
Status Comments: Only a few records exist for the Eastern Spiny Softshell in North Carolina, but several recent observations confirm its continued presence in the state. As in the Gulf Coast Spiny Softshell, it is probably limited to sandy or muddy reaches of rivers and in North Carolina it appears to be confined to the French Broad River system. Its status as a reproducing population in that system needs to be confirmed.
