The northern spiny softshell turtle (Apalone spinifera spinifera) is a subspecies of soft-shelled turtle in the family Trionychidae. The subspecies is native to the United States and can be found from Montana at the western edge of its range to Vermont and Quebec on the eastern edge. Introduced populations have also been found in Massachusetts, New Jersey, Arizona, and Virginia. [3]
Apalone spinifera spinifera has sometimes been used only to designate populations east of the Mississippi, while populations west of the Mississippi have been designated Apalone spinifera hartwegi. The subspecific name hartwegi is in honor of Dr. Norman Edouard Hartweg (1904–1964), who was a specialist in turtles and professor of zoology at the University of Michigan. [4] While some morphological differences exist between northeastern and northwestern populations, a phylogeographic study found little genetic support for a distinction between eastern and western populations and recommended both groups be simply referred to as northern spiny softshell turtles. [5] This designation is currently recognized in the most up-to-date taxonomic checklist. [6]
The Geoemydidae are one of the largest and most diverse families in the order Testudines (turtles), with about 70 species. The family includes the Eurasian pond and river turtles and Neotropical wood turtles. Members of this family are commonly called Leaf turtle.

The Cuatro Ciénegas softshell, also called the black spiny softshell, is a subspecies of the spiny softshell turtle in the family Trionychidae. It is found only in the Cuatro Ciénegas Basin in the Mexican state of Coahuila and it is considered critically endangered by the IUCN. The subspecies, along with its parent species, was formerly classified in the genus Trionyx.
Nilssonia is a genus of softshell turtles from rivers, streams, ponds, and lakes in South Asia and Burma. In many treatments, it is monotypic, with the single species Burmese peacock softshell. However, the supposed other genus of peacock softshells, Aspideretes, is more closely related to N. formosa than had been believed. They differ only in the neural plates between the first pleural scale pair of the bony carapace, which are fused into one in N. formosa and unfused in the others.

Pelodiscus maackii, commonly known as the Amur softshell turtle or the northern Chinese softshell turtle, is a species of turtle in the family Trionychidae. The species is found in the Russian Far East, northeastern China, Korea, and Japan. It is possible that the Japanese populations are the result of ancient introductions by humans. This aquatic species may attain a straight carapace length of 32.5 cm (1.1 ft).
