The Subfamily Trionychinae is further organized into finer groupings including:
- Genus (11): Amyda · Apalone · Aspideretes · Chitra · Dogania · Nilssonia · Palea · Pelochelys · Pelodiscus · Rafetus · Trionyx
- Species: ZipcodeZoo has pages for 169 species and subspecies in the Subfamily Trionychinae.
Amyda is a genus of softshell turtle in the Trionychidae family. It contains the following species: [more]
Apalone is a North American genus in the Trionychidae family of turtles, a family whose members are commonly referred to as softshell turtles. Apalone species are native primarily to the United States, though they are also found in parts of southern Canada and northern Mexico. Apalone is a fairly new classification, resurrected by Meylan in 1987, assigned to North American species of the genus Trionyx, though they are still listed as Trionyx in some texts. (Trionyx now refers specifically to certain softshell species found mainly in Africa.) Apalone are fast swimmers that chase down their prey in water. They feed mainly on fish. They also like the comfort of sand as their bedding. [more]
Aspideretes is a genus of soft-shelled turtles (family Trionychidae). It has been found to be so closely related to the Burmese Peacock Softshell (Nilssonia formosa) that it is probably better united with this species under Nilssonia, the older name. They only differ in having two separate neural plates between the first pleural scale pair of the bony carapace, while these neural plates are fused into one in N. formosa. [more]
Chitra could refer to [more]
Dogania is a genus of in the Trionychidae family. It contains the following species: [more]
(L. palea: chaff) (pl. paleae) The upper, and usually shorter and thinner, of two membranous, chaffy bracts which subtend a grass floret, often partially surrounded by the lemma.
In polychaetes, a strong, broad, or flattened seta, usually associated with the operculum or the anterior part of the body.  [more]
Pelochelys is a of turtles of the family Trionychidae. [more]
Rafetus is a genus of highly endangered softshell turtles in the Trionychidae family. These large turtles are found in freshwater habitats in Asia. According to most taxonomists, the genus contains the following 2 species: [more]
At least 86 species and subspecies belong to the Genus Trionyx.
