It contains two extant species:[2] Both species were formerly considered subspecies of a single species, Amyda cartilaginea, but phylogenetic evidence supports both being distinct from one another.

An undescribed species is also known from Borneo.

[3] The fossil taxon †'Amyda' gregaria from the Eocene of Inner Mongolia has been tentatively placed in the genus Trionyx.

[4] When it comes to the eating habits of Amyda, considering its multiple species, they are known for being opportunist omnivores.

Their diet consists mainly of plants and fish.
