[2][3] C. rossignonii has a big head, lengthy tail, pointed snout, and a coarse carapace with three easily seen ridges.

[2] The natural habitats of C. rossignonii are slow-moving freshwater rivers, swamps, tributaries, and wetlands.

[7] It is believed to be an omnivore that forages for an assortment of prey, including crabs, frogs, fish, and shrimp, as well as some plant material.

It is threatened by habitat loss and overharvesting for food by poorer communities, who are indiscriminate in the turtle species they harvest.

[1] A captive breeding program has been established in order to help the species gain population.
