[5] Despite reports that it can grow up to 1.8 metres (5.9 ft) in length and is the world's largest extant freshwater turtle, this maximum size and title is murky at best.

[11][12] A more realistic range of carapace length for this species is reportedly 70 to 100 cm (28 to 39 in) and it is one of about a half-dozen giant softshell turtles from three genera that reach exceptionally large sizes, i.e. in excess of 100 kg (220 lb) in mass.

[13] P. cantorii is an ambush predator and primarily carnivorous, feeding on crustaceans, mollusks and fish (although some aquatic plants may also be eaten).

[2] The Asian giant softshell turtle is classified as a Critically Endangered by the IUCN and has been forced out through habitat destruction, disappearing from much of its range.

[10][18] In the Philippines, a juvenile Cantor's turtle known as "cagot" appeared and was captured by a fisherman along the Addalam River, Cabarroguis, Quirino, Isabela.
