[4] A 1988 study found that the densest population occurred in Quintana Roo, as the state had been subjected to less deforestation than Campeche or Yucatán.

Additionally, Creaser's mud turtle has a curved (as opposed to straight) seam between the scutes of the plastral hindlobe and those of the fixed mid-portion of the plastron.

[5] K. creaseri aestivates most of the year, during which they are buried underground, and are only active during the rainy season, which occurs in June through October.

[5] The species is primarily carnivorous, with observations of their feces showing they are composed mainly insect parts and snail shells, although palm seeds were also occasionally present.

[5] The species is highly aggressive for a mud turtle, and both adults and hatchlings will viciously attempt to bite upon capture.

Additionally, the strongly hooked beak that makes this species distinctive is likely not an adaptation for deeding, but for aggression.

[5] This species is threatened by deforestation (increasing evaporation thereby reducing the number of pools of water), as well as the use of wet lowland environments for agriculture.
