Longer than only 44% of all species in Emydidae anyone has measured.
The bar is the rank itself: its length is the share of the family this animal exceeds. The chart below is the family’s real spread, on a logarithmic scale because body length here runs from 115 to 600 mm. The solid rule is this animal. Every bar is a count of real species, and nothing on this figure is estimated.

Keeping one
No enclosure size is given here
The standard sets enclosure size for turtles and tortoises genus by genus, and this genus is not among the roughly sixty it lists. No figure is given rather than one borrowed from a different animal.
Active animals measured in the wild averaged 78 °F (25.5 °C).
Mean body temperature of active individuals measured in nature. A measurement of the animal, not a setting for a thermostat.
Feeding
A prey item should be no wider than the space between the animal's eyes.
Widely used across reptile husbandry references. The stated reason is that the gap approximates the width of the throat, so wider prey is associated with impaction. This is established practice, not a measurement.
186kJ per day
Worked out for an animal of 2,232 g, the heaviest recorded for Chicken Turtle — so it is the top of the range, not a figure for a particular animal. Weigh yours and the number will be lower.
An upper estimate, not a feeding target, and not veterinary advice. The equation covers only what an animal burns staying alive, so a growing, gravid or recovering animal needs more — and it was measured on wild animals, which move far more than one in an enclosure. Body condition and a vet who knows the species are what a feeding decision should rest on. Where this comes from.
What nobody knows
These are not gaps in our research. No scientific dataset records them for this species — and saying so is information you cannot get from a reference that simply leaves a field out.
