Longer than 69% of all species in Chelidae 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 shell length here runs from 155 to 950 mm. The solid rule is this animal. Every bar is a count of real species, and nothing on this figure is estimated.

Keeping one
5 ft 9 in × 2 ft 10 in(175 × 88 cm)
Minimum floor length × width, for one animal. Bigger is always better. The standard sets no height for turtles and tortoises.
The standard sizes this genus at 5 times carapace length, with the width half the resulting length.
For a third and fourth turtle the standard asks for at least 10% more floor area each, and 20% more from the fifth onwards.
Water depth is set against the animal's carapace width rather than its length, so no figure is given here. Dry-country tortoises need no water area, only occasional bathing; tortoises from wetter regions need a water dish.
Swiss law reaches the same 8 × 4 of carapace length for land tortoises, arrived at separately from the German gutachten.
Gutachten über Mindestanforderungen an die Haltung von Reptilien (Sachverständigengruppe tierschutzgerechte Haltung von Terrarientieren), German Federal Ministry, 10 January 1997, section 5. The standard states these are recommendations rather than binding limits.
Swiss Tierschutzverordnung (TSchV), SR 455.1, Anhang 2, Tabelle 5 — legally binding minimum enclosure sizes, which give every land tortoise 8 × 4 body lengths for two animals.
From this animal’s own carapace length of 14 in (350 mm), at 5 times it — how this is worked out.
Active animals measured in the wild averaged 79 °F (26 °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.
345kJ per day
Worked out for an animal of 4,478 g, the heaviest recorded for Parker’s Snake-necked 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.
