Body length across Geoemydidae

Longer than 74% of all species in Geoemydidae anyone has measured.

130 mmthe whole family, smallest to largest800 mm

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 130 to 800 mm. The solid rule is this animal. Every bar is a count of real species, and nothing on this figure is estimated.

Feeding

296kJ per day

Worked out for an animal of 3,767 g, the heaviest recorded for Reeves’ 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.
