Body length across Tropidophiidae

Longer than only 34% of all species in Tropidophiidae anyone has measured.

34% of 35 species are smaller66% larger
227 mmthe whole family, smallest to largest1,180 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 227 to 1,180 mm. The solid rule is this animal. Every bar is a count of real species, and nothing on this figure is estimated.

Feeding

A prey item should be between the same width as the widest part of the snake's body and about 1.5 times that width.

Widely used across snake husbandry references. An alternative formulation gives prey at 10-15% of the snake's body mass. This is established practice, not a measurement.

4kJ per day

Worked out for an animal of 26 g, the heaviest recorded for Taczanowsky's Dwarf Boa. — 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.
