Body length across Pythonidae

Longer than only 8% of all pythons anyone has measured.

8% of 37 species are smaller92% larger
750 mmthe whole family, smallest to largest7,900 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 750 to 7,900 mm. The solid rule is this animal. Every bar is a count of real species, and nothing on this figure is estimated.

What is known

39 sourced facts, each taken from a named scientific dataset. How to read these.

Cited from a dataset unless a row is marked otherwise.

Two of these figures disagree

Length snout to vent (greatest recorded) is given as 1,320, and Length nose to tail (greatest recorded) as 1,259 — but snout to vent is part of the animal's total length, not more than it. They come from different sources and both are shown exactly as those sources give them.

Keeping one

4 ft 2 in × 2 ft 1 in × 6 ft 2 in(126 × 63 × 189 cm)

Minimum length × width × height, for one animal. Bigger is always better.

The standard sizes snakes as a fraction of total length: 1 × 0.5 × 1.5.

Recorded both on the ground and climbing, so this is the larger of the two rules in every dimension.

Mindestanforderungen an die Haltung von Reptilien (Sachverständigengutachten), German Federal Ministry for Nutrition, Agriculture and Forestry, Animal Welfare Division, 10 January 1997. The standard states these floor areas are recommendations rather than binding limits.

From this animal’s own total length of 4 ft 2 in (1259 mm), at 1 × 0.5 × 1.5 times it, following the German federal welfare standard — how this is worked out.

No preferred body temperature has been recorded for Spotted Python. Rather than repeat a number from a care sheet, this page leaves it out.

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.

128kJ per day

Worked out for an animal of 1,466 g, the heaviest recorded for Spotted Python — 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.

Morphs

0 with peer-reviewed genetics behind them, 3 resting on breeder consensus. Most references present both with the same confidence.

What each pairing produces → · Two genes at once →

  • Albinobreeder consensus

    No black pigment, leaving tan and cream blotching with red eyes.

  • Blotch size and contrastbreeder consensus

    How large and how strongly edged the blotches are, and how dark the ground. Selected over generations rather than carried by one gene.

  • Granitebreeder consensus

    Blotches broken into fine speckling running the length of the animal.

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.
