  • Terrestrial
  • Humidity
  • Iridescence

At a glance

ADULT SIZE1,2–1,8 m
Smithsonian range. [2]
LIFESPANUp to 20 years
Maximum cited in captivity. [2]
LIFESTYLEMostly on the ground
Branches are also used. [1][2]

Adult size

Around 1,2–1,8 m according to the Smithsonian. [2]

Adult weight

No adult range by sex and length is sufficiently documented in the selected sources. Do not use the masses of another Epicrates as a target.

Lifespan

Up to 20 years in captivity according to the Smithsonian; this is not an average. [2]

Lifestyle

Mostly terrestrial, with use of branches. [1][2]

Experienced keeper

The balance between humidity, ventilation and temperature, particularly in juveniles, requires regular readings and a proven enclosure. Editorial assessment. [3][5]

Housing

SHELTERS AND BRANCHES

≈ 180 × 90 × 90 cm — ReptiFiles adult reference; adapt to body size. [3]

ReptiFiles suggests around 180 × 90 × 90 cm for an adult, with shelters and strong supports. [3]

Care parameters

WARM SURFACE · DAY

30–32 °C — Local heating according to ReptiFiles [3].

AMBIENT AIR · DAY

≈ 26–29 °C — Conversion of 78–84 °F; night at 22–24 °C [3].

Humidity

70–90 % — Reference from the veterinary table devoted to Epicrates cenchria [4].

Warm resting surface

30–32 °C. [3] Local ReptiFiles reference, to be distinguished from ambient air.

Daytime ambient air

Around 26–29 °C. [3] Correct conversion of the published 78–84 °F; the printed °C conversion is inconsistent.

Humidity

70–90 %. [4] Range from the veterinary table, not permanent substrate saturation.

Night

22–24 °C. [3] ReptiFiles night-time reference.

Feeding

AN APPROPRIATE DIET

Thawed rodents; juveniles every 7–10 days, adults every 14–21 days in the clinical care sheet. References to be individualised. [5]

Identity and complete habitat

Epicrates cenchria is separated from Epicrates maurus in the current taxonomic database. Older care sheets that extend its distribution into Central America sometimes combine distinct species. [1]

The Smithsonian describes it in humid Amazonian habitats, on the ground but also on branches. Its reflections come from the microstructure of the scales and vary with lighting. [2] Provide strong supports and shelters; the ReptiFiles enclosure volume is an adult reference, to be enlarged according to actual length. [3]

Heat, humidity and lighting

The cover temperatures follow ReptiFiles. Its printed conversion for ambient air is inconsistent: 78–84 °F corresponds to around 26–29 °C, not 29–30 °C. [3]

The archived veterinary table gives 70–90 % humidity. [4] ReptiFiles makes more distinctions between day, night and young animals; these frameworks are not averaged. The clinic suggests 70–80 % and low-level UVB without a UVI target. [5] Have a coherent protocol clarified for the life stage concerned.

Substrate and water

ReptiFiles describes moisture-retaining ground, a humid hide and a container that allows bathing. Remove soiling and keep ventilation functional. [3]

Record humidity at a known time and note spraying. The presence of a container indicates neither that the water is clean nor that the air is humid enough; these are two elements to check separately in the log.

Contextualised feeding

The Smithsonian feeds its boas rats. [2] Chicago Exotics suggests whole thawed prey, every 7–10 days for juveniles and every 14–21 days for adults. This clinical rhythm must be contextualised according to body size and condition. [5]

Not all the advice on this older page is reproduced: its introduction uses overly broad taxonomy and distribution. [1][5] Monitoring accepted meals and weight allows an individual plan to be discussed, without inventing a universal percentage.

Reproduction: birth of young

The Smithsonian describes live-bearing reproduction with a gestation of around five months and independent newborns. [2] There are no laid eggs to place in an incubator as there are with a python.

Preparation must focus on the female’s condition, identification of the parents and accommodation for the young. No seasonal reduction or breeding-mass target is prescribed in this profile; ordinary husbandry parameters are not enough to manage reproduction.

Health and daily observation

The clinic highlights sensitivity to excessive temperatures and the need for suitable humidity. [5] Abnormal breathing, regurgitation, retained shed or a marked change in general condition must be reported to the veterinarian.

Record air and surface temperature separately, humidity, mass, meals and sheds. Photographing the enclosure after any major change helps explain the readings. Documentary limits are deliberately retained: they show what still needs clarification for this animal.

Checklist

  • Check closures and supports.
  • Identify every measurement zone.
  • Keep provenance data.

Observations to record

  • Meals
  • Weight
  • Sheds
  • Temperatures

The app provides individual animal records. Check which features are available for your animal in the released version.
