Care Sheet

Green Anaconda (Eunectes murinus)

Common names: Green Anaconda

Size: 3.6-4.8m is average. However, exceptionally large specimens can exceed 6.6m (22ft).

Age: 15-20 years is average. However, this species have been known to live 30 or more years.

Difficulty: High. Due to the size of Anacondas, they should only be kept by experienced keepers. Most captive bred Anacondas have steady temperaments (unlike wild caught specimens). However they will still have a strong feeding response which makes them potentially very dangerous.

Temperature: 78-82°F.

Humidity: High. The enclosure should be sprayed daily to maintain humidity. Water needs to be changed everyday.

Housing: 240x90x60 (8ft) is adequate for an "average" adult Anaconda. This species is incredibly strong so any enclosure designed for keeping Anacondas should be very strong. Small plastic enclosures such as breeder boxes and small faunariums are suitable for hatchling and juvenile Anacondas.

Heating: Dependent on what enclosures you are heating. Plastic enclosures can be heated using heat mats, whereas wooden vivariums or similar housing should be space heated using bulbs, ceramic heaters or heat plates.

The three most important things to remember when heating any enclosure are:

  • Ensure the animal cannot burn itself with the correct fitting of the heat source and protecting it with a guard.
  • Choose the appropriate wattage for the size enclosure. This can help further reduce the risk burns and overheating (it can also help save energy!)
  • Always using an appropriate thermostat. (Refer to Thermostat Guide)

Substrate: Orchid bark is a widely used medium for keeping Anacondas on. Unprinted newspaper is perfect as hygienic flooring, although it does need to be changed quite regularly.

Diet: Defrosted rats. Adult Anacondas will eat very large rabbits.

Natural Distribution: South America.

Things to note: Anacondas are the largest snakes in the world. The current world record is just over 5.2m (17ft) and weighing almost 100kg.
