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.
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:
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.
