Anaconda (feeding)
Color of Life Note: The dark brownish-green Anaconda demonstrates concealment by laying hidden in the murky waters of the Amazon. It is is more visible at the California Academy of Sciences exhibit water which is markedly more transparent.
TAXONOMY
Kingdom: Animalia
Phylum: Chordata
Class: Reptilia
Order: Squamata (scaled reptiles, all lizards and snakes)
Family: Boida (Boas)
Genus/species: Eunectes murinus
GENERAL CHARACTERISTICS Can grow to more than 29 feet (8.8 meters), weigh more than 550 pounds (227 kilograms), and measure more than 12 inches (30 centimeters) in diameter. Gigantic, heavy-bodied, dark green boa with dark spots. A distinctive stripe runs from the rear edge of the eye, diagonally downwards to the back of the head. The stripe is edged with black and varies in colouration, from greenish to orange. Eyes and nasal openings are on top of their heads, allowing them to lay in wait for prey while remaining nearly completely submerged. The female dwarfs the male and is almost five times heavier.
DISTRIBUTION/HABITAT South America: Amazon and Orinoco drainages from Colombia and Venezuela to East Bolivia and Central Brazil. Associated strongly with watercourses, swamps and other freshwater locations.
DIET IN THE WILD Monkeys, deer, peccaries, pacas, agoutis, birds, fish, caiman and turtles. Prey usually killed by constriction; prey suffocates but is not crushed. Usually feed in water. Jaws attached by stretchy ligaments allow them to swallow their prey whole, no matter the size, and they can go weeks or months without food after a big meal. Primarily a lie-in-wait predator.
Academy Diet: Frozen/thawed rabbits (P. Dwight Biologist).
REPRODUCTION Female anacondas retain their eggs and give birth to two to three dozen live young. Baby snakes are about 2 feet (0.6 meters). After mating, the female may eat one or more of her mating partners, as she does not take in food for up to seven months.
MORTALITY/LONGEVITY: Lives to over 29 years.
CONSERVATION: Not threatened.
REMARKS: The anaconda is, pound for pound, the largest snake in the world. Its cousin, the reticulated python, can reach slightly greater lengths, but the enormous girth of the anaconda makes it almost twice as heavy. Can remained submerged for a very long time lying in wait for its next meal.
Academy specimen is a female. She is now (2013) 13 ft 11 inches long and weighs 92 lbs. In 2008 she was 3m (10 feet) long and weighs 90 lbs.
