If
you look in the records there is a lot of controversy over which snake holds
the world's record for massive size. The dimensions that have earned the
anaconda the title of king is its total body mass or its weight (the sheer
physical bulk of it). The largest anaconda ever measured was almost 28
feet long with a girth of 44 inches. She wasn't weighed at the time she was
caught, but scientists estimate that she must haveweighed over 500 lbs. The
other snake that competes with the anaconda is the Asiatic Reticulated Python (Python
reticulatus). The python holds the world's record for length of a snake,
with the longest ever measured at 33 feet. Even though the longest python
is longer than the record-holding anaconda, the girth of the anaconda is far bigger.
Anacondas in the jungles of South America can grow as big around as a grown
man!
The Secret Life of an
Anaconda
Anacondas
in the wild spend most of their time
hanging out in rivers hunting for their food. They are solitary creatures that
are somewhat shy and not many of them are easily seen. They are very well
camouflaged in the swamps and bogs in which they thrive. There are some
historical reports of early European explorers of the South American jungles
seeing giant anacondas up to 100 feet long and some of the native peoples of
the South American jungle have reported seeing anacondas up to 50 feet long. No
one has caught and measured an anaconda anywhere near that size. It is
important to note that when a dead anaconda's hide or skin is laid out it can
be stretched very easily, expanding to much longer lengths than the snake
exhibited when alive. Reports of outsize anacondas that cannot be verified
are usually due to distortions in perception, or a snake skin being
disproportionately stretched and inaccurately measured. People are generally
really bad at estimating length, especially for larger snakes. In fact, the
larger the snake, the larger the margin of error.
Anacondas
like to hang out in rivers so it would be difficult to estimate the length of
one seen swimming without seeing the entire snake. It's the anaconda's ability
to remain partly hidden in the water that makes it difficult to accurately find
(and document) a specimen that exceeds the current world's record. (Would you want
to jump in the water after a giant anaconda to try and measure a snake big
enough to kill you?)
The
Biggest Snake to Have Ever Lived
If you think that an anaconda big enough to swallow a
capybara or tapir whole is big, you should see the size of the giant snake
scientists discovered in a coal mine in Columbia, South America in 2008.
Fossils of an enormous snake were discovered in an open coal mine in the Amazon
rainforest. Paleontologists
estimated the length of the snake - called Titanoboa - to be 43 feet long and
estimated to weigh 2,500 pounds! Based
on their findings, the scientists who identified this new species of snake said
it was large enough to prey on crocodiles. Since snakes are cold-blooded, the
average temperature of the Amazon had to have been 6 to 8 degrees warmer to
support a snake that enormous.
Killer Snake
Anacondas are members of the boa constrictor family of
snakes. That means that they kill their prey by coiling their large, powerful
bodies around their victims and squeezing until their prey suffocates or is
crushed to death and dies from internal bleeding. Then the snake unhinges its
jaw and swallows the victim whole. Anacondas are much more likely to eat
aquatic creatures, such as fish. Occasionally, they have been known to eat:
caimans (a relative of the alligator), other snakes, deer, and even jaguars.
Anacondas are rather slow-moving snakes, so they have to rely on stealth and
the element of surprise to catch their unsuspecting prey.
Do Anacondas Bite?
Just about every species of snake on earth has teeth, but
the anacondas' teeth are not used for chewing. Snakes' teeth are used for
holding onto their prey, preventing them from escaping. Some snakes have venom
in two specially designed, extra long teeth (called fangs) which they use to
kill their prey. Anacondas have teeth, but they are not a venomous snake. They
rely on their enormous size and power to subdue their victims. It is possible
to be bitten by an anaconda, but the bite itself would not be fatal.
