Grab, Squeeze, and Swallow: How the Anaconda Gets a Meal

Prowling along a side stream flowing into the Amazon River, the fifteen-foot-long green anaconda is nearly invisible. Only her eyes and nostrils stick out above the muddy water. A small pig from a jungle village wanders toward the edge of the stream for a drink, completely unaware that the anaconda has stopped in the shallows near the bank. She is watching the pig getting closer and closer.

As the pig starts to lap up water, the snake submerges and approaches from beneath. Her mouth is full of sharp teeth which curve backwards. Once she locks onto her prey, there is no way for the animal to pull free. Struggling just sets the teeth deeper and makes the snake's grip more secure.

And then the anaconda GRABS. The pig's squeal is short, just one more eerie noise among the other jungle squawks and screams.

Swiftly the snake wraps a couple of coils around the pig's body and SQUEEZES. Almost instantly the pig is unable to breathe. The pig's eyes are terror-filled; the anaconda's eyes are emotionless. After a couple of minutes, the anaconda releases the pressure, unwraps her coils, and prepares to dine.

However, there are no fancy table manners here! Madame Anaconda drags the pig into some undergrowth on the bank, dislocates her jaws, and begins to SWALLOW the still-warm body of the pig head first. After half an hour only the pig's hind legs are still sticking out of the anaconda's mouth, but soon the pig completely disappears. Only a pig-sized bulge in the anaconda's body shows what has happened. It will be several days before the snake completely digests the pig and returns to her slim former self.

The villagers have lost a pig, but the anaconda has had a meal that will last her for weeks or months.
