Baby Bitten By Rattlesnake And Lives.

In the morning, on Wednesday, September 12, at a daycare operated by Naval Base San Diego, California in Chollas Heights, a 15-month-old baby boy was bitten by a baby rattlesnake.
His hand swelled up to four times its normal size.

He was rushed to a children's hospital nearby where he was given antivenin. 

The snake bite could have killed the boy because of his age and size.

After taking a few days to recover, the swelling from the bite and the fever have both gone down and he was back to his playful self.

There are more than 24 rattlesnake species.

The rattle noise comes from the sound created when hollow and bony doughnut like segments in the rattle bang together.

Young rattlesnakes have not yet developed this warning mechanism. 

They are still just as venomous as a full-grown rattlesnake, and have fangs that can penetrate the skin to inject their venom. 

They also tend to be more aggressive, making them more likely to bite.
A rattlesnake can strike at 5.9 feet per second.

It is one of the fastest movements by any animal with a back bone.
The rattlesnake’s triangular head contains a hollow spot between the eyes and nostrils.

This is called a pit and is a sensory organ that helps the rattlesnake hunt in darkness by detecting body heat.

Their eyes see well even in low light.

They detect movement by sensing the vibrations in the ground.
