Scott sent me a message about snakes so I thought I would post a photo of a Western Diamondback Rattlesnake I came across the other day. He* looks pretty serious, constantly keeping an eye on me as I lay on the ground taking his photo.
Some notes about rattlesnakes:
- The Latin name Crotalus atroc means rattle (or little bell) and savage.
- You cannot determine the age by the number or rattles, a new segment is added each time they shed which can happen 1 - 4 times a year. The segments also break off.
- They don't have eggs like some snakes, instead they have 4 - 25 live young.
- The tongue is used to smell instead of taste.
- They have heat sensing pits on the front of their head that helps them locate warm blooded prey, that's why they are called pit-vipers.
- The venom is more potent in juveniles but they don't inject as much as adults.
- The venom is hemotoxic which damages tissue and affects the circulatory system by destroying blood cells, skin tissues and causing internal hemorrhaging. The venom may also contain neurotoxins which affects the nervous system and breathing.
- Around 25% of bites to humans do not contain any venom, the snake is biting out of self-defensive and saves the venom for their prey. The bad thing is the other 75% of the time.
- Approximately 8,000 people a year are bitten by poisonous snakes in the United States and 9 - 15 victims die.
Here are some photos of a juvenile I came across last year (click thumbnails to see larger photo).

* It might be a female, I'm not sure.
