I've been chased by Mojave Greens
Were they also 10 feet long.??
Mojave Rattlesnakes, sometimes called Mojave Greens, while having a pretty dangerous bite with venom about 10 times more toxic than any other rattle snake in the US, are not necessarily aggressive. They will defend themselves if they feel threatened, and can be highly irritable and unpredictable. Several people around my area claim to have seen one up to 10 feet long, but the average length is between 3 and 4 feet. The largest confirmed Mojave Rattlesnake ever recorded is 48″ long, (Schuett, Feldner, Smith, Reiserer,
Rattlesnakes of Arizona, pg 568). An Indian friend tells me a story told to him by his grandmother of how his grandfather was chased by a 15 foot Mojave green, and when he jumped into his truck, the snake bit through the tire, then circled the truck looking for a way to get inside. Seems in this area, the more alcohol one partakes in, the bigger the snake becomes.
Other snakes that have a green marking are commonly mistaken for Mojave greens. Mojave Rattlesnakes can certainly be green, and even the brown ones look kind of green compared to the dull grey of their Western Diamondback counterparts. But it is just a color of some Mojave Rattlesnakes, not a separate species. This can lead to confusion, where people misidentify any rattlesnake they see with a green coloration as a Mojave. A good example are the Blacktailed Rattlesnakes, found in mountains and regions where Mojaves either do not range, or do not use. Another are the reports of Mojave green rattlesnakes being found in parts of Eastern New Mexico where they do not live. One was reported in eastern New Mexico last summer but as far as I know it has not been verified.
Not green.
Another misidentified snake is the Southwestern Speckled Rattlesnake. Who appear red or pink in much of their range, yet people still call them Mojave red rattlesnakes, a species which does not exist.
Not a Mojave Red rattlesnake.
This is defensive behavior, not aggression. (still scares my wife, even in a picture)
I have no doubt you saw Mojave Rattlesnakes, but how far was the chase.??
I am by no means a snake expert. I got interested in snakes at age 13 when I was bit on the ankle by a snake. I had watched all the old westerns, so I was convinced I was going to die. Only thing was, it was discovered I was bit by a hognose snake, which is non-poisonous. That is when I learned some snakes are poisonous and some aren't.
When I moved to NM, I was interested in seeing some Western Diamondbacks. A friend took me out to search for snakes, and suddenly he jumped back, ''Look out, that's a Mojave green, the most dangerous rattler there is..." I had never heard of a Mojave green, so I studied up on snakes of the southwest. Now that I have learned a little, I am not convinced what we saw that day was a Mojave Rattlesnake.
The above pictures are not mine. I usually hunt rattlesnakes by myself and I need to keep my situational awareness up, so I don't want to focus on one snake because where there is one, there may be more. I do carry security, because there may be an alien spaceship, or a mountain lion or even bigfoot stalking me....
My wife is from the Philippines, where 99 44/100% of the indigenous snakes are venomous, is a kill them all person. She does not like to watch me catch a snake, look at it, then let it go.
