Our guide warned us of dangerous insects, reptiles and plants. One of the deadliest snakes in North America is the Mojave Green rattlesnake. You don't want to be bitten by a Green.
When I saw my friend quietly nursing her wound, I became concerned. Symptoms from snake bite are sometimes slow to show up, causing victims to underestimate the severity of the encounter. First, you feel weakness in your muscles then you experience shortness of breath and extreme pain. Antivenin is necessary for survival.
Of course, I--being trained and certified as an Emergency First Responder (EFR)--had to get a photo of the wound first! I have my priorities your know....
Thank God my friend explained that it was not a snake that bit her, but a yucca. Even a plant can bite you!
