One hiker in Florida, Tracey Cauthen, discovered a rare rainbow-colored snake, a rare species that experts haven’t seen in that area for over 50 years.
Cauthen spotted the beautiful four-foot-long snake while hiking through the Ocala National Forest, which is 47 miles north of Orlando. The Florida Museum of National History confirmed this sighting was the first one recorded in Marion County since 1969.
Fortunately, this snake is completely harmless and nonvenomous. Its average adult size is around 3 feet 6 inches, although the longest has been recorded to be 5 feet 6 inches by the Florida Museum of Natural History. They are usually found near bodies of water, hiding amongst the vegetation. 
“Rainbow snakes are highly-aquatic, spending most of their life hidden amongst aquatic vegetation; seldom seen, even by herpetologists, due to their cryptic habits,” said the Institute on Fox 8 News. “Burrowing near creeks, lakes, marshes, and tidal mudflats, rainbow snakes specialize in eating eels, earning the nickname ‘eel moccasin’.” 
How to Tell if a Snake is Venomous?
First off, it’s important to note that there is are very few ‘poisonous’ snakes, not because they aren’t dangerous, but because the word poisonous is a misnomer in this case. Poisonous indicates a substance that is toxic when ingested (i.e. if you ate the snake you’d become ill or even die). Venomous, on the other hand, is when an animal injects toxins into the body of their prey via biting or stinging. Since we generally don’t make a habit of eating snakes, the venomous variety are the one’s hikers, gardeners, and the like, need to watch out for.
You may have seen or heard of many ways to spot a venomous snake, such as checking for round or slit pupils or the shape of their snout. However, there are so many exceptions, that these rules become impractical. In fact, many of these ‘rules’ are just plain wrong.
