It supposedly hides in muddy, abandoned alligator caves, thus the smell.

More than 75 sightings were reported in Florida in the past two decades. The scare had started when an amateur archaeologist claimed he'd seen the thing in southwest Florida's Big Cypress Swamp.But it was concentrated locally in the 1970s, when South Florida then had more open space and about half the people it does now. A local dispatcher said he was advising lawmen that locals were so jumpy the cops should identify themselves when they approached homes."I know it exists," Palm Beach County Sheriff's deputy Marvin Lewis said in 1980.He said he and fellow deputy Ernie Milner made some 50 forays to the wild. They said they shot something in 1974 west of Lantana that grunted and fled back to the dark. Another time, they found mysterious hair on a barbed-wire fence.

Several reports of a creature with a sail-like body and a flipper on the end of its nose exist in this region of water off the Shetland Isles. A fishing crew who encountered it stated the beast destroyed several of their nets, and came so close to their boat they could detect a pungent stench.

But if smell is an indication a cryptid may be near, it is a good tracking device and should perhaps be one that should be taken more seriously. Next time you smell something awful, when out in a boat , or in the countryside, investigate it, it could be something cryptozoological is passing that way.
