Films: Razortooth (2007)
Location: River/Civilized Area/Forest
Height/Weight: Twice that of an average human.
Summary: Eels are not snakes. The ocean already has those, anyway. They are like any other fish, except almost all of them would like to bite your hand and like to live in seclusion. And some just really, REALLY love the taste of meat, even if it's a little far from the water...
History: The mutated result of a scientist's research, this monster eel known as the Razortooth escaped into the part of the Everglades that prisoners often use as a route of escape. Now, the madman's students have been sent to find it so that it may be captured again. But as the bodies mount, they realize that this eel is one Hell of a problem that must be dealt with now.
Notable Kills: Tears through someone in a portable outhouse. Just when we thought those things weren't evil enough...
Final Fate: After killing many, the Razortooth is blown up when it accidentally eats a grenade. However, as the survivors leave, it is revealed that the beast had kids...at least four of them...
Weakness: Anything conventional.
Scariness Factor: 3.5-The CGI is a joke, but the look certainly isn't. Looking less like an eel and more like an oversized viperfish, the Razortooth is pretty much the very worst of serpentine swimmers. Besides, if it can't get you in the water, it'll just follow you to land with that toothy frown to bear down on you...
Trivia: -The largest eel in the world is the European conger, which can grow up to six meters long. They are also known for sharing the holes they inhabit with morays.
-The Razortooth's harm to the Floridan countryside is partially based off of the invasive nature of the Asian swamp eel. One of Asia's most common fish, it was first introduced to Hawaii in the 14th century before thousands of them were introduced to the southern U.S. riverways around 1990. From that moment on, they've been a predatory blight on the ecosystem due to their resilient nature and huge population.
