MUD DEMON (RIDDICK)
A Planet which is "not Furya"
Mud demons are the predatory creatures found on the planet known only as “Not-Furya”. Riddick encounters them early on in the film Riddick.
The mud demons live on the scorched planet and lie dormant within the ground until the rain season begins. When the rain season begins, the mud demons emerge from the ground, ready to kill since they need to have their skin wet at all times. The mud demons have developed breathing holes in their tails, to remain submerged even longer. They come in a variety sizes, bearing razor sharp teeth, two legs, and a scorpion like tail. Their bite is paralyzing and venomous depending on their size. The mud demons are like rattlesnakes. The babies are more dangerous than the adults because they can’t control the amount of venom injected into their prey. The mud demons also trick their prey during dry seasons by raising their tails out of the water to hypnotise the prey into believeing the tail is the creature and attack.
