MY REPLACEMENT !!????

 Hello Everypiggy,I have found some very interesting news.There is a new animal.

  He is commonly found in           Louisiana,and he lives in a 
  swamp. 
  He is GREEN,SCALY,CARNIVOROUS,
  and has LOTS and LOTS of TEETH.

  If you think you know what my
 POSSIBLE REPLACEMENT is, then 
 please let me know by leaving a
 comment.
         PIGGY OUT :)!

 (Bonus:When he jumps out of water   he CAN jump 2/3 his size)
          [two thirds]

   Wait,WILL HE EAT ME ???
