Shifting out of neutral

So, after a great deal of on-and-off attempts at blogging, a new job, and plans for additional schooling, I have decided I should really get my butt back into gear and post some more. So without further ado, allow me to present a personal favorite: DILOPHOSAURUS!

Dilophosaurus CR 4

With a trilling hoot, the creature hops from the brush. Two short, parallel crests adorn its head, and its whiplike tail waves behind it.

Description:
Growing nearly 20 ft. long, and weighing anywhere from 800-1000 lbs, dilophosaurs prey primarily on smaller creatures, though should medium prey like deer or humanoids look like easy prey, they will not pass on such an opportunity.
The crests are primarily used as identification, with no two dilophosaurs looking exactly alike. 

Tactics:

Dilophosaurus prefer striking and withdrawing, allowing its paralyzing venom to take hold. If escape is impossible, or if faced with an abundance of prey, they will move on to fresh targets as the first victims begin to slow.
