Be aware if you try to breed one of these, they occasionally won't eat the food in their inventory and need to be force fed. I have seen this in the juvy/adolescent stage as well so don't assume they will eat from the trough.
If you intend to breed this beast, I will give one tip to save you a headache, the babies will often have such low food they will starve with raw meat in there inventory, so I advise you to use cooked fish meat till they eat raw fish, then cooked meat till they can eat raw.
Range is the best way to kill these poisonous
dinosaurs. The time you would want to get close to these monsters if you have a lot of weak tames like dilos or a powerful tame like a carno. Unless you want to tame it then good luck to you and say bye to some of your dinosaurs.
