I'm around lvl 30 and ever since I started the game I can honestly say "I hate these creatures!" I've died by them more then anything else lost two parasaurs, a raptor, and who knows what else. Advise keep glancing under water to see if any are around, avoide rivers crossing on foot. I like rock hopping and dino swimming they can take more damage
These piranhas are SOOOO annoying!One time I was passive taming and Equus and it ran into the water, Then about 2-4 piranhas came up and killed my Equus! I was so sad and I went and killed them. WildCard, If you see this lower the percentage of piranhas. Thank You!
