This is an awful animal to underestimate. When I first played the game, I thought I could kill one for easy meat and resources. The douche took 6 spears to the face, broke my leg, and speed-walked after me as I limped away. DO NOT UNDERESTIMATE.
If you are a low level, and u hit one with others near by, you can easily run, but be warned-when you are level seventy three, you will see a whole army of 1,000 from that one time you hit that one turtle. You can run, but u cannot hide. You could go to Neptune, but they will find you. The only way is to kill or tame them all, or they will never stop chasing you
