Good for tanking all turrets except tek turrets, do whistle attack target or ride it and have a tribe mate feed it veggie cake. I once drained the alphas tribe (they weren't that good tho) turrets and raided them with my tribemates. (But 5 in game days later "You were killed by ducky! (Parasaur) lvl 34!"
First dino I ever tamed and bred. In my opinion its a slow breeder. But hell of a defender. Its just a good tame all around especially due to the fact its 10x better then a trike (in defense) and the saddle is relatively easy to unlock. Plus its got a cool swimming animation.
