PC/Console:

Use these only for their speed (traveling, taming or speed-running an underwater cave) as they are really squishy.

Even with 45 points in HP and imprinted, these come out a little over 1000HP. Leveling health gives like 10HP per point. Just put all levels in speed and use other ocean dino's for battle.

On PC/console just like every tamed creature, everything aggro's so just use your speed to outrun them. It's only on mobile that nothing aggro's on them.
