Tips & Strategies

Level oxygen, movement speed and health, tame a higher level so you don't have to pump most of your levels into health, at first it may look like you can't ride it because it doesn't have the option or of the water, but once you get in the water, you can suck oxygen out of it so if your playing on primitive plus or don't have scuba yet it's very good

These guys are the kings of trilobite hunting. Not only do they deal additional damage to them, they're great at collecting chitin, oil, and pearls. Other perks: they don't need a saddle to be ridden while in the water, they provide you with oxygen underwater, and are faster than just about anything while swimming. Super underrated mounts imo.
Please listen to me! I haven't had these guys for long, but I noticed their healing was very low, about 0.1, while on land. When I went into the water with it so it could swim, the healing went up to about 1.2 per second. But the biggest thing is, I force fed it meat to heal, like with all carnivores. If you do this in the water, it heals hundreds with just a few pieces! I am going out to the seas in a bit. Knowing this healing factor will help a lot!
