These things are used for one thing and one thing only: speed. Invest it all in speed and nothing can hope to match you underwater. A good Dino to kite with

If you use it to get oil and silica pearls, set to passive, it won't swim away when attacked

If you are struggling with getting silica pearls and dont have scuba gear, these are great for finding them underwater on the center. Just look in the rivers and you'll have plenty after!

Very good for gathering resources such as slica pearls and oil. They can also be used as a getaway Dino if u are raiding
