Awesome for someone who hasn't pumped oxygen and wants to hit deep sea loot crates and get pearls. Tamed a 145 with prime and pumped speed and stam. Was my favorite underwater tame hands down. You still want to bring flippers though.
Can ride but only underwater. In order to ride, hold whatever your ride button is and click the option that says ride. Level up in oxygen, health, and movement speed if using this for underwater dives. Really fast underwater, and can outspeed megalodons.
