Faster swimmer than my 140.5% Movement Speed character with flippers, with base speed it can outswim pretty much any wild ocean creature.
Can be used to lure Mantas into taming pens at pretty early levels, and is much more maneuverable than any other amphibious mount. When ridden, can also side-strafe and VERY slowly swimm backwards if you so wish.
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.
