The tuskaphant descended from the gigaphant. It has replaced the gigaphant in the Hydro-Nuke Savanna. The tuskaphant's legs became shorter, and the trunks grew a bit longer so it can eat the violetgrass. It has also developed "thumbs" on the trunks, like Earth's African elephant, so it could hold onto the food. They now live in herds of at least 15 individuals.
One noticeable difference from the gigaphant is that the tuskaphant, as its name suggests, has very long tusks. The males have long tusks while the females' are much shorter. The tusks are used to fight for mating rights.
