Totem warrior animal choices [duplicate]


My question for today is, when a totem warrior barbarian chooses a 2nd animal after his 1st animal at level 3, do they get the first ability presented at level 3? Or do they get the new ability?

For example, lets say i chose the bear at level 3, and then at level 6 i chose the eagle. Will i get the eagle’s ability which was presented at level 3? Or is that option no longer available, and i’ll get the ability the eagle gives at level 6?
