This is a very cool practice among this species, digging with their young on their back is a pretty cool way to show their offspring how to dig, and It might not be intentional, (don't quote me on that) I still think it's pretty cool to see a sight like this, since a lot of these giant anteaters are being killed off every day, and they are some amazing animals. And come on, baby anteaters!
Personally I think the fact that they carry their young on their back is fascinating and amusing. Logic would dictate they would just walk along with the mother as most (all) fully terrestrial placental mammals do.
@ThylacineAlive Yeah! I do think the fact that the mothers carry the babies on their back is pretty awesome, and surely provides some thoughts about, "what would it be like to be a baby anteater riding on another anteaters back"? .
