Concerning Belugas: Forward Rolls?

What are you doing Nemo?

Nemo's behavior can only be described as... gymnastics??? I will most certainly look into the behavior of wild Belugas- and see if they ever exhibit such odd behavior. Nemo is literally attempting a sideways roll. I'm wondering if this is playful behavior for Belugas.

 Rolling...

 Almost made it

Wake seems to be utterly unperturbed by Nemo's rolling. Who is now righting himself.

Rolling is complete: time to continue playing.

Nemo continues to surprise me. I will try to look into this odd behavior as soon as possible.
