Pretty awsome.

Imagine, from below the silhouette doesn't resemble a seal, or any other familiar sea creature, to the shark... So there's no immediate imulse to attack - unless maybe territory is involved... but Great White's are travelers, so it's unlikely.

He's just lucky it didn't give him a curiosity nip. ;P

Lordie I would be crying. I certainly wouldn't be screaming because loud noises attract larger predators and that shark seems quite interested enough.
