Blue Planet: A Summary

Your viewing options consist of:

A: Small fish moving in unison
B: Large fish eating the small fish very rapidly and very messily.
C: A large whale eating even more of the small fish.
D: Seabirds diving into the water, possibly to eat the small fish, in slow motion
E: Various crustaceans scuttling around, which is apparently the underwater equivalent of the comedy Glaswegian accent
F: Spawning. Lots and lots of spawning. And it makes me feel dirty.
