There was a bit on Africa last night where sardines were swimming away from predators and suddenly came to a wall of water that they don't cross so becoming an easy meal for predators.

The birds diving in looked like shells or missiles raining down!

The agility of pretty much everything bar the whale was amazing.

Seeing things like that scares me.

Dunno why.

I dunno, for something that big I thought it was doing a good job but I had to laugh that on every pass it got virtually nothing and eventually realised the effort/payoff ratio wasn't worth it
