@bertiegregory: Dan Beecham and I were trying to film krill off the coast of Elephant Island in Antarctica. On one particular dive, we jumped in about 300m/1000ft of water and found this Antarctic krill had been caught by a ctenophore. Both Dan and I got total tunnel vision filming this epic but tiny little battle for survival. At that point, I realised behind Dan was a 25m/80ft fin whale! I’ve never screamed that hard into my diving regulator.
