A bunch of cards over there at the BBC.  Here's a quote from the story:

"Aquarist Darren Gook was trawling the internet when he came across news of a yellow lobster caught by fisherman near Whaleback Island, New Hampshire."

Get it?  Trawling?  As in fishing at the bottom of the ocean with a net where you find lobsters…but talking about the internet instead?  Oh, the dry English wit…always right on point…
