"Getting accidentally rolled and pinned against a boat today by an overly amorous whale shark mic-drops that."
Clarke, who hosts TV programme Fish of the Day, is an avid fisherman and has no shortage of fishing adventures.
Several years ago the 39-year-old nearly died in Niue while freediving.
He had speared a larger-than-expected dogtooth tuna, which dragged him further into the depths of the Pacific.
After a few minutes underwater, 30m down and running out of breath, he desperately swam to the surface, but blacked out mere metres away.
Fortunately, his friends were there to haul him out of the water just as he was coming to.
