Footage filmed from Bognor Regis beach at the weekend has sparked speculation.
Posting on his Facebook page, Alistair McLean states his belief it was a ‘big shark’.
He wrote: “It came up and fed and then disappeared again only to resurface and feed again. I’m guessing its a basking shark – 17 to 20 foot long.
“It was A few hundred metres West of the boat pound ‘West End’ a couple we passed who live on the beach had a much better picture and said it’s been there a few days feeding.”
However other people have been less certain, with comments ranging from it being a seal to a lobster pot.
