Ulliott (1 April 1954 – 6 April 2015), known by the nickname Devilfish, was an English professional gambler and poker player.
Formerly, Ulliott was a minor figure in the Hull underworld, but went on to become a World Series of Poker bracelet-winner, and a mainstay of televised poker.
At the poker table, he was known for wearing orange-tinted prescription sunglasses, a sharp suit (or leather jacket) and gold knuckleduster rings reading "Devil" and "Fish", which he made himself.
