Well flamminwoodchuck was first with a common name (actually 2) that have been used for that fish, but you had a Linneas classification that was once valid,

It has been also sold as bagre, begre, bagre tete, bagre shark, grey shark, jordan sea cat, and silver shark, and that was just what I found before getting tired of chasing links.
