Irish langoustines (Nephrops norvegicus), are part of a family of large marine crustaceans called Nephropidaeare. In fact, they are the smaller cousins of the European (Homarus gammarus) and American lobster (Homarus americanus).


Why Dublin Bay Prawn?

Irish langoustines are commonly referred to as Dublin Bay prawns in Ireland and the UK. It has been suggested that the term stems from the Irish national postal service. The crew from the postal vessel travelling from Holyhead to Dublin in the early 20th century used to moor off the Dublin coast awaiting permission to dock. Whilst waiting they used to cast a net and would haul up a catch of Irish langoustines. Given that it was Dublin Bay, the little creatures acquired the term Dublin Bay prawn.

Another suggestion is that when fishing boats from the North Sea were sheltering from poor weather they sold their catch in Dublin Bay before moving on again. A final suggestion is that fishing boats coming into Dublin Bay sold their catch to street vendors, which included 'Dublin Bay prawns'.
