Nephrops norvegicus is a small lobster, pale orange in colour. It grows to a maximum total length of 25 cm (including the tail and clawed legs), although individuals are normally between 18-20 cm. The head and thorax have a non-segmented cover (the carapace) while the long abdomen is clearly segmented with a broad fan-like tail. The first 3 pairs of legs bear claws. The first pair of legs are very elongated with longitudinal, spiny ridges. There are 2 pairs of antennae, the second pair much longer and thinner than the first. The eyes are large, black, and moveable.Also known as the Dublin Bay prawn, scampi and langoustine.
