What is "nephrops norvegicus"

Lobster \Lob"ster\, n. [AS. loppestre, lopystre prob., corrupted fr. L. locusta a marine shellfish, a kind of lobster, a locust. Cf. Locust.] (Zo["o]l.)

1. Any large macrurous crustacean used as food, esp. those of the genus Homarus; as the American lobster ( Homarus Americanus), and the European lobster ( Homarus vulgaris). The Norwegian lobster ( Nephrops Norvegicus) is similar in form. All these have a pair of large unequal claws. The spiny lobsters of more southern waters, belonging to Palinurus, Panulirus, and allied genera, have no large claws. The fresh-water crayfishes are sometimes called lobsters.

2. As a term of opprobrium or contempt: A gullible, awkward, bungling, or undesirable person. [Slang]

   Lobster caterpillar (Zo["o]l.), the caterpillar of a European bombycid moth ( Stauropus fagi); -- so called from its form.

   Lobster louse (Zo["o]l.), a copepod crustacean ( Nicotho["e] astaci) parasitic on the gills of the European lobster.

Nephrops norvegicus, known variously as the Norway lobster, Dublin Bay prawn, (compare langostino) or scampi, is a slim, orange-pink lobster which grows up to long, and is "the most important commercial crustacean in Europe". It is now the only extant species in the genus Nephrops, after several other species were moved to the closely related genus Metanephrops. It lives in the north-eastern Atlantic Ocean, and parts of the Mediterranean Sea, but is absent from the Baltic Sea and Black Sea. Adults emerge from their burrows at night to feed on worms and fish.
