Norway Lobster

Overview

The Norway lobster, also known as the langoustine or scampi, is a slender, pale orange crustacean widely recognized as a significant commercial species in Europe. It is the only living member of its genus and is typically found in deep, low-light marine environments where it leads a cryptic, burrow-dwelling lifestyle.

Distribution & habitat

This species is distributed throughout the northeastern Atlantic Ocean, ranging from Iceland and Norway down to Morocco, and is also found in the Mediterranean and Adriatic Seas. It is notably absent from the Baltic and Black Seas. These lobsters are strictly associated with soft, cohesive muddy sediments that are stable enough to support their unlined, shallow burrows.

Appearance

Resembling a smaller, more delicate version of the common lobster, the Norway lobster typically reaches 18–20 cm in length, with a maximum of 25 cm. Its body consists of a fused cephalothorax covered by a carapace and a long, segmented abdomen ending in a broad tail fan. Key features include large, black, movable eyes, two pairs of antennae, and three pairs of clawed legs. The first pair of legs is notably elongated and features distinctive, spiny ridges.

Biology & behavior

Norway lobsters are primarily nocturnal, often emerging from their burrows at night to forage. They exhibit complex social behaviors, including the establishment of dominance hierarchies, and rely on a combination of vision, chemoreception, and mechanoreception to navigate their environment.

Feeding

As opportunistic predators, they feed on a variety of prey, including worms, molluscs, echinoderms, and other small crustaceans. They often time their foraging activity to coincide with dawn and dusk.
