European Spiny Lobster

Overview

The European Spiny Lobster (Palinurus elephas) is a large, heavily armored crustacean found in the Mediterranean Sea and the northeastern Atlantic Ocean. Often referred to as the "crawfish" or "langouste rouge," this species is highly valued in fisheries, which has contributed to its status as a vulnerable species in many parts of its range.

Distribution & habitat

This species primarily inhabits rocky, exposed coastal environments within the circalittoral zone. While it can be found from the British Isles south to Mauritania, including the Azores and the Mediterranean, it is most commonly observed in rocky crevices or caves that provide protection from predators.

Appearance

Palinurus elephas is characterized by a stout, reddish-brown carapace covered in sharp, forward-pointing spines, with particularly prominent supra-orbital spines. It possesses two long, heavy, and spiny antennae that are longer than its body. While typically orange-red with yellow spots, individuals may occasionally exhibit brown, sandy, or purple colorations. Unlike some other lobsters, it lacks large, crushing claws, instead featuring small, hook-like appendages.

Biology & behavior

These lobsters are nocturnal, remaining hidden in rock crevices during the day and emerging at night to forage. They are known to be social, often sharing the same hiding spots with others of their kind. Their growth occurs through molting, a process where they shed their old shell to expand in size.

Feeding

As opportunistic feeders, they primarily consume a variety of benthic organisms. Their diet consists largely of sea urchins, starfish, and various mollusks, whose shells they crush with powerful mandibles. They may also feed on algae, worms, and other crustaceans.
