Identification & Biology

IdentificationA large lobster with a cylindrical, spiny carapace and very long, thick antennae. Unlike true lobsters, it has no large front claws. The body is reddish-brown to purple with yellow and white markings. The abdomen segments are banded.
SizeBody length up to 50 cm. Weight up to 8 kg. The antennae can be longer than the body.
Social HabitCan be solitary but often found sharing crevices with other individuals. Nocturnal, hiding deep in caves and holes during the day. Makes a loud rasping sound by rubbing the base of its antennae against the shell as a predator deterrent.
HabitatRocky reefs, caves, crevices, and boulder fields. Requires hard substrate with deep, dark shelter.
Depth5 to 200 m. Most common between 10 and 70 m.
Feeds OnMussels, sea urchins, barnacles, worms, and other invertebrates. Forages at night across the reef.
DistributionEastern Atlantic from southern Norway to Morocco, and throughout the Mediterranean Sea. Present in Maltese waters but heavily fished.
DescriptionPalinurus elephas is one of the most commercially valuable crustaceans in the Mediterranean and has been heavily exploited for centuries. In Malta, divers occasionally spot individuals deep inside caves and crevices, usually betrayed by the tips of their antennae protruding from the darkness. The species is listed as Vulnerable by the IUCN in the Mediterranean due to sustained fishing pressure.

Detail

Preferred Environment

Reef & Open habitats, typically at depths of 0-40m. Most commonly encountered by divers at the shallower end of its range.

Encounter Tips

Best approached slowly and calmly. Avoid casting shadows directly over the animal. Neutral buoyancy and patience increase encounter success significantly.

Biology

Behaviour & Diet

Feeding Strategy

Nocturnal forager that feeds on molluscs, polychaetes, echinoderms, and carrion. It lacks the large claws of true lobsters and relies on its mandibles to process food.

Nocturnal forager

Reproduction

Females carry deep orange egg masses on their pleopods from late summer through winter. Larvae undergo a long planktonic phyllosoma stage lasting several months before settling.

Egg carrier

Behaviour & Defence

Produces a loud rasping sound by rubbing the base of its antennae against a ridge on the head, startling predators. Its spiny exoskeleton and powerful antennae provide further physical protection.
