Main description

Despite its heavy appearance, it is able to swim thanks to the powerful contractions of its heavily muscled tail. This is the part that makes it very appreciated gastronomically.

Of nocturnal habits, the lobster is very voracious and feeds on everything it finds, although its preferences are focused on polychaetes, crustaceans, molluscs, algae, organic remains and worms. It emphasizes the fact that it is able to break the hard shells of the bivalves, in spite of lacking tweezers.

Curiosities

  • According to the Book of Records, the largest lobster was captured in Nova Scotia (Canada), and weighed 20.14 kg.
  • When the lobster grows, it must move the hard calcified shell that covers it, (this operation is carried out several times throughout its life). It is precisely when it is detached from its old armor that the animal is very vulnerable, since the new shell does not harden until after a few hours. This exoskeleton is often eaten by the lobster to replace the calcium reserves in its organism.
  • The lobster uses its long antennae to chase away its enemies, interposing them between it and the intruder. He also uses them to know his immediate surroundings through touch, a necessary skill in the low lighting conditions typical of the cracks and holes in which he lives.
  • During their migration or trip, the lobsters form a row touching with the antennas the tail of the lobster in front. Lobsters can form rows of up to 100,000 individuals, the row has the appearance of a giant eel or snake. If a daring animal tries to attack them, the lobsters form a circle with the tail towards the center and all its spines out. Watch the following video .
  • The name of the genus Palinurus evokes the helmsman of Aeneas (a prince of ancient Troy) who, according to legend, fell asleep at the helm and fell overboard into the sea.
