It was recently discovered that spiny lobsters can also navigate by detecting the Earth's magnetic field. [18] They keep together by contact, using their long antennae. [19] Potential predators may be deterred from eating spiny lobsters by a loud screech made by the antennae of the spiny lobsters rubbing against a smooth part of the exoskeleton ...
Palinurus elephas is a common species of spiny lobster, found in the eastern Atlantic Ocean, from southern Norway to Morocco and the Azores, [7] and in the Mediterranean Sea, except its eastern extremes. [3] It lives on rocky exposed coasts below the intertidal zone, [2] mainly at depths of 20 to 70 metres (66 to 230 ft).

The file—consisting of a transverse vein with a single row of teeth—is located on the right wing, while the scraper consists of the sharply upturned right edge of the left wing. The thin glassy membrane of both wings, especially the larger left wing, functions as a diaphragm or drumhead to amplify the sound that is produced when the file is ...
