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).
A previously recognised species Jasus tristani, found around Tristan da Cunha in the southern Atlantic Ocean, has now been synonymised with J. paulensis. [2] This is an uncommon species throughout its range and is usually found at depths between 10 and 35 m (33 and 115 ft) but occasionally down to about 60 metres (200 ft).
Jasus is a genus of spiny lobsters which live in the oceans of the Southern Hemisphere. [2] They have two distinct "horns" projecting from the front of the carapace, but lack the stridulating organs present in almost all other genera of spiny lobsters. [2] Like all spiny lobsters, they lack claws, and have long stout antennae which are quite ...
Panulirus polyphagus grows to a length of about 40 cm (16 in). The antennal plate bears two large spines and there are no transverse grooves on the abdominal segments. Distinctive colour features by which this species can be distinguished from other spiny lobsters include a greenish-grey background colour and a thin white band near the hind edge of each segm
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 ...

In Florida, there is a season where the spiny lobster may be taken, usually from the beginning of August to the end of March, to protect the species during its main breeding season. A special "mini season" a few days before the start of the regular lobster season gives recreational divers a "head start" in catching them.
