GENERAL CHARACTERSTICS OF PALINURUS (SPINY LOBSTER)
- Commonly called as marine rock lobster or spiny lobster.
- Body is either not compressed or is dorsoventrally compressed and differentiated into cephalothorax and abdomen.
- It differs from other crayfishes and lobsters in having a small spine-like rostrum over cephalothorax.
- Cephalic appendages are antennae, antennules and eyes. Antenna sac is absent and antennae are much elongated.
- Thoracic appendages bear non-chelate but clawed walking legs of the same size.
- Abdominal appendages are fan-like, but the first abdominal segment is without appendages. The abdomen is long and extended and ending in a tail fan. The pleura of second abdominal segment do not usually overlap those in front.
- Meat of the lobster is very delicious and very much sought after.
- Larva is called as Phyllosoma, which is a broad and thin schizopod larva.
The rock lobster produces a peculiar sound like creaming of leather by rubbing antennal pad against a sternal keel.
The animal is contains much elongated antennae, fan-shaped abdomen, uropod and all above features, hence it is Palinurus.
