Cave dwelling in the soft seabed at a depth of about 10 to 250 meters, with many spinous processes and no large claws. Active at night, hidden in rock crevices during the day. Eating dead or fresh fish, shrimp, shellfish, echinoderms, polychaetes, seaweed, etc., with a large appetite and strong hunger tolerance.
