Panulirus cygnus live as free-swimming larvae in the ocean for the first year of their life. Newly hatched, they can live up to 1,500 kilometers from the coastline. As they grow, they return to the coast to live for approximately five years on the reefs in water 40 meters deep, or less. After this period, they migrate to reefs that are deeper and further away from the shore. During this new stage of their life, the Western rock lobster is found in depths between 0-90 meters, and rarely as deep as 120 meters. As adults, they are nocturnal, so during the day they use coral and rock crevices for shelter.
Average depth: 0-90 m.
Habitat Regions: saltwater or marine
Aquatic Biomes: reef ; coastal
