Ecology of Panulirus cygnus

Main Ref.	Holthuis, L.B., 1991
Remarks	Occurs at depths between 0 and 90 m, rarely as deep as 120 m. The species are nocturnal and shelter in the daytime in rock crevices and among coral. They are omnivorous. They undertake limited migrations (Ref. 4). Juveniles spend 5 to 6 years in shallow-water reef areas, then moves offshore. They return from nocturnal foraging to the same den or one nearby, implying knowledge of topography (Ref. 106918). Phyllosomata of this species is observed to hitch and feed on its host salp Thetys vagina (Ref. 108806). Feeds on the coralline alga Corallina cuvieri (Ref. 122156).
