Abstract: A combined trap for lobsters and like marine crustacea and for octopi and like cephalopods comprising integrally constructed marine crustacea and cephalopod enclosures having a barrier therebetween to prevent cephalopods in the cephalopod enclosure passing into the crustacea enchlose. The crustacea enclosure is constructed to permit viewing from outside thereof of bait and/or crustacea in the crustacea enclosure to lure cephalopods to the trap. The combined trap provides independent entry to the respective enclosure with the entry to the cephalopod enclosure being constructed to occlude exit therethrough from the cephalopod enclosure of octopi and like cephalopods.
