COLOR PATTERNS.—Coloration among O. maorum individuals varied between two color morphs—individuals are either an orange-brown or a light to dark purple-gray. Individual coloration was conservative and color morphs mated freely. Color differences among individuals did not appear to be related to either size or sex. All O. maorum have numerous distinctive small iridescent white spots on the arms, web and dorsal arm crown, these spots being absent on the mantle (Fig. 2). These white spots were apparent on live, freshly dead, and frozen octopus, but appeared yellow-orange in preserved specimens and were less distinct. (Pg 661)
