Blue-spot Mantis Haptosquilla stoliura occurs in the tropical Indo-West Pacific in shallow coastal or nearshore reefs in tidal pools and among hard coral fragments in the intertidal area. The iridescent blue patch on the first maxillipeds is distinctive. The max. length of this species seems to be incertain. Some indicate 6.5cm as max. length, others 11.5cm. The length of this specimen is probably 10cm. \nThe ability of Mantis species to see circularly polarised light has led to studies to determine if the mechanisms by which their eyes operate can be replicated for use in reading optical information storage devices. \nTriton Bay, West Papua Province, Indonesia, \n3°54'41.05 S 134°7'18.205 E at 15m depth

Blue Striped Tunicate Rhopalaea circula occurs in the Western Central Pacific in a depth range from 6-18m. Tunicates do not have backbones, but they are vertebrates, why? At some point in their life cycle, they have a tail, a central nerve cord, a pharyngeal gill cleft and a notochord. Often mistaken for sponges, it's simple to test: Tunicates have two siphons and when disturbed, they can rapidly close them. Palau 7°6'55.26 N 134°16'11.96 E at 25m depth, deeper than the usually noted 18m maximum depth.
