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.

Godeffroys Worm Cucumber Euapta godeffroyi occurs in the subtropical and tropical Indo-Pacific from South Africa to Hawaii in a depth range from 0-77m, max. length 40cm. \nThe spicules (microscopic calcareous structures that project through the skin) are a mixture of anchors and perforated plates with large holes.  \n\nThe nocturnal species is a deposit feeder spending the day hidden among the rubble and corals. It emerges at night, crawling along using its anchor spicules for adhesion, and extending its tentacles onto the sediment (like this specimen) which sticks to them; food particles are passed to the mouth where they are scraped off. The sea cucumber selects the more nutritious particles it finds and consumes several times its bodyweight each day.\n\nTriton Bay, West Papua Province, Indonesia\n3°54'2.5416 S 134°6'23.8608 E at 9m depth by night
Ideal for saltwater aquariums, nooks of marine habitants, The giant tube worms live in large groups in the bottom of the Pacific Ocean at depths of 2000-4000 m, near black smokers. Tolerate extreme conditions of high temperatures and high concentrations of sulfur. Like other forms of life that thrive around the vents, giant tube worms have developed biochemical adaptations through which they can live without sunlight.advertising
