The Pharaoh Cuttlefish Sepia pharaonis lives in warm water (30°C) and is fast growing. They mate and spawn at 110 days and their life span is 240 days. They lay about 1500 eggs which take 14 days to develop at 28°C. Males are larger than females and most are larger than 1 kg. \n\nIn contrary to a squid's tail fins, cuttlefish have got a fin fringe running around all of the body side. A cuttlefish moves by undulating that fringe. Additionally, the cuttlefish can use the rocket propulsion typical of all cephalopods: Water is pressed from the pallial (mantle) cavity through the hyponome or siphon (a muscular tube), which is also used to direct the propulsion. So the cuttlefish is driven backward, which it uses mainly to evade an enemy, especially on short distances. \n\nThis specimen is howering near the Lava Flow of Neira Island, Banda Sea, Indonesia \n4°30'20.418 S 129°52'57.456 E at 7m depth

Grey Reefshark or Blacktail Reef Shark Carcharhinus amblyrhynchos occurs in the Indo-West and Central Pacific on continental and insular shelves and oceanic waters adjacent to them. The species is common on coral reefs, often in deeper areas near drop-offs to the open sea, in atoll passes, and in shallow lagoons adjacent to areas of strong currents in a depth range from 1-275m. Max. length female 172cm, male 255cm. Palau announced 2009 world's first shark sanctuary, banned all commercial shark fishing within its exclusive economic zone. 600000 sq km (230,000 sq mi) of ocean are protected now. As a result, divers see more sharks here than anywhere else! Palau, near German Channel, 7°7'13.279\
