Exotic Fishes In Scenic Seascape
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. In 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. This specimen is howering near the Lava Flow of Neira Island, Banda Sea, Indonesia, 4°32'7.9618 S 129°52'30.6844 E at 9m depth
