  5. Your deep ocean creaturesfrom the HW#2: • Anglerfish • Rattail (Grenadier fish)‏ • Dumbo octopus • Tubewarm • Kraken (the giant squid)‏ • Kiwa – Yeti crab • Sea pig • Vampire squid • Blob fish • Deep sea coral • Gulper eel • Depressed Yeti crab • Amphipod • Viper fish

  6. Deep ocean adaptations • The clam Calyptogena magnifica, which lives on deep-sea vents, depends on a bacterium to supply it with nutrients; the bacterium is transmitted through the clam’s eggs. The same goes for our mitochondria — the remnants of bacteria that live in our cells and provide us with energy. http://judson.blogs.nytimes.com/2008/04/08/a-mutual-affair/index.html  http://www.nytimes.com/2007/05/22/science/22deep.html?_r=1&ref=science&oref=slogin

  7. The speed of sound in water increases with increasing water temperature, increasing salinity and increasing pressure (depth). The approximate change in the speed of sound with a change in each property is: • Temperature 1°C = 4.0 m/sSalinity 1PSU = 1.4 m/sDepth (pressure) 1km = 17 m/s • Ocean ~1500 m/s (air ~ 344m/s)‏
