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. ence&oref=slogin

Article: Sounds: SOUNDS IN THE OCEAN

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/s Salinity 1PSU = 1.4 m/s Depth (pressure) 1km = 17 m/s Ocean ~1500 m/s (air ~ 344m/s)
