When waves travel in deep water, they move without being really hindered, as the depths are often very deep. The wave transfers its energy without...
Dolphins and whales have an innate ability to navigate long distances using their sense of direction. However, sometimes this ability can be disrupted by natural...
The salinity of the oceans depends too much on the climate to be uniform. When it’s very hot, evaporation speeds up significantly, leaving the salt...
Underwater, sunlight is quickly filtered, and it's certain colors that suffer first. Indeed, water gradually absorbs colors according to their wavelength: first red, then orange, next yellow,...
Tsunamis, also known as tidal waves in French, are massive marine waves that are often triggered by certain major underwater events. One of the most...
Phytoplankton are microscopic organisms that float near the surface of the oceans and perform photosynthesis, somewhat like terrestrial plants. They alone generate about half of...
Dolphins have an anatomy adapted for speed which allows them to move quickly in water. Their streamlined and hydrodynamic body reduces water resistance, thus facilitating...
Underwater, colors gradually disappear as you go deeper. In reality, water acts as a filter that absorbs certain colors faster than others. Red is the...
Water is a great conductor of sound due to its high density: the molecules are close together, and sound easily travels from one to another. Underwater, sound...
Fish have various physiological adaptations that allow them to survive in different aquatic environments. Their gills are the key organ for aquatic respiration, allowing fish...
