Emu grunting and hissing; note the inflating throat Emus. Western NSW, 1976. The vocalisations of emus mostly consist of various booming and grunting sounds. The booming is created by the inflatable throat pouch; the pitch can be regulated by the bird and depends on the size of the aperture.
Warmer water evaporates quicker, bringing more transfer of heat energy from the ocean to the air. This means that the hurricane then has more energy, so has stronger winds and has more rain, as ...
As sound travels faster and over a larger distance in water than in air, aquatic animals can use sound signals for long-distance communication while terrestrial animals cannot. [4] For example, a blue whale can communicate with another blue whale using sound over thousands of miles across the sea. [6]
Organisms that live freely at the ocean surface, termed neuston, include keystone organisms like the golden seaweed Sargassum that makes up the Sargasso Sea, floating barnacles, marine snails, nudibranchs, and cnidarians. Many ecologically and economically important fish species live as or rely upon neuston.
No matter the animal, he believes that the recording could be a conversation because of how the data was recorded. Scientists used an acoustic antenna: a group of underwater devices attached to ...
The blue color is sometimes wrongly attributed to Rayleigh scattering, which is responsible for the color of the sky. Rather, water ice is blue for the same reason that large quantities of liquid water are blue: it is a result of an overtone of an oxygen–hydrogen (O−H) bond stretch in water, which absorbs light at the red end of the visible ...
Two large emus on the loose in South Carolina ruffled the feathers of locals a week after dozens of monkeys escaped from a research facility in the Palmetto State.
Ocean color is the branch of ocean optics that specifically studies the color of the water and information that can be gained from looking at variations in color. The color of the ocean , while mainly blue, actually varies from blue to green or even yellow, brown or red in some cases. [ 1 ]
