Do hyenas laugh? Detailed answer Directory / Big encyclopedia. Questions for quiz and self-education Did you know? Do hyenas laugh? There is a species of spotted hyena called the laughing hyena. She is the largest representative of this family. When the spotted hyena hunts for prey or is annoyed by something, it emits a growl that inspires superstitious fear, reminiscent of a giggle or laughter. But, of course, the word "laughter" does not have the meaning that human laughter has. It's just a high-pitched scream that reminds us of laughter. The laughing hyena is a ferocious animal that reaches about 1 meter in height and 1,85 meters in length. Large hyenas can weigh up to 80 kilograms. During the day, the hyena sleeps in a burrow or cave. At nightfall, she crawls out in search of food. Hyenas often hunt alone. But sometimes they gather in flocks around a prey left by a lion or other predator. Their instinct leads them to the corpses of animals and they eat them without a trace. The hyena is a cowardly and vile animal, preferring to eat what others have obtained and abandoned. But they roam around campgrounds and villages and sometimes attack people sleeping in the open. They constantly accompany herds of cattle and antelopes. Hyenas can attack sick, very young or, conversely, very old animals. Spotted, or laughing, hyena of African origin, it lives from Ethiopia to the Cape of Good Hope. The peculiarity of the spotted hyena is that, unlike other animals, the female is larger than the male.

Their circulation is very complex, as there are many other causes that make the water move. One of them is that dense water goes down, while lighter water goes up. The densest water in the ocean is cold and salty. This is what it becomes when sea water freezes in the Arctic Ocean and near Antarctica. There is very little salt in the ice resulting from this freezing. The cold salt water left after the formation of ice sinks into the depths of the sea. The saltiest water in the ocean is in the tropics. This water is very warm and therefore not as dense as the cold and less salty water below. It remains on the surface of the ocean. Salt water is moved by the winds. Sometimes the winds and the contours of the shore connect the moving masses of water together. The water is forced to flow faster, forming a current. The currents are like rivers in the sea. The most famous current is the Gulf Stream, which was discovered by Benjamin Franklin. The Gulf Stream begins in the Atlantic Ocean near the equator. Constant winds near the equator almost always blow from the east. They push warm salt water past the Caribbean islands into the vast bay formed by the Florida peninsula and the east coast of the United States. Water accumulates here and then flows north to Cape Hatteras. Here the Gulf Stream becomes narrow and flows quickly. Its speed is several kilometers per hour. The current here is less than 16 kilometers wide and about 550 meters deep. Like a river on earth, the Gulf Stream does not flow strictly straight, but wags along the ocean surface. But, unlike a river, the Gulf Stream is not always in the same place, as it does not have a definite course. Many surface currents, such as the Gulf Stream, have several other currents underneath them. They are called countercurrents. They move in the opposite direction, but along the same path as the main surface current. The rotation of the Earth around its axis also affects the formation of currents.
