How do elephants communicate?
Elephants have many ways of communicating with each other. They use the trunk, the ears, the tail, body language and naturally their voices too.The 
way an elephant holds its trunk tells other elephants whether it is going to attack or defend itself. Elephants also touch and smell each other with their trunks to find out where the other elephant has just been, what it ate and how it feels. Elephants are capable of cornmunicating through their senses and through smells. They express joy and excitement by flapping their ears. The sound of ears beating on the skin is picked up by other elephants as a message to get in touch. The elephant’s tail is used to probesorroundings which they cannot see.Elephants can communicate with each other over great distances using their voices and hearing. Fellow elephants who know each other with quiet rumbling or purring which reminds one of a running diesel engine. Calves bellow loudly for their mothers when they feel lost. Anxious, attacking and attacked elephants It is also known that elephant’s converse over great distances using infrasound which are low frequency sounds that human beings cannot hear. So, the next time you see an elephant standing frozen, with its head raised and ears sticking out, don’t disturb it…it is listening to a message that you cannot hear!
other using an assortment of squeaks, whistles, and clicks. It is thought that they are warning each other of danger or if Food is nearby, but we are not yet certain exactly what they are saying. Some scientists have also discovered that dolphins can be trained to understand quite complicated commands given to them.
little dance!Honey bees communicate with each other by dancing. The purpose of the dance is to alert other bees where nectar and pollen are located. The dance explains direction and distance to The honey bee performs two types of dances...the round dance and the waggle dance. The round dance is performed for food sources close to the colony and the waggle dance used for food sources that are far Other bees attending these dances somehow-no one knows exactly how- learn the distance, direction, and odour of the flower patch. Once they have this information, they too fly directly to the flower patch in search of pollen and nectar
The reason is quite simple… it wants to attract the female of its species which is known as a peahen! Dancing by the peacock is also an act to impress the peahen in front of him
ensuring the reproduction of a species. They also serve to warn other members of the species of danger, to mark out territory, and to indicate food When an ant is disturbed, it releases a pheromone that can be detected by other ants several centimetres away, causing them to run about as they work to remedy the Certain ants, as they return to the nest with food, lay down a trail of pheromone. This trail attracts and guides other ants to the Some pheromones are deposited with the urine or faeces of an animal to mark its territory and warn away intruders. This is why you see dogs urinating on lamp posts!
their own species to mate and reproduce. A male elephant seal, for example, will give a loud roar that tells female seals where to come ashore for breeding. Communication within the species is also important in the case of caring for the young. A mother gull must be able to recognize the calls of her own chicks so that she can find them in a thickly populated gull colony, and feed them.But communication also takes place between different species. This is especially true of species living in the same area. Recognizing the warnings given by another species can be very helpful in avoiding danger. In Africa, grazing animals pay close attention to the keen eared zebra. If a zebra suddenly starts running, the other animals know that an enemy is approaching, and will flee too.
important means of Taste and odour, electrical impulse and touch are also used to attract or drive away another animal. Sometimes an animal uses a combination of different mediums to get its messages across most effectively.
other species.Animals may use scents, to mark out territorial boundaries, to attract mates, to warn off intruders and predators or, in some cases, to attract prey. Animals of all kinds rely to a great extent on their hearing ability in order to succeed and survive, and this is called acoustic communication. Among mammals, generally speaking, small animals squeak, and large ones rumble. The acoustic communication signal most frequently heard by humans is, of course, bird song. The largest of all animals, the whales, appear to be experts in the art of communication by sound, with each whale of the same species having its own favourite ‘songs’ which it repeats at intervals.Visual signals may take the form of gestures and displays, facial grimaces, body posture or mimicry. Each species has its own way of using its facial expressions, body language, gestures and body markings to communicate effectively.At another level, animals may communicate a simple message through the art of mimicry. The markings on the wings of the peacock butterfly look like large eyes to frighten off its enemies. The same is true of the harmless hoverfly that resembles the wasp.
gestures, body language, displays, and even markings on the A peacock's extravagant display of feathers is a form of visual communication. The male rabbit will use the white underside of its tail to attract the attention of a female, while the female may use the white of her tail as a visual signal for her young to follow when she is leading them to the safety of the burrow.Dogs and wolves make use of body language, as do cats, monkeys and many other animals. The attitude of the tail when two wolves meet will indicate which of the two the superior is. Horses will hold their ears or tail in certain positions to signal pleasure or alarm. 
and sing cats when they meow and purr, and dolphins when they click and whistle. Many of these noises translate to simple phrases like 'I'm hungry', ‘I’m angry', 'feed me' and 'leave me alone'.Other animals use signals and sign language to talk to each other. Bees do a complicated dance to tell other bees in which direction to go to find food. Howler monkeys will howl to tell other monkeys to keep off their territory, and some birds sing both to attract mates and defend their Will we ever be able to understand what animals are saying? Maybe, one day. It's possible that, in the future, we'll have computers so powerful that they'll be able to decode the dolphin clicks even to translate Cuttlefish into English! 
though, when they are hurt, they purr to comfort themselves.
introduced by a British officer Colonel John Monroe in 1811. He was the Resident of the English East India Company in Travancore and their political agent in Cochin. He was also the Dewan of Travancore State. In the beginning, the Anchel service was used to carry only royal implements, government letters, and flowers as offering to the Sree Padmanbhas swamy Temple at Thiruvananthapuram, owned by royal family of Travancore. Later, the system was opened to the public for a fee of one chakram (copper coin used in Travancore. One rupee was equal to 28 chakrams).
would also carry parcels and letters. Fees had to be paid in person to the carrier, both by the person sending the mail, and the person receiving it.
carried on horse-back relay across the plains, deserts, and mountains of the Western United States. Compared to earlier delivery services, the Pony Express was very fast.
exchanged messages by carrier pigeons. These are specially trained pigeons which will find their way back home when they are released. The Egyptians and the Persians first used carrier pigeons 3,000 years ago. They also were used to proclaim the winner of the Olympics.
