Toothed whales, such as sperm whales, use sound waves in echo******** and this allows them to detect objects and organisms by means of sonar. Sperm whale sound waves bounce off objects that are in the water, returning to the whale in the form of an echo. This helps them to determine the size, shape, speed, distance, direction and the internal structure of the object in the water. The sound waves travel about one kilometre per second. Baleen whales, however, have vocal cords or folds that allow them to generate the loudest sounds on earth. Groups of killer whales appear to have their own vocal dialects.

Whales depend on sound for orientation. This ability is important for predators of the deep sea where light is greatly reduced. Only one percent of surface light travels to a depth of 100 meters and at 600 meters, the sun's illumination equates to that of starlight. They detectSperm Whale sound waves via a fat pad between the mandible and middle ear, as they lack an external ear. The short clicking noises whales produce is a form of echo********, and the sound that bounces off external sources forms a mostly clear picture of the obstacles which lay in their tremendous path. These short noises of one to five seconds long are a highly effective sonar system for the whales. One of the facts about whales that you should know is that every species of this majestic mammal employs echo********.

Humpback whales, as well as many other marine animals, use a form of song to communicate through the water. Sound travels over four times as fast in water than it does on land, making whale communication far quicker than human communication. A whale will use their songs most often as mating calls for the opposite sex. Whether alone with a female whale or competing with other whales to get the female whale's attention, the male whales sing beautiful songs as a type of "flirting". These songs can last as long as thirty minutes and are usually split up into small parts of about two to four minutes called themes. Whales often repeat these half-hour songs over and over for many hours and sometimes even days. Scientists have discovered that these songs are geographically specific because whales of the same area will often sing variations of the same songs, whereas whales from distant regions sing entirely different songs. Whale songs can also be used as feeding calls, to attract other whales to get ready for a hunt. They then form a group, lunging together to catch and eat schools of fish at a time. Their hunting call is about five to ten seconds long.

The sound of baleen whales is the loudest produced by any animal on earth and travels for many kilometres underwater. It may be used for long-range contract, calls for assembly, in their search of mates, as a greeting, threat or individual identification. They produce mostly low frequency sounds, which are for long distance communication, orientation and navigation. Whale communication occurs through low frequency moans, grunts and thumps, as well as high frequency chirps and whistles that are emitted by the whales.

Whales also communicate by means of gestures and body language such as breaching and slapping their tails. Whale noises such as forceful spouts may signal aggravation, and the slapping of pectoral flippers indicates arousal, excitement or aggression.

Whale Communication

Whales have a very intriguing method of communicating known as echo********. They are able to get their sounds to travel for miles as the sound waves move along in the water and get more power from bouncing off what is found in it. Then the sounds will echo back to the whale that send them. It is estimated that this form of communication can go one mile each second.

When you listen to the sounds that whales make to communicate, you will notice they are very unique. Clicks are part of the basis of such communication. They help the whales to navigate through the waters in addition to the form of communication as well. You will find that different species of whales with take on various forms of communication. The reason why whales communicate in this way is due to the fact that they don’t have an inner ear.

Another form of communication that only the humpback whales engage in is known as singing. When you listen to them for any length of time, you will find repeated patterns in them. It is almost like written lyrics that then come to a familiar chorus. They are more apt to sing these songs when they are migrating and mating. These songs can be up to 30 minutes in length. It is believed that the sounds can travel as far as 100 miles from the ******** of the humpback whale that created it.

Since whales create small pods you will find that there are communications that are varied in them. This is similar to how different ********s in the world have their own terminology. It is quite interesting to explore these various methods of whale communications. Researchers have been able to use it to accurately determine what is going on within pods. Yet they are very uncertain about plenty of it. They have also noticed that the communications among whales in captivity are often very different from those that are in the wild.

There is also a consensus that the various whale communications increase during the mating season. They males often sing low songs to the females as a way to court them. Some researchers also believe these low songs serve as a warning to other males in the area though to stay away. It could be a dual message that tells the female he is interested and lets other males know that they need to find someone else for their own interests.

Some will tell you that it seems like the sounds that whales use for communication have become louder over the past few decades. The belief is that due to the pollutants and toxins in the waters, there is more to stop the sounds from traveling the distances it needs to. Therefore they have adapted and make their sounds for communication even stronger and louder than before.

However, it is readily admitted by even the best researchers that we need plenty more information about whale communication before we can completely understand it. The newer technology we have allows us to accurately record whale songs from the depths of the waters around the world. This should serve as a valuable tool for getting more of it deciphered.
It does take a great deal of time though to record all of these types of communications. At the same time it is even harder to get the funding sources to help pay for the cost of men and women to break it all down. Many out there believe there are other aspects to cover for whales that are more pressing than communications. Therefore they would rather see grant money go for them.

Balinaların yiyecek kaynakları ve birbirlerinin yerini belirlemede kullandıkları asıl algı görme değil, duymadır. Birçok balina deniz dibindeki karanlık bölgelerde bir tür doğal “sonar” sayesinde avlanır.

Balinanın beyni, bilim adamlarınca henüz tam olarak anlaşılamayan bir şekilde, klik sesleri çıkarır. Objenin balinaya olan uzaklığı matematiksel bir hesaplama ile anlaşılır. Balinanın beyni, çıkardığı seslerin objeye çarpıp geri döndüğü hızı, bu iş için gerekli zamanla çarpar ve çarpımı ikiye böler. Elde edilen sonuç, objenin kendisine uzaklığıdır.

Üstelik balina ses dalgalarını, beyniyle belli bir noktaya odaklama ve bir ışık hüzmesi gibi gönderme yeteneğine de sahiptir. Geriye dönen dalgalar, hayvanın beyninde analiz edilir ve yorumlanır. Bu yorum, hayvana karşısındaki cismin biçimini, büyüklüğünü, hızını ve konumunu açıkça belli eder. Hayvanın kafatası yapısı, beyni bile tahrip edecek kadar sürekli ve şiddetli bir biçimde yaydığı ses bombardımanından korunmak için ses yalıtımlıdır. Bu canlılardaki sonik sistem inanılmaz derecede hassastır. Amerikan donanması teknolojisini geliştirmek için, deniz memelilerindeki sonar tasarımını taklit etmektedir.

Her biri yaratılış gerçeğinin delillerinden olan bu ayarlamalar, kara memelilerinde bulunmayan ve deniz memelisi olan balinalara özgü ayarlamalardır. Evrimciler bu mükemmel yapıların evrimle ortaya çıktığını iddia etmektedirler. Balinaları Allah’ın yaratmış olduğu gerçeğini inkar etmekte, balinanın, günün birinde denizde yaşamaya karar veren bir kara memelisinden hiçbir bilinci olmayan, rastlantısal mutasyon ve doğal seleksiyon mekanizmalarıyla evrimleşmesi sonucu ortaya çıktığını savunmaktadırlar. Elbette ki bu iddialar, cevaplanması gereken ve evrimcileri açmaza sokan soruları da beraberinde getirmektedir.

Hangi mutasyon balinanın sözde atası olan memelide bir sonar meydana getirebilir? Mutasyonların etkisi ve beynin balinanın yaşamı açısından önemi göz önüne alındığında, mutasyonların beyni tahrip edip balinayı sakat ya da ölü bırakacağı açıktır. Beyin bu rastlantısal süreçte tahrip olacağı yerde, nasıl olup da ses dalgaları üreten, bunları belli noktalara odaklayabilen ve objelerin yerini matematiksel hesaplamalarla belirleyen mükemmel bir sonar kazanabilir? Hangi mutasyonlar kara memelisinin ayaklarını yüzgeçlere çevirebilir ve tonlarca ağırlığı itebilen kuyruğu meydana getirebilir? Kuşkusuz bu sorular balinalardaki suyu verimli şekilde kullanmayı mümkün kılan sistemler, emzirme sistemi ve göz ve kulaklardaki basınca karşı korumalı sistemler hakkında da sorulabilir. Ancak evrimcilerin bu sorulara verebileceği hiçbir makul açıklama bulunmamaktadır.

Açıktır ki balinaların yaşayabilmesi için, ihtiyaç duydukları sistemlerin hepsinin aynı anda var olması gerekmektedir. Bu ise balinaların yaratıldığının açık delillerindendir. Allah balinaları mükemmel bir tasarıma sahip olarak yaratmıştır. Üstün güç sahibi olan Rabbimiz yarattıklarını koruyandır, bilendir.
