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.

"They clearly have something on their minds -- but to be perfectly honest, we haven't the faintest idea what that might be.". University of Southern Denmark. ScienceDaily shares links with scholarly publications in the. That is how the University of Southern Denmark marine biologists Magnus Wahlberg and Claudia Oliveira summarised their findings following their research trip to the Azores, where they ventured out to sea to attach listening instruments to seven sperm whales and subsequently attempted to analyse the strange tapping sounds they make, known as codas. They use these sounds for echolocation and as a form of communication.
Colleagues from Aarhus University and the University of the Azores accompanied the two researchers on the trip.

But the researchers found that a female which had recently given birth to a calf used a completely different pattern of clicks. Sperm whales communicate with other members of their pod using a handful of patterned clicks which all individuals in the group share, researchers have found. What does the sperm whale say?. Hi Mum/Dad! We only ask for specific personal information when you contact us or enter competitions, we never share this without your agreement. Young sperm whales can’t dive this deep for the first two to four years of their lives, so they’re looked after by other members of the nearly all-female pod, while their mother dives in search of squid. The sounds are very different to the sounds made by other marine mammals like humpback whales, which sing haunting songs to each other, or dolphins which whistle. Sperm whales were mainstays of whaling's 18th and 19th century heyday. Scientists think the animals use the sounds to show other whales in the pod that they’re part of the same gang. But they don’t have the sharpest eyesight or sense of smell.

Sperm whales have been particularly difficult to study, as their family groups tend to be large, with a proclivity for long-distance roaming.

What we discovered, however, was that individual sperm whales communicate individual messages to other individual members of the group," said Magnus Wahlberg, Associate Professor, Institute of Biology, University of Southern Denmark. In total they recorded 802 of these vocalisations from five of the whales, while the remaining two stayed quiet. When a team of researchers began listening in on seven sperm whales in the waters off the Azores, they discovered that the whales' characteristic tapping sounds serve as a form of individual communication. Sperm whales are fairly nomadic, travelling hundreds of miles across the open ocean to feed on squid. Materials provided by University of Southern Denmark. The whales make the sounds in the ‘big tub of oil at the front of their huge heads’, explains Rendell. ‘This female is probably identifying herself to her calf so that the calf can find her,’ says Dr Luke Rendell from the University of St Andrews, lead author of the report, published in Marine Mammal Science. Much like Morse code, these messages consist of a series of tapping (also described as clicking) sounds in a variety of combinations, such as four long taps followed by two short ones. The scientists registered 21 different messages. Scientists think the animals use the sounds to show other whales in the pod that they’re part of the same gang. The researchers found that the set of patterned clicks this mother used was subtley different to the other clicks they recorded.
