Dolphins In Shark Bay Western Australia Have Friendship Relationship Like Humans

scientists from one of the top ten great universities in the United Kingdom University of Bristol had a science project to study one of the cutest and smartest marine animal, they studied the dolphin's relationships and behavior, they chose an amazing place on the plant Shark Bay in Western Australia.

Shark Bay located in the farthest point of the west Australian continent, scientists consider this area as the oldest form of life because it has large seagrass beds it is estimated at 4,800 km2 which is a very rich source of food in the world made it home for many kinds of mammals like Dugong (sea cow) and dolphins the headline of Bristol University study.

By studying a local society of dolphins in Shark Bay scientists from Bristol University found that dolphins can make close friends could continue for decades with other dolphins based on the same or common interest in this matter dolphins are very similar to humans.


As many mammals lived on the water of Shark Bay the scientists noticed that the indo-pacific bottlenose dolphins observed by marine sponges using it as a tool to find their food and keep going in their life, the dolphins realized that this technique kept them alive so they keen to teach their children and past their knowledge from generation to another to help them find food in deep levels of seawater channels. The dolphins female are well studied and very talented in this technique and they keen to teach little kids how to find their food but the scientists focused on male dolphins in this study.

The study started in 2007 to 2015 the scientists collected data from 124 dolphins during the winter seasons in Shark Bay. the data was their behavior and gens and photographic data over the nine years of data collection they had huge data to analyzed and find the results the research team analyzed a sample of dolphins of thirty-seven male thirteen of them were spongers and twenty-four are non-spongers.


The long period of observation by the research time they noticed that the spongers dolphins spend more time with each other looking for the good food sources wile non-spongers don't. sponger dolphin made friends based on a similar interest which find food on the deep water channel and not relatedness or another factor.


According to Senior Research Associate at Bristol University Dr. Simon J Allen this process consumes a lot of time and it is large and individual work so it was long thought discordant with the needs of male dolphins in Shark Bay to invest time in forming close friendships with other dolphins.


A very expert researcher from the University of Zurich | UZH · Institute of Anthropology and Anthropological Museum and lead author of the study Manuela Bizzozzero said that male dolphins sowed us amazing social network system of making alliances with other males. These strong connections between males can remain for decades and are very important to each male's mating success.


We have to say thank you very much for the scientist's team from University Of Bristol and the Unversity Of Zurich for spent such a long time in this study it was about nine years of observation and data collection and gave us this very interest result now we know this smart animal share interest and make friends based on it. we also have to give credit to National Geographic Society which funded the study in cooperation with Australia's Sea World Research and Rescue Foundation Inc (SWRRFI) and Swiss National Science Foundation.
