Big brains and social living. Bottlenose dolphins, along with some other members of the dolphin family
delphinidae, have the largest brains outside of humans, when body size is taken into account. Scientists have long
puzzled over what dolphins do with such large, energetically expensive brains. The Monkey Mia, Shark Bay Dolphin
Research Project has revealed that dolphins, like some large brained terrestrial mammals, lead highly complex social
lives. Complex social relationships are thought to have played an important, if not primary, role in the evolution
of large brains in elephants, apes, humans, and now it seems, dolphins. In fact, some aspects of the dolphin society
in Shark Bay, such as multiple level male alliances, find their closest parallel in humans.
Knowledge as a force in conservation.
Many people think that if dolphins are unusually intelligent, then the conservation of dolphins should be more than
simply a numbers game--e.g., are there enough dolphins to sustain the population. Rather, we must be concerned
about the welfare of dolphins as individuals. Without evidence, however, it is easy for some to maintain the
opposite stance and dismiss the dolphins' large brain as an evolutionary anomaly--some scientists have suggested that
dolphin brains are primitive in structure (like hedgehogs!) and only serve to improve 'visceral function'.
The astonishing complexity of social relationships among the Monkey Mia dolphins suggests otherwise, and links
dolphins with a few species, including our own, where large brains and complex social living appear to have evolved
hand-in-hand. As we continue to improve our knowledge of dolphin social lives, it becomes increasingly untenable for
anyone to hold the belief that dolphins are essentially unsophisticated 'marine hedgehogs'. Inevitably, this
knowledge will strengthen arguments for the protection of dolphins and their habitats.
Research and conservation of the Monkey Mia dolphins Research has also played a direct role in the management and conservation of the Monkey Mia and Shark Bay dolphins:
Our research team is productive in publishing findings in high quality scientific journals and books.This is
the key measure of scientific contribution Journals include Nature, Proceedings of the National Academy of
Science, Animal Behaviour, Behavioral Ecology. The book 'Cetacean Societies' (edited and/or co-authored
by Monkey Mia researchers: Dr Richard Connor, Dr Janet Mann and Dr Amy Samuels) was listed as Outstanding Scientific
Title 2000, by Choice magazine. The royalties from the sale of this book go to the Cetacean Behaviour and
Conservation Award for Graduate students, which is administered by the
Animal Behaviour Society. To purchase a copy of Cetacean Societies

Although scientific contributions are critical for building knowledge, the public also plays an important role.
We insure the public has access to our findings through documentaries, radio interviews, popular articles, and public
talks.
The research is commonly featured in magazines and nature documentaries (e.g. National Geographic, PBS-NOVA,
BBC-Nature, ABC, Discovery ) and newspapers.
During their field seasons, researchers give public lectures at Monkey Mia several nights a week.
