Marine mammal Marine mammal Marine mammals are aquatic mammals that rely on the ocean and other marine ecosystems for their existence. They include animals such as seals, whales, manatees, sea otters and polar bears. They do not represent a distinct taxon or systematic grouping, but rather have a polyphyletic relation due to convergent evolution, as in they do not have an immediate common ancestor. They are also unified by their reliance on the marine environment for feeding. Marine mammal adaptation to an aquatic lifestyle varies considerably between species. Both cetaceans and sirenians are fully aquatic and therefore are obligate water dwellers. Seals
The Mammal Society The Mammal Society The Mammal Society is a British charity devoted to the research and conservation of British mammals. The Mammal Society was formed in 1954, and the first ever spring conference took place the following year at The University of Exeter. The Mammal Society has a membership of around 2000 mammalogists, ecologists, conservationists, both experts and enthusiasts, all working to develop greater understanding of mammals and the conservation challenges they face. The Society runs national surveys for mammals, for example Mini Mammal Monitoring. You can find more information at mammal.org.uk/surveys_and_monitoring.
