Conserving Migratory Species

Some species of whales and dolphins can migrate many thousands of miles, travelling through the national waters of a number of different countries to get to their destinations.

New study uses facial recognition to identify dolphins

For many years, the leading non-invasive way to identify whales and dolphins has been to use photo-identification. Some markings on certain parts of their bodies, such as tail flukes in some species or dorsal fin in others, can remain largely unchanged throughout their lives which enables scientists to closely follow the lives of individuals.

New study on brain size and cultural behaviour in whales and dolphins

Authors of a new scientific paper published in the journal Nature Ecology & Evolution have put forward the theory that there is a link between brain size and social and cultural behaviour in whales and dolphins.  The researchers looked at 90 different species of whales and dolphins and suggest the bigger their brains, the more complex their lives can be.
