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.

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.
Two and a half weeks after WDC and its conservation partners issued a Notice of Intent to sue the National Marine Fisheries Service (NMFS) for failing to adequately protect right whales, NMFS released a
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.
A group of fishermen had an unusual encounter off the coast of Northumberland recently when they came upon a northern bottlenose whale.
While these whales are occasionally seen in the UK, they tend to be found in the deeper offshore waters of the North Atlantic rather than the North Sea.
It was a slow start to this seasons fieldwork here on the Isle of Lewis in the Outer Hebrides.
The past five years have seen the population of North Atlantic right whales fall from 482 in 2010 to 458 in 2015 according to a new model used to estimate their numbers. Over the preceding twenty years the findings revealed the population had increased from around 270 whales in 1990 at a rate of just under 3%.
With hurricanes Irma and Maria causing devastation to Caribbean islands and the US coasts, we’ve been very concerned for dolphins and orcas held captive in marine parks in these regions.
