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.
A survey of dolphins off the coast of Abu Dhabi, the capital of the United Arab Emirates, has identified the area as a key habitat for Indo-Pacific humpback dolphins in the Indian Ocean. The Environment Agency - Abu Dhabi (EAD) began studying the dolphins in 2014 and has estimated the local population to be around 701, much larger than has been recorded anywhere else.
Researchers in Pakistan have recorded video footage of what is believed to be the first confirmed sighting of a blue whale mother and her calf off the coast of Pakistan. While bones of blue whales had been found in the country, a live whale had never previously been seen.
The sighting by a skipper with WWF-Pakistan, was made off Churna Island in Balochistan.
Blue whales are the largest creature ever to have lived on Earth and their numbers were severely reduced by years of commercial whaling during the last century.
Whale poo and its contribution to marine productivity and climate change mitigation will be part of the agenda of the 28th International Congress for Conservation Biology, which opened July 23 in Cartagena, Colombia.
Scientists will consider how a range of eco-friendly services provided by whales could underpin conservation decisions made by large organisastions that determine the future of the planet.
