Dolphins in WDC’s adopt a dolphin programme doing well
According to a report published by Scottish Natural Heritage (SNH), with research undertaken by Aberdeen University, around 200 bottlenose dolphins make the Moray Firth and Scottish north east coast their home, and the population is ‘stable’.

More bad news as two humpback dolphin species are elevated to Endangered and Critically Endangered status!
Just the other day i blogged about how, as a direct result of bycatch, the IUCN had uplisted both the Irrawaddy dolphin and the finless porpoise to Endangered status.

Bycatch responsible for two more species being placed on the Endangered List!
Unfortunately, 2017 is not turning out to be a great year for whales, dolphins and porpoises with the numbers of some species dropping to worrying levels. Added to the list of “endangered” species by the IUCN are the Irrawaddy dolphin and the finless porpoise both having had their numbers more than halved over the last…Read More
Whales go from 'right-handed' to left
Scientist studying blue whale feeding habits have documented a switch from ‘right-hand’ to left when these huge creatures feed. Blue whales are similar to many other creatures when it comes to ‘handeness’ or laterality. They tend to always favour the right. However, results from a six year study of their behaviour off the coast of…Read More
