As part of the Cetacean Strandings Investigation Programme (CSIP), we are often focused on the death of animal and can overlook the amazing lives of marine creatures before they sadly wash up along our coastlines. British waters are home to over 28 different species of whales, dolphins and porpoises, collectively known as cetaceans.
In the UK, the most numerous (and smallest) of these is the harbour porpoise (Phocoena phocoena). Unsurprisingly, these porpoises therefore make up the majority of strandings in the UK.
When a call comes in to the Cetacean Strandings Investigation Programme (CSIP) hotline, the details of a stranding can often be minimal and somewhat vague. An animal may be highly decomposed, inaccessible or lack features for it to be identified. As a research assistant for CSIP, my job is to investigate a stranding and try to gather as much information as possible so an accurate identification can be made. This blog post provides a simple guide for everyone to try and identify dolphins, whales and porpoises commonly washed up on British coastlines.
WARNING: This blog contains photographs of dead and injured stranded cetaceans which you may find upsetting
We take a diversion this week from the Microverse and our newest project, Orchid Observers, to introduce one of the projects that wouldn’t get anywhere without the general public reporting sightings, the UK Cetacean Strandings Investigation Programme (CSIP). Cetaceans are the infraorder of marine mammals that includes whales, dolphins and porpoises, and the Museum has been involved in recording their strandings on UK shores for over a century. So it’s over to Rebecca Lyal, Cetacean Strandings Support Officer at the Museum, to introduce the project and what she does as a part of it.
Warning: You may find some of the images that follow upsetting as they are of stranded and injured animals.
The CSIP was created in 1990 to unite the Museum with a consortium of interested parties to formally investigate the stranding of any cetacean, seal, shark and turtle upon the UK coastline. The Museum has actually been recording strandings since 1913 when the Crown granted it scientific research rights for the collection of data on the ‘fishes royal’.
The first recording was a Cuvier’s beaked whale that stranded in Northern Ireland during the summer of 1913. Since then there have been over 12,000 logged reports of whale, dolphin and porpoise strandings, that have ranged from the mighty blue whale to the common harbour porpoise, and even a rogue beluga whale found in Scotland.
