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.
Across the UK, many different creatures wash up on our shores. The Cetacean Strandings Investigation Programme (CSIP) is responsible for documenting stranded animals in the UK and retrieves a portion of those that strand for post-mortem examination every year. The main bulk of the project is made up of cetaceans – a group of marine mammals comprised of whales, dolphins and porpoises.
However, many people don’t realise the project also responds to strandings of sharks. Since 2007, the CSIP has recorded the stranding of basking sharks (Cetorhinus maximus) across the UK and more recently secured funding to expand the research to other large-bodied sharks such as porbeagles (Lamna nasus), angel sharks (Squatina squatina) and blue sharks (Prionace glauca).

The Cetacean Strandings Investigation Programme (CSIP) was recently called out to the stranding of a harbour porpoise, Phocoena phocoena, in Westward Ho! in north Devon. The porpoise was a suitable candidate to collect for post-mortem, and so plans were made for the strandings team to travel to pick it up.
As part of the trip to Westward Ho!, a ranger from Northam Burrows Country Park asked if the Museum was able to provide an identification on three whale vertebrae they had, to allow them to display the bones in their visitors centre. Little did anyone know the full story behind the vertebrae was about to be uncovered!
A recent stranding gained media attention last week as a Risso’s dolphin (Grampus griseus) washed up on a beach in Norfolk. The Cetacean Strandings Investigation Programme (CSIP) receives around 10 reports of Risso’s dolphins stranding every year, but most of these reports are concentrated in Scotland and the west coast of the UK. This unusual stranding in the southern North Sea meant it was crucial for the CSIP team to retrieve this animal for post-mortem. Post-mortems are essential for us to understand how the animal died, and the possible series of events which may have contributed or occurred leading up to its death.

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.

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.
