We post mortem otters found dead in Wales, England, and Scotland. If you have found a dead otter please contact the relevant organisation below:
• Wales: Natural Resources Wales 0300 0653000
• England: Environment Agency 03708 506506
• Scotland: International Otter Survival Fund 01471 822487
Infographic on "Why is it important to report dead otters?": By reporting, you are contributing to vital scientific research on otters to investigate contaminants, disease, and population population across the UK. Have you found a dead otter? Please report it as soon as possible so that, with your help, we can continue our research. Please note the time, date, and National Grid Reference or what3words. Do not touch the otter. Infographic on "What happens are you report the otter?": The agency in your area will arrange to collect the otter. The otter will then be sent to Cardiff University Otter Project for post-mortem examination. Spatial, temportal, and biotic data is recorded in our database. This is why the information you provide is so important. We are able to ask questions about patterns across the UK, change over time, and differences between groups, such as sex, age, and reproductive status. We still need otters, no matter the cause of death! Although we aim to establish the cause of death (which is vehicle collisions in >80% of cases), this is not our main purpose of a post mortem. During the examination we collect data and samples which can provide information about ecological patterns and processes in wild populations. It is important that the otter is reported as soon as it is found. The freshness of the carcass allows the Otter Project to gain fundamental information and archive more samples for future research. Infographic explaining: "What otter samples do the otter project archive and why?" Since the beginning of the project in 1994, we have archived samples to retrospectively analyse when new questions arise, new methods are developed, and when funding becomes available. These are just a few examples of the tissue samples we retain and analyse for our research: Muscle samples are used for genetic analysis including research into landscape genetics and population genetics. Recent research from the project has revealed that although otter populations have grown, genetic recovery is lagging behind, and diversity remains low. Bones are used for morphometric analysis and heavy metal analysis. A recent collaborative study was published on the plasticity of the skulls which found morphometric variation between 3 distinct genetic clusters, coinciding to different diets and climates. Liver is analysed for chemical contaminants such as heavy metals, PBDEs, PFASs, PCBs, and OCs. PFASs are a large family of persistent synthetic "forever chemicals" and sample analysis revealed that otters are effective sentinels of PFAS pollution in the environment. Furthermore, we have found that chemical contaminants such as PCBs still exceeded toxic thresholds despite legislative controls being introduced decades earlier. Samples of gut content are taken near the rectum and retained for research associated with scent analysis, diet, and parasite screening. We have evaluated the effectiveness of metabarcoding methods as a tool for analysis of prey remains from faeces. Thank you for your continued support (featuring a picture of a eurasian otter on a river bank).

A few weeks ago The Otter Project was a part of Exploring Bioscience at Cardiff University. We have enjoyed showing the students some of what we do. We went on a walk along the Taff to survey otter spraint and our lead Dr Elizabeth Chadwick performed a post mortem in person for the students.

After being unable to perform post-mortems since February we are finally back in the lab! The placement students have enjoyed being able to begin their lab training and we have even found some abnormalities already. Otter #4715 had a very enlarged gall bladder and gallstones.

Today in celebration of #WorldRiversDay we wanted to recognise our river here in Cardiff - The River Taff, which has a supports a wide range of species including our beloved otters. World Rivers Day aims to spread awareness for rivers around the world, ensuring they continue to improve and thrive.

Following on from our previous post about the status of mammals in Wales, we would like to highlight ‘WMBAF’. The Wales Mammal Biodiversity Action Forum is a network of individuals and organisations who work on mammals in Wales; our project lead Dr Chadwick is one of the members.

A third of our native mammals in Wales are now threatened with extinction. @mammalsociety.bsky.social have made this infographic highlighting the action needed to support Welsh wildlife as a whole. Our work on otters is just part of wider conservation efforts for mammals in Britain.

Following some post mortems on otters killed on railways, we conducted further research. We discovered a serious and often unseen danger to otters in the UK: electrified 'third rail' railway lines.

Hi! I’m Sandra and I am a PhD student. My research focuses on developing and testing new genomic markers for non-invasive monitoring of otters, as well as evaluating the genetic diversity of otter populations in Portugal. I'm working in collaboration with the Environmental Genomics lab (University of Coimbra) and the Molecular Ecology and Otter Project groups (Cardiff University). I'm thrilled to work with the amazing Otter Project team and contribute to the conservation of this charismatic mustelid!
