Latest developments
A black Labrador named Sgiath has been named Animal of the Year in a national competition organised by a Scottish wildlife charity. The award, presented at a ceremony in Edinburgh, recognises the dog's unprecedented success in locating the invasive marine organism colloquially known as "sea vomit". Conservationists say the dog has been instrumental in early‑stage detection of the pest, allowing rapid removal before colonies can establish.
Sgiath was trained by the Marine Conservation Society in partnership with the Scottish Wildlife Trust. Handlers taught the dog to identify the faint scent of the organism's gelatinous bodies, which often cling to rocks and seaweed in intertidal zones. Since the programme began in early 2022, Sgiath has reportedly flagged more than 200 infestations along the western coast of Scotland, a figure that exceeds the combined detections made by human survey teams in the same period.
The recognition follows a series of media reports that highlighted the dog's breakthrough work. The BBC described the animal as a "hero" for its contribution to protecting marine habitats, while The Independent noted that the award marks the first time a working dog has received such a national accolade. The Herald added that the achievement demonstrates the practical value of scent‑detection dogs in marine conservation, a field traditionally dominated by visual surveys and laboratory analysis.
Organisers of the Animal of the Year competition said the decision reflects a growing appreciation for non‑human contributors to environmental stewardship. They noted that Sgiath's work has helped prevent the spread of sea vomit, which can outcompete native species, alter food webs, and threaten local fisheries. The award includes a cash prize that will be reinvested in expanding the canine detection programme to other coastal regions of the United Kingdom.
Why it matters
The invasive sea vomit organism, officially identified as an introduced tunicate species, poses a serious risk to marine biodiversity along the British coastline. By forming dense mats on rocks and kelp, it reduces habitat availability for native invertebrates and fish, potentially impacting commercial shellfish stocks and recreational angling. Early detection is critical because once the species establishes a foothold, eradication becomes costly and often ineffective.
Sgiath's success illustrates a cost‑effective, rapid response tool that can be deployed by local authorities and conservation groups. The dog's ability to locate hidden infestations reduces the need for extensive diver surveys, saving time and resources. For coastal communities that rely on tourism and fisheries, the programme offers a tangible safeguard against ecological and economic damage.
Background
Sea vomit is an invasive marine tunicate first recorded in the UK in the early 2000s, likely arriving via ballast water from overseas shipping. Its rapid growth and tolerance for a wide range of temperatures have allowed it to spread along the Atlantic coast of Britain and Ireland. Traditional control methods have included manual removal and chemical treatments, both of which have limited success and can harm non‑target species.
In recent years, wildlife organisations have explored the use of scent‑detection dogs for marine applications, building on successful programmes that employ dogs to locate invasive rodents and amphibians on land. Dogs possess an acute olfactory system capable of distinguishing minute chemical signatures, making them well suited to detect organisms that are otherwise difficult to see.
The Scottish Marine Conservation Society launched a pilot project in 2022 to train dogs for this purpose. Sgiath, a retired assistance dog, was selected for his calm temperament and strong work ethic. Over a series of controlled training sessions, handlers paired the scent of sea vomit samples with positive reinforcement, enabling the dog to learn the target odor.
What happens next
Following the award ceremony, the Marine Conservation Society announced plans to recruit two additional dogs for the detection programme, extending coverage to the coasts of Wales and Northern England. Funding from the award prize and new sponsorship deals will support the purchase of specialised equipment and the training of volunteer handlers.
Researchers also intend to publish a peer‑reviewed study detailing the detection rates, false‑positive rates, and cost analysis of the canine approach, providing a template for other regions facing similar invasive marine threats.
Summary
- Sgiath, a black Labrador, was named UK Animal of the Year for detecting invasive sea vomit. - The dog has identified over 200 infestations along Scotland's western coast since 2022. - Early detection of sea vomit helps protect native marine life, fisheries and tourism. - The programme demonstrates a cost‑effective alternative to traditional diver surveys. - Expansion plans include adding more dogs and publishing scientific results to guide future efforts.
